How to solve the problems of SS400 hot rolled sheet surface
At present, one of the problems of further improving the quality of SS400 hot rolled sheet is the surface quality problem, especially when the SS400 hot rolled sheet is directly applied to the outer surfaces of structural parts. For example, the outer overlay of a car has put forward more stringent requirements for SS400 hot rolled sheet surface quality and quantity.
The surface pitting defect of SS400 hot rolled sheet is caused by the surface defect of work roll. The surface defect of SS400 hot rolled sheet caused by rolling iron sheet is related to the chemical composition of the SS400 hot rolled sheet.
Adding a small amount of Si into Al-killed steel can obviously reduce the surface defects of SS400 hot rolled sheet. When the content of Si exceeds 0.05%, the 2FeO SiO2 layer formed on the SS400 hot rolled sheet surface plays an important role in preventing the oxidation of SS400 hot rolled sheet.
