After entering the 21st century, China's aluminum processing industry has achieved rapid development. The hot-rolling equipment has been independently developed in 2002. The first single-stand double-coil 4-roller reversing hot rolling mill was put into operation at the Yunzhou Xiezhou Aluminum Plant. The aluminum strip with a single-stand double-rolling 4-roll reversible hot rolling was set up in China. The construction of hot rolling production line has culminated, and more than 20 single-stand double-coil hot rolling production lines have been built. It is estimated that by 2015, China's aluminum alloy plate production capacity will be more than three times the world's total demand. Domestic cold-rolling equipment has developed rapidly. In the aspect of cold continuous rolling, there are 4 production lines for cold rolling in China by the end of 2011, including Shanghai Sapa 1700mm domestic cold continuous rolling and Southwest aluminum 2000mm imported cold continuous rolling. The characteristics of high production efficiency and low unit output cost are the preferred choices of domestic enterprises in recent years, and the potential market demand is large.
In general, China's aluminum sheet and foil rolling equipment is developing in the direction of wide, high speed, high precision and high intelligence. The construction and production of these production lines have introduced a large number of foreign advanced equipment on the one hand, some of the production equipment has reached or approached the international advanced level, and on the basis of digesting and absorbing imported technology and equipment, researching and developing new technologies on its own, making aluminum strips The material technology equipment has been updated and upgraded; on the other hand, in recent years, a large number of large-scale integrated aluminum sheet and foil enterprises with a capacity of 100,000 to 500,000 t/a have been formed, and the production capacity of aluminum foil and foil in China has been improved. Relevant information only from 2010 to 2012 production of aluminum foil of 70 projects, producing intervals can be formed about 8337kt / a, which is unique in the history of the world's aluminum. Due to the huge capacity currently under construction, preparation and planning, the risk of overcapacity in the aluminum sheet and foil processing industry is increasing in the future.
