The mill si a four-high hot rolling mill. The project is on the design of the Mill Housing. According to the rolling type and job requirements and different structure,mill Housing frame is divided into two kinds of closed and open.Mill Housing is one of the important components which is used for installing the whole system of Roll,the device which regulates Mill Roll and supporting all of rolling pressure. Mill Housing has been designed the perp
