Development of underground space birth tunneling equipment industry

The industry to address population growth, rational use of resources and protecting the environment and the rise of such issues. Countries in the world are increasing emphasis on the development and utilization of underground space, the underground space as a new type of land and resources, and called it "underground industry", the experts predicted that "The 21st century is the century of development and utilization of underground space."

While developed countries have a certain scale underground space development and utilization of, but it is far failed to meet the requirements and the development of China is just beginning. China Heavy Machinery Industry Association, Wang Chien-yeh said that China now has basically have the economic and technological strength of a large-scale development of underground space of capacity, a large number of underground space development of the timing of the beginning, therefore, the development of underground space as the main equipment - TBM machines will be very good, focus on the development of large modern tunnel boring equipment is very necessary, and the market prospect is broad. Formerly a long-term dependence on imports of large boring machine, each (sets) the cost of imports about 30 million U.S. dollars, preliminary projections of future If you're still dependent on imports cost 1.1 billion U.S. dollars each year. Can be seen the development of tunneling machine industry is imperative.

Ke Shi, general manager of the Second Heavy Machinery Group, introduced the company's partnership with the United States Robbins TBM manufactured ?3.65 meters into the day footage of Yunnan, 80 meters of construction to achieve the target, which will no doubt have our boring machine Localization a great deal of pushing forward.

To achieve localization of mining equipment

2010, China's coal output will reach 18 million tons, the existing Shenhua, Yanzhou, Datong, Jincheng, Zibo mine needs by 2010, a total of more than 1200kW high yield of fully mechanized mining equipment, 55 sets of electric traction. Taking into account factors such as new construction and renovation coal mine, then the fully mechanized mining demand for electric traction equipment, more than 100 pieces (sets).

According to statistics, the introduction of a fully mechanized mining Shenhua electric traction equipment, would need 30 million -4000 million U.S. dollars, the introduction of 100 sets of the cost about 40 billion U.S. dollars. This is not only the use of a large number of foreign countries, but also coal become unbearable. At present, Taiyuan Mining Machinery Group has been developed with the international advanced level of 1200kW of the kinds of models, which shows that our mining equipment in mines and tunnels on the research and development of a new dynamic.

The coal industry enterprises have been called for the development of China's own high-yield and efficient coal technologies and equipment, and this is the inevitable trend of development of the coal industry, mining technology and equipment to achieve localization is also China's accession to WTO, the urgent requirement.

Metallurgical equipment industry development potential is not small

Development in the metallurgical equipment, China has made significant progress. 1st Heavy Machinery Corporation and Anshan Iron and Steel Group have completed the 1700 sets of continuous casting and rolling equipment is completion of this period, domestic-based representative of the complete sets of equipment, the end of hot rolling entirely dependent on foreign technology in history.

China in the next 5-8 years, steel products should increase the plate, belt, tube output and the quality of the equipment has a continuous and large-scale and automation requirements. Heavy equipment manufacturing for the metallurgical industry in 2002 total output value of the equipment provided by the industry output value accounted for 12% or so. Last year 869 million U.S. dollars of imports of metallurgical equipment, accounting for nearly half of metallurgical equipment market for foreign enterprises to occupy. Therefore, the focus on the development of metallurgical equipment industry imminent.

Large circulation activated material handling equipment industry

As long as there is production, consumption and circulation, it is inseparable from material handling machinery. In Japan, for the material handling cost of about 10.7% of the cost of production; the United States and Germany account for about 11% of the total cost of -13%; China has accounted for 18% -21%. Therefore, the increase of mechanization and automation of our material handling room for development is great.

At present, Dalian Heavy Industry Group Co., Ltd design and manufacture of lifting the 2250t / h ship unloader, fixed rotary arm overhead traveling crane, etc., have reached a large lifting equipment manufacturing in China a new record. Shanghai Zhenhua Port Machinery shares of the company's large-scale container crane products abroad and occupied most of the international market.

Wang, chairman pointed out that in the future should focus on the development of material handling equipment, port handling loading and unloading of large container complete sets of equipment, mines, docks loading and unloading of bulk material transportation system complete sets of equipment, large-scale automated storage and handling three-dimensional large-scale automation of complete sets of equipment and city parking facilities.

Three industry needs a large forging and stamping equipment

At present, the development of large forging capacity of equipment has a new increase. Xi'an Heavy Machinery Research Institute from the total and is headed by Shanghai Heavy Machinery Plant produced 10,000 tons of the world's first double-action aluminum extrusion unit into operation in Shandong jungle groups and has begun to Germany, France and other European countries export a large aluminum extrusion products.

Experts believe that in the next decade, there are three key industries require large-scale forging equipment. First, the city buried underground overhead power plant renovation and construction needs large-scale extrusion and forging equipment production of large non-ferrous and plastic pipe, board and other products; second is the development needs of automotive structural parts stamping production lines and precision forging, precision the entire production line; three development needs of the aviation industry, large-scale forging equipment.

Heavy Casting and Forging the annual demand will reach 100 thousand tons

The production capacity of China's large-scale Casting and Forging a 5 million tons, need to be imported from abroad generator rotor. A weight, two weight were required for the successful development of large-scale Three Gorges turbine blades, making foreign investors enter the Chinese market this product prohibitive. By 2020, China's annual needs of about 100,000 tons of large castings and forgings to supply industrial development in the important industry.

Their supply projects are: the Three Gorges need 18 sets of 70????turbine group of about 100 thousand tons of large Casting and Forging; large-scale cold and hot rolling mill equipment for rolling mills, a large arch and roll; chemical industry development to take tons of hydrogenation 800-1200 Reactor; thermal power is needed annually for 5-8 sets of 300,000 -60 kw machine large-scale Casting and Forging; 6.7 million kilowatts of nuclear power plants also need large-scale Casting and Forging a year.
