The development trend of heavy machinery in China
2018-11-13 11:02:15
The launch of the National Medium- and Long-Term Plan for Science and Technology Development and the publication of the State Council's Several Opinions on Strengthening the Revitalization of Equipment Manufacturing Industry have brought excellent opportunities for the development of the heavy machinery industry. In this great environment, increasing the research and development of technology, independent innovation, and achieving key breakthroughs are the development direction of the heavy machinery industry.
(1) Adopting “reorganization†measures to expand the scale of the enterprise economy
In order to enhance the company's ability to resist risks, in order to ensure that the company has sufficient funds to invest in innovation, the company must expand its scale. Currently, the most effective measures to expand the scale in China are the strong “reorganization†of state-owned enterprises, or the merger or reorganization of mergers. "Reorganization." Relocation and reorganization can not only expand the scale of the enterprise economy, but also diversify the capital of the enterprise, accelerate the adjustment of the product structure of the enterprise, and further promote the adjustment of the industrial structure. At present, the establishment of development bases in Dalian, Tianjin and other places is currently practicing the best form of expanding the scale of the enterprise economy.
(2) Based on heavy machinery, cross key points, and realize major adjustments in product structure and industrial structure of heavy machinery enterprises
For a long time, heavy machinery enterprises have provided large-scale and small-scale production of major technical equipment enterprises for the country and the society for a long time in the low-efficiency economic operation. At the same time, this situation has also created the potential technological innovation capability of heavy machinery enterprises. To this end, heavy machinery enterprises should also vigorously develop products with heavy mechanical features and batches, such as rolls and marine products that are mass-produced in batches, while maintaining a large number of small-scale batches of major technical equipment required by the country. In the field of combined crankshafts, too heavy into the field of large excavators, double-entry into the field of reducers required for wind turbines, CITIC heavy-duty machines enter the field of low-temperature waste heat power generation and so on. These will not only bring about major changes and improvements in the product structure and industrial restructuring of the enterprise as well as the economy, but will also have a major impact on the development of China's national economy.
(3) Technological breakthroughs in the heavy machinery industry
The heavy machinery manufacturing industry has made outstanding contributions to the development of China's steel, nonferrous metals, coal, petrochemical, building materials, electric railways and other basic industrial sectors and the promotion of international status. It is an underground nuclear test, aerospace launch, weapons industry, and automobile industry. The development of other departments such as water conservancy construction provides a large amount of technical equipment. In recent years, in order to meet the needs of the market, the competitiveness of enterprises in the metallurgical and energy industries has been enhanced. The new technologies, new processes and new equipment for the heavy machinery industry have been provided to the steel mills, mining and energy companies. A large number of large-scale complete sets of equipment with independent intellectual property rights also provided Pakistan with 300MW nuclear power plant pressure vessels.
In recent years, heavy machinery enterprises have developed heavy-duty technical equipment: Baosteel Phase II complete equipment (blast furnace, coke oven, sintering machine, 1900 slab continuous casting machine, 2050 hot rolling mill 2030 cold continuous rolling machine, system Oxygen machine, etc., Baosteel Phase III complete equipment "(1450 slab continuous casting machine, 1580 hot rolling mill, 1400, 1550 cold rolling mill, etc., Shougang Waterworks iron ore 10 million tons of open-pit mining equipment ( 10 cubic meters of electric shovel, 108 tons of electric wheel dump trucks, etc., Pingshuo coal mine 20 million tons of open-pit mining equipment can be 16 cubic meters of electric shovel, 23 cubic meters of electric shovel, 154 tons of electric wheel dump trucks, etc., Qinhuangdao three The four-day Hong Kong-Japan coal transportation package is not equipped with the 120-ton front beam production line equipment of the first automobile manufacturing plant, the world's largest 1200-ton bridge crane for the Three Gorges Project, the 1000-ton hydrogenation reactor for the petroleum cracking month, and 30 More than 20 major sets of large-scale castings and forgings required for Wanganwa, 600,000 kW thermal power generating units and Qinshan Nuclear Power Station are not available.
At present, heavy machinery enterprises represented by one weight and two weights have the ability to provide complete sets of equipment for the annual production of 6 million tons of steel joint ventures (including 4,350 cubic meters of blast furnace, 6 meters of coke oven, 450 square meters of sintering machine, Billet, round billet, slab continuous casting machine large-scale hot rolling mill, cold continuous rolling mill, seamless steel tube hot strip mill, high-speed wire mill, large plate mill and large spiral welded pipe unit, etc.) It provides an open-pit mine with an annual output of 20 million tons, an annual output of metal mines of 60-70 tons or less, an underground coal mine with an annual output of 5 million tons, and an annual processing capacity of 3 million tons of coal preparation plants. The annual processing capacity of a single series is 3 million tons. Grade concentrator, Nissan 4000-8000 ton clinker dry process cement complete sets of equipment can be equipped with 150-300,000 car parts forging production line and stamping production line, 50,000 cubic meters of particleboard production line complete sets of equipment, 30,000 cubic meters of medium density fiberboard production line complete sets of equipment Wait.
(4) Equipment requirements
The service focus of the heavy machinery industry has turned into the power industry. The demand for processing equipment includes heavy-duty vertical vehicles, five-axis machining machines, gantry milling machines with heavy-duty truck gantry widths of more than 6 meters, large gear processing equipment, and large crankshaft processing equipment. In addition, China's steel industry is developing rapidly. Rolls are a very expensive product in steel production. To produce 1 ton of steel, 5 kg of rolls are consumed, so there is a great demand for roll grinders. The processing of the brand (roller support) requires that the load capacity of the machine tool ranges from 200-300 tons up to 500 tons, requiring large gantry milling machines and large boring and milling machines. In short, the heavy machinery industry has a variety of CNC machines with good quality, large specifications, high power, large cutting force and large carrying capacity, and it is required to be delivered on time.
