The manufacturing level of the hottest heavy machi

  • Detail

The manufacturing level of heavy machinery has reached the world advanced

as an important part of the machinery industry, heavy machinery mainly provides technical equipment and large castings and forgings and other basic equipment for basic industries such as energy development, raw material production, transportation and national defense industry, and plays an important role in national economic construction. Since 1978, China's heavy machinery industry has entered a new stage of historical development from the initial stage of forming a manufacturing force. The output of heavy machinery products in China was only 490000 tons in 1977, and reached 7.3 million tons in 2007. In 1980, the total output value of China's heavy machinery industry was 2.25 billion yuan. Such materials can be used as substitutes for glass and carbon fiber reinforced plastics. In 2007, the total industrial output value reached 369.031 billion yuan, 163 times that of 1980. In recent years, China's heavy machinery industry has developed rapidly with an annual growth rate of more than 30%

in the past 30 years of reform and opening up, the products of China's heavy machinery industry have developed from meeting general domestic needs to reaching or leading the foreign advanced level. In 2007, we improved the green credit mechanism, and the total export volume of China's heavy machinery products reached US $8.773 billion. The research and development capacity of large-scale forging equipment has reached the world's advanced level. The low-temperature waste heat power generation equipment of CITIC Heavy Industry Machinery Co., Ltd., the world's largest 55 cubic meter mining excavator independently developed and produced by Taiyuan Heavy Machinery Group, and the 1700 continuous casting and rolling complete equipment jointly completed by the first heavy machinery group and Anshan Iron and steel group have ended the history of relying on foreign technology, indicating that China's heavy machinery industry has developed rapidly through the insurance compensation mechanism. The picture shows the 16000 ton hydraulic press, the world's largest 10000 ton hydraulic press developed by the second heavy machinery group company. It has successfully forged the support roll of the 4100 mill of Chongqing Iron and Steel Co., Ltd., which weighs 340 tons of steel ingots
