Jiangnan Heavy Machinery Factory, which is directly under Jiangnan Heavy Industry, is a large-scale heavy industry R&D institution established by the original Jiangnan Machinery Bureau with the technical support of Beihai Shipyard.

On the same day, Qin Kai came here to participate in the ribbon-cutting mainly from the navy and air force, and what they wanted to witness was the commissioning of the first 4,000-ton ultra-large die forging hydraulic press in China, and the completion of this super-large material processing heavy machine will have a huge impact on the entire heavy industry in China.

Domestic steel production has grown amazingly in the past 20 years, and the current steel output has reached 17 million tons that were unimaginable in the early years, although it is still lower than the 25 million tons in the United States, but it has completely thrown off Germany and the United Kingdom. Fujian's foreign industrial base is almost zero, which is why it will give birth to the rapid growth of the four major heavy industries in the past two decades.

Nowadays, the domestic steel industry is not the era of the four major heavy industries under full control, although the industrial resources bill passed by the Congress makes the threshold for opening a large-scale steel industry in the country extremely high, with the strength of many domestic consortiums to accumulate wealth, capital is not an obstacle to entry at all, and technology is not an insurmountable problem, but the coal-iron complex is destined to have high energy consumption and high pollution, or it is difficult to solve the problem in this era.

However, the Beijing government allows overseas free ports around the South China Sea to invest in the steel industry, coupled with the discovery of huge high-quality iron ore areas in the Wende River Basin in North Australia, Palembang in Sumatra, Sulawesi Island in South China, and other places, more than a dozen large-scale private iron and steel plants have been formed, making full use of the resource advantages of overseas provinces to import products to the mainland.

However, Qin Kai naturally understands that the relationship between steel production and industrial power is not an equal sign, and the low-end steel smelting technology can never support the emerging industrial power, especially when the second wave of industrial ** wave of rapid technology sweeps the world, the core of industry will always be only two words - technology, and heavy machinery, as the country's heavy weapon, is a full reflection of the ability of technological competition at the national level.

The production and use of 5,000 tons of ultra-large die forging hydraulic press is the biggest benefit for the military that needs the most industrial technical support today, and the design requirements of naval guns, steam turbines, aircraft engines and even most of the military fields are undoubtedly very huge challenges compared with the industrial technology of this era.

Qin Kai naturally knows that although the www.biquge.info of hydraulic forging is very high, especially the difficulty of research and development and construction, but more importantly, it can improve the density of deformed materials through large pressure, long holding time, and slow deformation speed. It also has great efficiency across the era, especially the deformation uniformity of large integral forgings, high-temperature forging of complex structure forgings and other special processing technologies to meet the design requirements.

For most military generals, large-scale armament is naturally not a rare thing, but, compared to the stupid and coarse senses of battleships in this era, there is only one feeling when you see this giant die-forging hydraulic press, that is, rough ...... The entire hydraulic structure processing platform has a diameter of nearly 20 meters and a height of an astonishing 45 meters.

Qin Kai's cheap student Sun Xiang, wearing a black hard hat, happily greeted his long-lost teacher at the door of the factory, Qin Kai's identity as a student allowed him to gain a huge advantage in the deployment of R&D forces and the coordination of brother departments in Jiangnan Heavy Industry, and Qin Kai let him transfer from the Chemical Department of the Ministry of Industry to the administrative department, naturally he also wanted to make full use of his technical experience and contacts in the system to integrate these forces to tackle key technologies.

"Chairman, the early test machine has fully reached the standard, the unit pressure of 40NT design requirements, this time we crossed the heavy machine monomer construction 100 tons of mark, Jiangnan Iron and Steel Plant developed 70 components, other brother departments to assist in casting the rest of the components, the processing accuracy is perfect, the lifting in May was completed at one time!" Sun Xiang happily reported the results of the struggle.

Qin Kai nodded, and patted himself on the shoulder of this cheap student with emotion, from a teenager to an early gray man whose hair is now beyond his age, Sun Xiang followed him all the way, growing from an apprentice in Mawei to the organizer of a national heavy industry project, the hardships of this are naturally not something that can be expressed in a few words, but it is obvious that Sun Xiang enjoys such a life.

