Manufacturing Technology

1. Steelmaking: Electric furnace or converter steelmaking is used to melt raw materials such as iron ore and scrap steel into molten steel.

2. Rolling: Pour the refined steel into a rolling mill and roll the steel billet into the desired thickness and width through the rolling process.

3. Heat treatment: Heating and cooling treatment is applied to the rolled steel plate to obtain the required mechanical properties.

4. Surface treatment: Polishing, coating and other treatments are applied to the surface of steel plates to improve their corrosion resistance and service life.
