Raw Material : the raw material steel plate or molten steel is poured into the coil loader, and the steel plate or molten steel is cut into a suitable size and rolled coil through mechanical equipment
Pickling: Put the master roll into the pickling tank, and remove impurities such as oxidation, rust and grease on the surface through the pickling liquid to make the surface of the steel plate smooth and clean

It is mainly billet or round steel, and the quality of raw materials is tested to ensure that it meets the production requirements, and then the raw materials are cut, trimmed and the surface defects are removed to ensure that the quality and size of raw materials meet the requirements

Preparation of raw materials
The raw materials of steel plates are mainly iron ore, scrap steel and alloying elements,The blast furnace method, iron ore, coke, and limestone layer by layer, after reduction, melting and reaction, finally get molten iron