40NT, which means that this giant die forging hydraulic press has reached the 4400 ton level, and this steel processing technology, in Europe and the United States is still only in the field of research, the British monopoly on the production of large-caliber artillery Vickers company, Armstrong two giants, is still using a thousand-ton hydraulic press, and trying to break the pattern of the two Petersmore Iron and Steel Company, although it has a strong gun carriage production technology, but in the case of whether to invest heavily in the research and development of larger tonnage hydraulic presses and worries, otherwise there will be no possibility of competitive victory.

Compared with the hydraulic press, the Jiangnan factory research and development of this type of die forging hydraulic press has been the overall technology to another height, to create such a behemoth, need to consider a series of new problems such as material strength, structural deformation, installation adjustment and measurement correction, and the largest hydraulic press in China is the 2500-ton hydraulic press developed by Mawei Heavy Industry, which is used for the construction of the 343mm main gun of the Mawei Artillery Factory.

The construction of larger heavy machinery, by no means a simple proportional enlargement, but, once completed, will have an immeasurable value to the entire country's industry, the Navy 05II marine steam turbine turbine disk technology, large-caliber main gun technology will stand on a new pen fun pavilion www.biquge.info, even if there is only one, this will still be the treasure of the industry.

The accompanying military generals actually did not have much interest in today's ribbon-cutting ceremony, and after Qin Kai was introduced to the main control room by Sun Xiang, he immediately pulled the engineers of Jiangnan Heavy Industry who were in charge of receiving them that day to ask questions about processing technology, and their questions were almost all focused on marine steam turbines and diesel engines.

To bear the harsh working conditions of high temperature, high pressure and high-speed rotation, so the material is tough and resistant to high temperature, especially when these machinery enters the era of large-scale, it has brought huge manufacturing problems that cannot be overcome by conventional industries, and this plan proposed and implemented by Jiangnan Heavy Industry has finally provided a possibility for the military to provide a possibility to solve the problem that has been troubled.

The ribbon-cutting event was very simple, but Qin Kai brought the commendation order of the National Science and Technology Development Committee, and personally awarded the national gold and silver medals to the 35 awardees, and at the same time, these technicians who made outstanding contributions to the national heavy industry received a bonus that was enough to show their achievements.

Later, Qin Kai personally convened a meeting of the core engineers of the R&D team of the super-large die forging hydraulic press, and he made a decision that surprised everyone - in addition to preparing for the 80NT level die forging hydraulic press design team is expected, the Ministry of Industry will immediately fund the implementation of a new plan, in the four major heavy industries to build 10 die forging hydraulic press equipment slightly smaller than Jiangnan Heavy Industry, and the team of Jiangnan Heavy Industry needs to provide a full range of technical support for this plan.

Later, Sun Xiang was obviously a little confused and whispered his doubts to Qin Kai, after all, to carry out the research and development of 80NT giant die forging hydraulic press, this is not a simple project that can be done by doubling the size of the machine parts, but an almost completely new design, each casting needs to be fully designed to ensure that the whole machine is not crushed by its own weight, and now a large number of core technical personnel are divided to guide other heavy industries to build smaller die forging hydraulic presses, obviously not to carry out technology diffusion......

"Sun Xiang, what we urgently need at present is the increase in the production capacity of heavy industry, of course, the technical team of cutting-edge heavy industry I will still ensure sufficient research funds, but in the current situation, it is not a top priority, you must coordinate this heavy project!" Qin Kai confirmed this plan with a stern expression.

Giant die forging hydraulic press is naturally the country's heavy weapon, however, small and medium-sized die forging hydraulic press will provide sufficient production capacity for major factories, after all, it is impossible for all materials to be processed by Jiangnan Heavy Industry, especially in the coming world changes, once the war starts, the country needs a huge production capacity, rather than a small number of high-precision and cutting-edge products.

On August 3, when Qin Kai arrived at Mawei Port in Fuzhou on the Navy supply ship Wangjiaxi, an urgent telegram from the Beijing Military and Political Department brought news that made him stunned...... The powder keg of the Balkans looks like it really has been ignited! R1152
