One is the steel mill in the production of stainless steel rolling through the rolling mill, the main thickness of these products in the 3-6mm or so, is hot-rolled after the state of acid wash, the process is as follows:
Stainless steel billet → hot rolling mill rolling black roll → hot annealing and pickling line → leveling machine, straightening machine, polishing line → cross-cutting line → hot-rolled stainless steel tread plate
This pattern is flat side, the other side is the pattern. Such stainless steel tread plate is more commonly used in chemical, railway vehicles, platforms and other requirements of the strength of the occasion. Such products to import mainly from Japan and Belgium, the domestic production of TISCO and Baosteel belong to this type.
