Factory Cheap Hot Rolling Mill Rolls - Rolls – Runxiang

It has a smooth cylindrical or grooved surface.

The roll neck is installed in the bearing and the rolling force is transmitted to the frame through the bearing housing and the press-down device.

The shaft head of the transmission end is connected with the gear base through the connecting shaft,and the rotation moment of the motor is transferred to the roll.

The rolls can be arranged in the form of two,three,four or more rolls in the mill frame.

1.What is a roll and what are the types of mill roll?

The overall roll is divided into two kinds of overall casting and overall forging rolls. Metallurgical composite casting rolls mainly have semi-flushing composite casting, overflow (full flushing method) composite casting, centrifugal composite casting three, in addition to continuous casting cladding, jet deposition method, hot isostatic pressure, electroslag welding and other special composite methods of manufacturing composite roll types.
