The plane did not land in Guiyang, but flew directly to Shuicheng at the junction of Yunnan and Guizhou.

Shuicheng was the coal and iron center determined during Yang Qiu's reign in the southwest in Xinhai years, and after the completion of the southwest railway network in 1927, the state-owned Shuicheng Iron and Steel Group rose from this remote town. After more than ten years of development, Shuicheng has become the largest steel center in southwest China, with an annual steelmaking capacity of 5 million tons. It not only effectively supports the construction of the southwest, but also has become a special metallurgical material base of the 3010 plan together with Chongqing Baotou because of its remote geography and strong confidentiality, and has formed pairs with a large number of institutions of higher learning such as Southwest University, Guizhou University and Kunming University. At present, the high-strength pressure-resistant steel used by the Navy for submarines, and the torsion bar of the Type 36 tank are all produced here.

As soon as he got off the plane, Jiang Baili saw Yu Dawei and several other persons in charge of the 3010 plan, and even Yang Qiu's eldest daughter was in the crowd. "Sisi, why are you here too?" Yang Qiu also wondered why her daughter came here.

"Dad, why did you forget that the computer control system was contracted by our Lenovo company."

"Computer?" Although Jiang Baili is old, he has also learned a lot of new technical terms by Yang Qiu's side over the years. Computer technology is used in intelligence decipherment, air defense command, "Tianquan" fighter jets, and the latest H-12 bombers, but how can a metallurgical group use expensive and complex computers?

Yu Dawei quickly solved his doubts: "It is a new oxygen top blowing converter, which can shorten the steelmaking time by about four times, and requires computer control technology." Yu Dawei stood in the steelmaking workshop and pointed to a new type of converter to introduce to everyone.

After taking over the responsibility of the 3010 project from Leng Jie, he has become the head of various national research programs in China. Although he rarely participates in actual research, he has been traveling to major laboratories for many years, providing logistics support and scheduling resources for everyone, and has made great contributions.

"Quadruple shortened?!" As soon as he finished speaking, Jiang Baili suddenly screamed in surprise. Domestic steel production has been at a peak of 45 million tons in recent years, and it will take time for the new plant to be expanded after the war. Second, because the war took away too many resources and manufacturing power, the Ministry of Industry and Commerce believes that it will not usher in a new round of steel expansion until 45 years. But what is heard now? Wouldn't it mean that the production capacity could skyrocket to 180 million tons per year?! Oh my God! The United States just exceeded 70 million tons last year.

Yu Dawei was sweating profusely, and hurriedly corrected: "Principal, that's not how it is counted. It takes time to promote new technologies, transform equipment, and train workers. Besides, no matter how high the crude steel output is, if the processing capacity is not increased, it will only cause steel mills to reduce production, or it will be a matter of malicious competition to reduce prices. ”

"That's right." Jiang Baili agreed, but his expression was still eager. Even his steps are brisk. "Baili, why are you here too?" After walking into the steelmaking workshop, Yue Peng was talking with several technicians who were preparing to open the furnace, and when he saw Yang Qiu, he immediately came up to say hello. "This is the new steelmaking furnace?" Jiang Baili, who was anxious, interrupted him and leaned among the technicians to ask questions.

In fact, as early as the beginning of the 3010 plan, Yang Qiu proposed the oxygen top blowing steel method, and handed over some things he knew to Leng Jie. At that time, he thought that the oxygen top blowing converter should be very simple, because Germany achieved large-scale industrial oxygen production during the European war, and the converter appeared after the war. Therefore, when planning the national steel mills, he did not build a large number of furnaces, and always thought that he could get it before the war and then burst out with a higher steel output than the United States, which is also one of the reasons for the lack of domestic steel production in advance. It was only later that he understood. This is actually a very difficult technique. The high-temperature resistant three-hole nozzle, how to control oxygen at twice the speed of sound, how to master the chemical reaction of molten steel in the furnace to achieve the best color, as well as new furnace bodies, brackets, trunnions and tilting machinery, etc., have led to repeated failures in research. In particular, the parameters that need to be controlled and adjusted are quite complex. It was no longer possible to solve the problem by manual labor, so it was not until last year that Hua Luogeng manufactured the first transistor computer, and the volume life reached a satisfactory level. Only then did he lead the science and technology team to work with Lenovo to overcome the technology of fuzzy control of the nozzle with a computer.

To put it simply, according to the test data, according to the mathematical model established by the mass balance and heat balance, the amount of blowing and oxygen blowing is allocated by computer. During the operation, the parameters are set according to the type of smelting, and then the computer controls the mechanical nozzle according to the parameters to realize the automatic metallurgical operation. Of course, this system is still very primitive, and the volume is huge, which cannot be compared with later generations.

