Domestic heavy industrial equipment breakthrough

Equipment manufacturing industry is a basic industry that provides technical equipment for the development of national economy and national defense construction. After more than 50 years of development, China's equipment manufacturing industry has made remarkable achievements, formed an industrial system with complete categories, a considerable scale and a certain level, and has become an important pillar industry for China's economic development. However, there are also problems such as weak independent innovation capability, high external dependence, unreasonable industrial structure, and weak international competitiveness. Seriously restricting our country to take a new road to industrialization and achieve sustainable development of the national economy.

China is known as a world-famous manufacturing country, but the major equipment needed each year is dependent on imports. In recent years, many new automobile production lines have been built in the country. A large number of stamping equipments, painting equipments, testing equipments, welding robots and even the entire assembly line are imported from abroad. Among the 16 key development projects proposed by the country, the first is large-scale clean and high-efficiency power generation equipment, including millions of kilowatt-class nuclear power units, ultra-supercritical thermal power units, etc. Currently, only the United States has 3. The 150,000-ton extruding unit, together with Germany's Mannesmann Company and Sumitomo Corp. of Japan, almost monopolized all the world's high-temperature high-pressure and thick-walled molding materials. The large-caliber thick-walled seamless steel pipes required for high-power power generation equipment in China basically need to be imported.

The manufacture of 10,000-ton heavy equipment is a sign of a country’s manufacturing capabilities, involving many technical difficulties in design, manufacture, transportation, installation, and so on, and it belongs to the field of “extreme manufacturing”. This time, following the breakthrough of 36,000 tons of heavy vertical extrusion press in China, the world’s first 50,000-ton vertical hot-squeezed steel pipe unit has been applied to large-diameter thick-walled, high-alloyed and stainless steels, titanium alloys, and nickel-base. The production of high-pressured, thick-walled seamless steel tubes, such as alloys, is aimed at solving high-grade, high-value-added products that cannot be completed with special applications, alternative imports, and scarcity, and can be manufactured using large-diameter thick-walled seamless steel tubes. Major breakthroughs in technology and industrialized production have raised the level of localization. The 10,000-ton level vertical extrusion machine belongs to the high-end manufacturing field and is a symbol of a country's manufacturing capability.

The independently designed and manufactured 50,000-ton vertical hot-extrusion steel pipe hydraulic press has its own intellectual property rights, all of which are manufactured in China. It has achieved technological breakthroughs in many aspects and has created many world firsts. The fatigue life of the main bearing parts of the press; the second is the design and manufacture of the rod-type composite beam, reducing the single weight of the parts and the difficulty of manufacture and installation; the third is the design of the ultra-high pressure system to enhance the stability of the equipment; the fourth is the large-scale hot work mold. Hot billet - vertical extrusion process technology. After the mass production of the 50,000-ton vertical extrusion machine project, only replacing the import each year will save the country 500 million U.S. dollars.

It is believed that after a series of breakthroughs have been made in heavy vertical extrusion machines, China’s ultra-large-scale equipment manufacturing industry will develop very quickly and will no longer be controlled by some important production equipment in order to devote more resources to Other unconquered ones. Under the technical problem, to achieve a linear breakthrough.
