Industrial Back-Up Rolls
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?
Roll is a tool to make (rolled material) metal plastic deformation, is an important consumption parts to determine the efficiency of the mill and the quality of rolled material. Roll types can be divided into casting rolls and forging rolls according to the forming method; divided into integral rolls, metallurgical composite rolls and combined rolls according to the process method. 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. Combination rolls are mainly set combination rolls.
2.What is integral roll?
The outer layer of the roll body and the heart and the neck of the roll body are made of single material casting or forging, and the different organization and performance of the outer layer of the roll body and the neck are controlled and adjusted by the casting or forging process and the heat treatment process. Forged rolls and static casting rolls are all integral rolls.
3.What are the main categories of rolls according to the material?
The rolls are mainly divided into three categories of cast steel series rolls, cast iron series rolls and forged series rolls according to the manufacturing materials.
4.What are casting rolls and what are the main types of casting rolls?
Casting rolls are the types of rolls manufactured by the production method of direct casting of smelting steel or molten iron. According to the material, casting rolls can be divided into two categories: cast steel rolls and cast iron rolls; according to the manufacturing method, they can be divided into two categories: overall casting rolls and composite casting rolls.
