the launch and implementation of the outline of the national medium and long term scientific and technological development plan The release of the few opinions of the State Council on the revitalization of the equipment manufacturing industry has brought great opportunities for the great development of the heavy machinery industry. In this good environment, the development direction of the heavy machinery industry is to strengthen technological research and development, independent innovation and achieve key leaps.

(1) adopt "restructuring" Measures to expand the economic scale of enterprises in order to enhance the anti risk ability of enterprises and ensure that enterprises have enough funds to invest in the construction of innovation ability, enterprises must expand their scale. At present, the most effective measure to expand the scale in China is the "reorganization" of state-owned enterprises, or the "reorganization" of mergers and acquisitions or the "reorganization" of relocation. Relocation and reorganization can not only expand the economic scale of enterprises, but also realize the diversification of enterprise capital, accelerate the adjustment of enterprise product structure, and promote the adjustment of industrial structure. At present, Yizhong has established development bases in Dalian, Tianjin and other places, and is practicing this best form of expanding the economic scale of enterprises. At present

(2) based on heavy machinery, the road is more focused, and the product structure and industrial structure of heavy machinery enterprises have been significantly adjusted

heavy machinery enterprises have long been in the economic operation of low efficiency for enterprises that provide single piece and small batch production for the country and society. At the same time, this situation has also created the potential technological innovation ability of heavy machinery enterprises. For this reason, while maintaining its single piece and small batch supply of major technical equipment required by the country, heavy machinery enterprises should also vigorously develop products with heavy machinery characteristics and batch production, such as the first heavy machinery into the field of mass-produced rollers and marine combined crankshafts, the second heavy machinery into the field of large excavators, the second heavy machinery into the field of noisy machines required by wind turbines, the second heavy machinery into the field of low-temperature waste heat power generation, and so on. These will not only bring significant changes and improvements to the enterprise production structure and industrial structure adjustment to develop the economy, but also have a significant impact on the development of China's national economy

3 technological breakthroughs in the heavy machinery industry

the heavy machinery manufacturing industry has made great contributions to the development of China's basic industrial sectors such as iron and steel, nonferrous metals, coal, petrochemical industry, building materials, electric power railway and the improvement of its international status. It has provided a large number of technical equipment for the development of other sectors such as underground nuclear testing, space launch, weapon industry, automobile industry, water conservancy construction and so on. In recent years, in order to meet the needs of the market and improve the competitiveness of enterprises in metallurgy, energy and other industries In the first half of the year, the transformation enterprises of new technologies, new processes and new equipment in the heavy machinery industry made a main business profit of 42.819 billion yuan. The backward processes and equipment provided a large number of large-scale complete sets of equipment with independent intellectual property rights to steel mills, mining and energy enterprises, and also provided 300MW Nuclear Power Plant pressure vessels to Pakistan

in recent years, heavy machinery enterprises have developed and completed heavy-duty technology and equipment: Baosteel Phase II complete sets of equipment (blast furnace, coke oven, sintering machine, 1900 slab caster, 2050 hot strip mill, 2030 Cold Strip Mill, oxygen generator, etc.), Baosteel Phase III complete equipment "(1450 slab caster, 1580 hot continuous rolling mill, 1400, 1550 cold continuous rolling mill, etc., and 10million ton open-pit mining complete equipment of Shougang Shuichang Iron Mine (10 cubic meters of electric shovels, 108 tons of electric wheel dump trucks, etc.. Pingshuo Coal Mine 20million tons of open-pit mining equipment can be 16 cubic meters of electric shovels, 23 cubic meters of electric shovels, 154 tons of electric wheel dump trucks, etc., Qinhuangdao phase III, Siming port and Japan coal transportation complete sets are not equipped with 1200 tons of front beam production line equipment of the first automobile manufacturing plant, the world's largest 1200 tons of bridge cranes for the Three Gorges project, 1000 tons of hydrogenation reactors in the month of oil cracking, and 300000 dry tiles More than 20 major complete sets of castings and forgings for 600000 kW thermal power generating units and Qinshan nuclear power station are not available

at present, heavy machinery enterprises represented by the first and second heavy industries have the ability to provide complete sets of equipment with an annual output of 6million tons of conventional processes for iron and Steel Complex Enterprises (including 4350 cubic meters of blast furnace, 6 meters of coke oven, 450 square meters of sintering machine, square billet, round billet, slab caster, large-scale hot continuous rolling mill, cold continuous rolling mill, seamless steel pipe hot continuous rolling mill, high-speed wire rod mill, large-scale medium thick rice mill, large-scale spiral welded pipe mill and other complete sets of equipment), Provide an annual output of 20million tons of open-pit mines, annual output of metal mines below tons, annual output of 5million tons of underground coal mines, annual processing such as 3million tons of coal preparation plant, a single series of annual processing capacity of 3million tons of beneficiation plant, daily output of tons of clinker dry process cement, a wide range of equipment, which can be equipped with 10000 car parts forging production lines and stamping production lines, 50000 cubic meters of particleboard production line complete sets of equipment Complete sets of equipment for 30000 cubic meters medium density fiberboard production line, etc

4 equipment demand

the service focus of the heavy machinery industry has shifted to the power industry. The demand for processing equipment includes heavy vertical lathe, five axis processing machine tool, gantry boring and milling machine with gantry width of more than 6 meters of heavy sleeper, large gear processing equipment, and large crankshaft processing equipment. In addition, China's steel industry is developing rapidly Roll is a product with large consumption in steel production. 5kg roll is required to produce 1 ton of steel, so there is a great demand for roll grinder. The processing of licensing (roll support) requires the bearing capacity of the machine tool to be up to 500 tons, and requires large gantry milling machines and large boring and milling machines. In short, all kinds of CNC machine tools with good quality, large specifications, high power, large cutting force and large bearing capacity in the heavy machinery industry are required to be delivered on time
