Comparing to other countries, the cold rolling strip production mills are started and developed a little late in China.
The begining of cold rolled steel coil productionin China is at 1961, Angang steel built the first cold rolled strip mill with the engineering and design from soviet union. It start the history of colded rolled coil production line in China. Then , Taiyuan steel imported the 8 rollers and 20 rollers cold rolling mills.
Before 1978, no matter Angang steel or Taiyuan steel, their cold coil production line both were in low effeciency, low quality and low capacity. They were fall behind to the level of the world in technology at that time. In 1978, Wugang steel imported the 1700 cold rolling mills and referenced patents from Germany, this production line was at the advanced level at that time, brought a lot of technology and engineering experienced to China.
After that, more and more advanced cold rolled strip lines are imported, invented and updated in China market, many cold rolled strip mills were installed all over the China, and made a very important contribution to the china steel development.
Now chinese company not only can produce the high level cold rolled steel coils, we also can supply the cold rolled coil production lines to other countries to help them.Tianzhongzhongzhi will persist in the business ethic of technology as guide, product as cock, quality as guarantee, service as foundation.With innovative design concept.sincere enthusiastic attitude, enterprising spirit, honest reputation, spirit of team cooperation , we keep up with the latest frontier of metallurgical technology and provide customers with the best products and services.
