Cold rolled production have been developed from the 20's, 30's to 40's America develops rapidly, has been developed in the world, and the development of soybean 60, 70's cold rolling production and technology make a spurt of progress is to achieve the degree of.

Cold rolled wide. Automobile, tractor, electric products, vehicles, shipbuilding, aerospace, precision instrument, anti rocket civil construction, industrial building, household appliances, food cans and durable products need is the cold rolled plate. Due to the development of the industry, more high quality requirements more and on the sheet, production requirements more and more big, the cold rolling strip production put forward higher requirements, so the cold rolled sheet, strip steel production growth is very fast.

Cold rolling plate and strip products mainly include: carbon steel, alloy steel and low alloy steel plate, stainless steel plate, electric fans and other special steel plate, in addition, there are tin, zinc, composite steel plate, composite coating. Cold rolled strip is not only a wide variety of specifications, and a wide range of. Because of the importance of cold rolled products development of cold-rolled plate production is very necessary. It can be said, today the cold rolled sheet production and comprehensive utilization of the latest achievements in modern metallurgical, mechanical, electrical, chemical, auto control, and the ability to become the strongest in the cold rolling mill, the highest efficiency, the production process mechanization and automation level of the most advanced factories, steel rolling production is developing towards the modernization of the pioneer.
