What exactly is the process of turning iron ore into steel? In the Huaibei Campaign, the steel used in the Rendi base was not self-produced, but so-called external support. The real situation is a large amount of carbon steel that Ren Di exchanged from the Evolution Battlefield. As a basic raw material for the manufacture of weapons. As for the production of steel by local converters in the base, the quality has not been good. Ren Di has never started a production line for the manufacture of long-barreled guns. Instead, the problem of manufacturing long-barreled artillery was solved by importing Haisong's special steel.

If it is forcibly used, what will happen if the converter steel in the base area is made of artillery? The trachoma in the inner chamber of the Qing Dynasty artillery is enough to hold a bowl of water. However, due to the imprecise control of the material. Trachoma is absolutely there. The performance of the cannon will be similar to that of the American Civil War artillery in the Rendi plane. This Red Republican Army has few qualified artillery, and with such a heavy and low-performance artillery, Ren Di plans to take it out and look for abuse in front of the Imperial Third Army, which purely imports the advanced equipment of the Hai Song Dynasty.

And now Ren Di has finally mastered how to turn iron ore coal mines of different standards into qualified steel. Ren Di can cast artillery that has no generation difference with this era. In the 21st century, the legendary alloy steel and the cannon steel manufacturing technology of the electric brake furnace are not to be discussed. Before 1860, the front-loading gun technology of gray cast iron casting was too backward, and in the current era, it was the artillery technology provided to the Ming Dynasty several decades ago by the Hai Song Dynasty to fight wild boar skin (a little more advanced than the Napoleonic cannon, the artillery technology during the Civil War. ）

The journey of artillery from a unit to a unit, from a short iron cannon to a slender cannon, was after 1870. In the 1860s and 1870s, with the rise of crucible steel, the Krupp Brothers Foundry used large pieces of crucible steel to cast steel cannons, but the early steel was a mixture of high-carbon steel and wrought iron, and there were many impurities and it was easy to burst.

The highlight was in the seventies of the nineteenth century. In this era, the industrial steelmaking method appeared, and converters and open-hearth furnaces all appeared. The glorious era of artillery came, and then on the pure steel battleships, the idea that the turret is good is good, and more is beautiful, so that artillery technology has advanced by leaps and bounds. One of the step-by-step technical parameters is not to be discussed. The production of artillery barrels is no longer cast, but forged out barrels, and then the large tubes are put on small tubes, and the large red tubes are put on small tubes. The combination of tight seams, when the large tube is cooled down by the principle of hot # expansion and cold contraction, the small tube achieves a new stress to the inside. This is artillery self-tightening technology. This casing technology is more advanced than other wire winding self-tightening technologies for winding steel bars. At the Battle of Jutland, the Krupp cannons of the German battleship casing fought in terms of penetration and the British fleet was sour with the technology of winding wires.

The birth of the casing artillery required the climbing of a technology tree - the hydraulic press. There is no more technical cheating in this plane than Ren Di. At present, there is a 2,400-ton hydraulic press in the entire base area of northern Anhui. The parts of this hydraulic press come from the tireless transportation of special materials in this world. As for the formation of parts, they are all processed by Ren Di with dozens of tons of small hydraulic presses.

This hydraulic press, which is more than 2,000 tons, is driven by the power of a steam engine and can handle cannon barrels and other steel plates. That is to say, now Ren Di does not use his talents, and the northern Anhui base has a production line that can independently produce cannons. And under the action of various polishing and boring machines, the artillery gas-liquid recovery machine is also used in the new artillery production line. The fire of the rack back gun requires a heavy metal gun mount to stabilize. And even if the gun is stabilized, it still has to be taken back a little, and the angle of the barrel changes, and the parameters have to be set anew. In the process of squeezing the liquid in the casing, the kinetic energy is released, and then the compressed air in the casing slowly resets the barrel. This requires a tight connection between the barrel and the casing. I can't leak sideways. Of course, the advanced materials that also came from Haisong have become advanced processing tools.

Officers in the Huaibei Red Zone, who have visited the scene of an artillery production plant, will be shocked. A steel is forged into a short column, and then a small hole is drilled, and after the red is spared, this short and thick cylinder is inserted into a steel column (mandrel) and then put on the hydraulic press, and the rolling forging of the face is changed, and the short and thick cylinder billet becomes longer and thinner along the steel column under pressure. It's not a one-time success (Ren Di's talent for unfolding can be a one-time success.) It took many times to burn red and be crushed many times before it could be pressed into something in the shape of a cannon barrel. And that's not all, there's annealing, which is to slowly heat the thing to a certain level to maintain that temperature, and then let the thing cool down slowly at a standard and appropriate rate. The cooling rate should also be controlled. Annealing can reduce the brittleness of the barrel.

Li Youran and several of them saw the artillery factory and saw this process of continuous heating, a heat treatment furnace that consumed a lot of gas. Finally understand why the consumption of the military industry is so large. I also respect the experts from Guizhou. Because of this complicated process, if you try it yourself. The amount of gas and steel consumed will be massive, enough to drag down the finances of northern Anhui.

In the final scoring stage of the novice mission, Ren Di has never been so close to a medal base in the steam era. If you take the initiative to bring out your talent in the beginner mission, the first rating is something that Andrew can't interfere with with with the compass. However, a miss is a miss. As for now, Ren Di has never understood the productivity of the steam age so well.

The medal of the Evolution Battlefield has the effect of affecting a plane to converge the traces of time and space travel as much as possible. This is what every traversal system does, and evolution can do so while influencing a plane to the greatest extent. The medal is considered reasonable for intelligent beings in the plane being traversed. No longer in doubt. The impact efficiency of the Evolution Battlefield is the highest. And this has created a process that allows evolving officers to learn knowledge, accumulate knowledge, and participate in evolution.