After Yang Sisi introduced the principle of computer control to Jiang Baili and others, the skilled workers began to operate the converter. After just twenty minutes, a furnace of molten steel is poured into a crucible and sent to the hot rolling mill. In order to demonstrate to the president, more than a dozen material metallurgical experts also moved the detector to the workshop, and used a lot of technical means to prove that the crude steel trained by the oxygen top blowing furnace is better than the current refined steel in terms of impurities and strength.

"Promotion, we must promote it as soon as possible!" Jiang Baili was very excited, and even Yang Qiu nodded frequently, and after twenty years of hard work, he finally won another milestone in metallurgical technology.

Yu Dawei and the technicians were even happier, after all, the new steelmaking furnace was like their children. But when it comes to promotion, he still has a calm and cautious attitude: "Shuicheng has been renovated, we have roughly calculated, if we use local ore, the output can triple last year to 15 million tons (low-grade ore needs to be screened first), if you use India's high-grade high-energy direct steelmaking ore, 20 million tons can also grit your teeth and try." In terms of promotion, state-owned factories in Anshan, Baotou and Urumqi are not a big problem, but private factories in Changchun, Zhanjiang, Hanyang and Chongqing are involved in technology transfer and other issues that need to be coordinated. And now is the time of war, and the equipment transformation will delay the start of construction, so you can only come from one family to another, otherwise there will be chaos. ”

"David is very comprehensive, and the promotion of new technologies should also consider reality." Yue Peng praised. He is different from Jiang Baili, who is no longer in the military, so if he has anything to say, he must consider the problem more comprehensively. But on the high-grade ore, he made a guarantee: "You can rest assured that high-grade iron ore, as long as I am still a marshal, the Indian theater of operations can ensure that at least 30 million tons of concentrate will be shipped back a year!" ”

With the marshal's assurance, the technicians and the factory director all patted their chests and promised to complete the goal of 20 million tons. That is to say, the crude steel output forecast at the beginning of the year will increase by 15 million tons to 60 million tons! Finally, in order to encourage everyone, Yang Qiu also deliberately took care of Yu Dawei and the factory director in person to sort out the list of meritorious services as soon as possible. He submitted it to the National Assembly for heavy awards and even decorations for scientific research and skilled workers.

The adjustment of the navy and Yang Qiu's visit to the new steelmaking technology all indicate that when the East Asian war is coming to an end, the work of restarting national construction and restoring normal people's livelihood and economic order has been put on the agenda.

Of course, war is still the main theme at the moment.

So after the group left the steel mill, Yang Qiu immediately pulled Jiang Baili, who was about to return to Ryukyu in advance, into the car: "Don't leave yet, I'll go to see the new bomb experiment later." ”

"New bombs?" Jiang Baili, who had just opened his eyes, was secretly shocked, what kind of bomb was worth seeing Yang Qiu in person? Is it still in the 100,000 mountains of Guizhou? "The new bomb is aimed at mountainous areas and some special terrain, and the degree of secrecy is relatively high, and the terrain and secrecy conditions here in Guizhou are relatively good." Yue Peng sat next to him and introduced the reason for placing it in Guizhou.

When the three of them spoke. The convoy had already returned to the airport, and when it got out of the car, it was seen that Air Force Commander Yu Lei and many officers were watching a giant bomb that had been loaded into the improved magazine of the H-7. The bomb is larger than the 5-ton Fury, with a round head, which is obviously not a ground-penetrating bomb, and a parachute bag in the tail, and the wings are painted in striking red.

The bright color and the skull logo on the surface of the bomb made Jiang Baili wonder, because it was very much like a poison gas bomb. To know. China, like the belligerents, was armed with a large number of poison gas bombs, and only because of the terrible effects of the last great war were the warring countries were more restrained. So he looked at Yue Peng and Yu Lei, and there was still some dissatisfaction in his words: "Zi'an." How to use this? ”

Yue Peng smiled: "Brother Baili, if this is a poison gas bomb, the soldier should wear a chemical protective suit." ”

"It's not a gas bomb, it's a daisy cutter!" Yang Qiu said loudly. The gaze is eager.

"Daisy cutter?"

This name, not to mention that Jiang Baili is inexplicable, even many people in later generations do not understand. But change the name to the cloudburst bomb. It's clear what kind of monster this is.

The cloudburst bomb is a high-powered bomb that appeared in the Vietnam War, known as the "civilian atomic bomb", but in fact, the cloudburst bomb is not a civilian at all. Everyone knows that the cloudburst bomb is filled with GSX slurry explosive (also known as cloudburst agent), the main components of which are ammonium nitrate, aluminum powder and polystyrene. After the bomb explodes, the cloud burst agent will quickly form an aerosol state of fuel, which will penetrate into the interior of various fortifications, and the ability to strike at fortifications in a closed state is much higher than that of ordinary bombs. And because the fuel consumes oxygen, it will also bring another new killing effect, suffocation! If the meteorological conditions are suitable, its explosion can cause severe hypoxia in the explosion area for more than ten minutes. In this way, even if the enemy army escapes the explosion, he will die of suffocation due to lack of oxygen.

