technical field
[0001] The invention patent belongs to the technical field of cold rolling of steel strips, and specifically relates to a cold rolling process of ultra-thin steel strips. Background technique
[0002] In recent years, the total output of my country's cold-rolled sheet has been increasing year by year, but its annual growth rate has shown a gradual slowdown. While the market demand is growing slowly, thin-gauge, high-strength sheets are increasingly favored by the majority of enterprises. The use of this thin-gauge raw material not only saves costs, but does not affect the performance, and can also make more and more beautiful packaging cans. This puts forward higher requirements for rolling equipment. At present, the rolling thickness of hot-rolled sheet can only be as low as 0.8~1.0mm. If you want to get thinner strip, you need to use cold rolling method. Using hot-rolled coils as raw materials, after a series of processes such as pickling, rolling mill, an...