Although Ren Di, who was born with a bomb pen, adopts the battle mode of a turtle, he will never give up any road that can blow up a pen. A tube-retreat howitzer with a range of six thousand meters caliber 105 mm. Field artillery with a range of 6,500 meters joined the army sequence of the Red Republican Army in northern Anhui. Ren Di's firepower era has arrived.

However, it was the matter of casting the cannon that made Ren Di's strategic development focus hesitate. Now that the armies of the Red Republican Army in northern Anhui were concentrated south of the Huai River and north of the Yangtze River, Ren Di was determined to completely bring Anhui Province, which occupied two-thirds of the province's land except for the south of the Yangtze River, into his sphere of influence. The following major battle is not surprisingly preparing to fight in the southern capital of the face. This kind of behavior of attacking the city and pulling out the fortress is to hit the face of the southern capital of the Ming Dynasty from the map.

Laying down the places between the Yangtze River and the Huai River in Anhui Province will have sufficient labor. and can get +1 pyrite. But on the other side of the Dabie Mountains, in the eastern part of Jing Province, next to the legs of the Red Republican Army, there are nickel mines in this place. A nickel mine in Jing Province is a chrome mine, which has not been developed for the time being. Because of the market demand, the Hai Song Dynasty, which occupies a vast colony, occupies South Africa where there are many chrome ores, and occupies the Nanyang Islands.

The inner wall of the barrel should be chrome-plated, and the barrel should preferably be made of nickel-chromium alloy steel. The most powerful armed force in this world is still Hai Song, and their energy Ren Di has never underestimated. Seventy years of accumulation, Haisong's material technology, scientific and technological heritage is profound. Zhao Weiguo, a second lieutenant who is ready to climb towards the steam age. Look up too.

The current Haisong is not short of money and population. What was lacking was the consciousness and union of the elders of the upper echelons. As early as the beginning of the establishment of the Senate, there were arguments among the senators over the system. One is biased towards a planned economy. One is biased towards the market economy. The patriarchs who had just come to this world found that this world was a virgin land where they could make money no matter what. You can make money by engaging in blackwater mercenaries, you can make money by engaging in breeding, and you can make money by engaging in commercial trade of running boats.

However, some can make money, some can't, everyone is not willing to make a big pot of rice on average, the reason is very simple, I can make money is my ability, I can't make money in this world are stupid, why should I use the money I earn to raise stupid. And you, the competent authorities, will charge a little more tax on my industry if you say a word of industrial support, and you don't bully people like this. Therefore, in order to ensure the production enthusiasm of the world's most advanced producers, the senators. So the policy began to favor the liberal economy. Of course, this first generation of patriarchs has a bit of a collective consciousness. When Hai Song needed to expand, all members could still compromise with each other for the development of the whole collective, and support the actions of the Hai Song government in terms of economic and policy coordination.

However, after the second generation of patriarchs came to power, the tacit understanding between the first generation of patriarchs was not passed on to this generation. The educational environment of the first generation of patriarchs is the educational environment of a large class of dozens of people, while most of the second-generation patriarchs have the same plane as the beautiful mushrooms of the Ming Dynasty. These Ming Dynasty mushrooms are good-looking, so you know! Not only was he influenced by his mother, but this wave of elders grew up in an environment where the natives of the surrounding plane were avoided. This is how the temperament of self-esteem is cultivated.

When these second-generation elders were in power, Hai Song basically had no enemies. There is no external oppression. Therefore, more attention is paid to controlling the interests of Hai Song. Increase the tax rate and enhance the country's development momentum. Most of the arguments here can be supported by a generation of elders who put forward a definite plan. But it doesn't make sense among the second-generation elders. I just want profits, that is, I don't raise wages for workers and raise the level of consumption. Lao Tzu is the patriarch, and the patriarch is free and equal to others. I don't want to give, how can you ask me for it.

As long as one patriarch is unwilling to back down, the other patriarchs are not willing to be fools who suffer losses. The political tacit understanding formed by their elders was broken in this way. A group of traversers from under socialism yearn for trust giant politics, because they have never been a trust giant at all, the political system created is full of holes, when they are still there, they can rely on the social habits developed by socialism to make up for it, but when they are not there, the deadlock in the political system is exposed.

Before Vinsted left this world, he had seen this sign, but he just didn't think about what he would become if he left. As soon as the elder was gone, the generation that the new generation of patriarchs was in awe of left. At the same time, it also put down its responsibility for the collective future of the Haisong country and paid more attention to the competition for interests.

For example, in the case of the outbreak of the Red Revolution in the Ming Dynasty, some of the veterans whose light industry sales were damaged asked to help the Ming Empire quickly stabilize the situation, while the overseas mining sector expected that it would be easy to immigrate, believing that there might be a large-scale refugee wave in the Ming Dynasty and that the labor cost of overseas workers would be greatly reduced, so they did not agree to immediately intervene. As for the machining of heavy industry, the arms trade awaits this war. As a farmer, the elders of the Hai Song Dynasty also need to reduce labor costs.

The elders of Hai Song are all civilized people, so there will be no scene of fighting on an island in the Ren Di plane, but the argument between the two sides is inevitable. The intervention of the Hai Song did not arrive at the first time, and the elders of the Hai Song Dynasty looked at the war on the East Asian continent and decided to continue to observe the development of the situation.

Daming bought a large amount of arms and food, and began to move south from the 80,000 imperial troops from the north to the south, and at the same time, Ren Di finally made a strategic decision. Hefei, a city in the central part of Anhui Province on the line of Shucheng, was marked by Ren Di in the red circle. 50,000 Red Republican troops, armed with 247 75 and 105 caliber guns, began the siege of the city.
