DD11(StW22) Process Features
With hydrochloric acid and iron oxide on hot rolled steel sheet after clearing get a nice, smooth surface. After formation, the surface of the steel sheet tends to be more cold-rolled plate surface.
By pickling the steel sheet surface oxide scale, so that the steel sheet surface defects easily exposed, so the main problem is to ensure a high quality surface production process control should be considered.
