SS400 hot rolled structural steel plate production process mainly includes smelting, continuous casting, rolling and other links. The main production process is as follows:

1. Smelting: the use of electric furnace or converter steel smelting, adding the appropriate amount of alloying elements to adjust the mechanical properties and processing performance of steel.

2. Continuous casting: the steel obtained from smelting is poured into the continuous casting machine for solidification, forming billets.

3. Rolling: the billet will be sent to the rolling mill for rolling, to get different specifications of the steel plate. In the rolling process, the need to control the temperature, speed and other parameters to ensure that the mechanical properties of the steel plate and processing performance.

4. Surface treatment: the rolling of the steel plate for surface treatment, such as descaling, painting, etc., in order to improve the corrosion resistance and service life of the steel plate.
