The production process of ASTM A36 Steel Plate ASTM A36 Steel Sheet

The application of ASTM A36 Steel Plate ASTM A36 Steel Sheet in our life has been very extensive. Everyone is familiar with its operation method, but I believe that many friends do not know much about its production process. In fact, its production process is mainly It is divided into rough rolling, finishing rolling, annealing, pickling, and cold rolling and so on.

1. Rough rolling

The ASTM A36 Steel Plate ASTM A36 Steel Sheet is rolled to a slab of a certain thickness and width by a roughing mill at a higher temperature. Generally, the roughing mill is a four-high rolling mill.

2. Finishing rolling

The stainless steel slab rolled by the roughing mill is sent to the finishing mill through the rolling line guide, and rolled into the required thickness and width of the plate. Generally, coil rolling mills or continuous rolling mills are used for rolling.

3. Annealing

Heating steel or steel products to a certain temperature and keeping it for a certain period of time, slowly cooling to room temperature, the rolled stainless steel plate has certain processing stress or structural defects, and annealing in an annealing furnace can improve the structural defects and eliminate stress.

4. Pickling

Remove the oxide scale on the surface of ASTM A36 Steel Plate ASTM A36 Steel Sheet and passivate the surface.

5. Cold rolling

In order to obtain better flatness and thinner stainless steel plates, hot-rolled pickled stainless steel plates are rolled at room temperature. Generally, a 20-high rolling mill unit is used.
