Semi-steel rolls

Semi-steel rolls are a type of roll that is commonly used in the rolling process of metal materials. It is mainly composed of two parts: the roller body and the bearing. Rolls are typically made of high-strength alloy cast iron or cast steel to withstand high pressure and high temperature working conditions.

Semi-steel rolls play a key role in both hot and cold rolling processes. Hot rolling refers to the rolling of metal blanks after heating to high temperatures, which is used to produce steel plates, steel strips and other products. Cold rolling refers to the rolling of metal sheets at room temperature, which is used to produce cold-rolled steel plates, sheets and other products.