Of course, Yang Qiu would not let go of such a powerful bomb, but very few people knew that if these three main ingredients were mixed, what he would get was not a cloud explosion agent, but a suicide explosion! So the cloudburst agent is really secret, and it is a special thickener (which is not written for the sake of harmony). The role of the thickener is not only to thicken the three main materials, but also to inhibit their chemical reactions, so that the cloud burst agent becomes a chemical synthesis agent that can be safely processed, stored and transported.

Cloud burst agent is not simple, and requires a strong foundation in the chemical industry. In later generations, cloud explosives could be produced in large quantities at a low price because of the rapid development of technology and the chemical industry. However, even with the advancement of science and technology, there are only a handful of countries that can independently develop cloud burst agents, so cloud burst bombs are by no means civilian atomic bombs.

In this world, in order to improve the national chemical industry, Yang Qiu took advantage of the European war and economic crisis to introduce the chemical manufacturing industry, and through high-priced hiring, expatriate study abroad and other means, before the war, he also cooperated with German companies such as Farben, and finally spent 30 years to establish a chemical industry system second only to the United States, Germany and Britain, which has the ability to mass-produce cloud explosives. Of course, Europe and the United States also have the capability, but in order to synthesize cloud explosives, they need to conduct a large number of time-consuming synthesis experiments like China.

Everyone was confused by this complex technical terminology, but fortunately, all Yue Peng and Jiang Baili needed was power and output data.

Half an hour later, the special plane under the protection of fighter jets took the lead in arriving at a specially selected valley, in order to achieve the experimental effect, the air force has transformed the valley, culverts and tunnels have been dug in the mountains on both sides, and a simulated small village has been built in the center of the valley in accordance with the wall standards of the Soviet cold zone.

"It's coming!"

While everyone was talking, bombers and an observation plane slowly flew from the south, and Yang Qiu immediately picked up the telescope. Through the binoculars, you can see that the bomber's compartment hatch has been opened, but the bomb is not yet visible due to the angle.

A minute later the bomber began to descend and dropped bombs at an altitude of 1000 meters. The red tail fin is very visible, and when the bomb falls to a height of about 200 meters, the tail parachute opens, and the bomb slows down and slowly falls towards the center of the village. At a distance of about twenty or thirty meters from the ground, this cloudburst bomb that completely imitated the design of the "daisy cutter" suddenly exploded. What was eye-opening was that the bomb did not immediately explode into a fireball, but a large stream of gaseous substance, and to the naked eye, the entire village was enveloped in gas.

"This is aerosol boom!" Before Yue Peng could finish asking, a flash of fire suddenly flashed in the white mist, and then the entire aerosol exploded violently! Even though it was still a few kilometers away from the village, the air wave still affected the 40-ton special plane, which scared the two pilots into chilling their vests. A huge mushroom cloud churned and rolled at a speed visible to the naked eye, enveloping the entire village in a sea of fire, and the explosion generated a huge air pressure that pushed the surrounding trees in patches.

It took more than ten minutes for the sea of fire to gradually dissipate, and then everyone saw that all the buildings and trees within a radius of 300 meters of the explosion point had been razed to the ground, and the big trees, shrubs and even wild grasses within 100 meters were burned to ashes.

The caves that are still burning on both sides of the cliffs show that it is real to infiltrate into the burrows and consume oxygen. "The power is about 40 tons of yellow explosives." Yu Lei, who dealt with bombing every day, quickly judged the approximate explosive yield. The 6,800-kilogram bomb can produce an explosion power of 40 tons, which really frightened Yue Peng and Jiang Baili, who had seen the atomic bomb explosion. Because the latter is a strategic weapon, and it does not have the ability to manufacture it in large quantities, it is impossible to use it as soon as it is said, but the one in front of it can be put into actual combat anytime and anywhere.

"The price of cloud explosives is still relatively expensive, and we have begun to expand production to see if we can reduce the cost, and it is estimated that we will be able to produce 3,000 tons per month by the end of the year. Just now, this kind of extra-large is mainly used for tackling fortifications and special purposes, and the bombers carrying it have to be specially modified, so the output will not be very large. The 800 kg front-line tactical version and the 1500 kg strategic bombing version for attack aircraft are the main models. Yu Lei introduced: "I am ready to put the next stage of actual combat experiments in the Urals, strike." ”

"Wait, I want to put it in Japan first."

Before Yu Lei finished speaking, Yang Qiu suddenly interjected faintly, took out the translated telegram brought back by Jiang Baili and handed it to Yue Peng and Yu Lei: "The news of the Soviet-German alliance has made Hirohito change his mind. So I wondered if I could take advantage of the powerful killing power of the cloudburst bomb and the suffocation effect to start the clearance operation early and help Tokuda Ball clear the obstacles. ”…… (To be continued......)
