General knowledge of forged steel roll

2022-01-15 17:31

The roll manufacturer said that after smelting, forging and heat treatment, the forged steel roll makes the working layer of the roll body have uniform, high hardness, high wear resistance and excellent anti accident ability, so as to ensure that the roll neck and roll body core have certain strength and high resistance. Today, let the roll manufacturer Wuxi Taihu roll editor bring you a brief introduction to the general knowledge of roll forged steel roll.




This unique function of forged steel roll makes it have the advantage that cast roll can not be replaced in cold rolling and nonferrous rolling.

According to the application conditions, forged steel roll can be divided into forged steel hot roll and forged steel cold roll. Forged steel hot roll is mainly used for hot rolling billet and section steel coarse roll, and forged steel cold roll is widely used for cold roll. The application requirements of forged steel cold roll are high. It is necessary to have high and uniform hardness on the surface of the roll body to ensure the dimensional accuracy and excellent appearance quality of cold-rolled strip or steel plate. The roll body has a certain hardening layer depth and high anti incident ability. Therefore, the original arrangement requirements of the roll are very strict, one is the pure metallurgical quality, and the other is the uniformity of the arrangement. At present, China mainly uses the cold roll raw materials containing about 2% chromium, and the working layer above hs90 is about 10mm, while the newly developed Cr5 series cold roll containing 5% chromium, and the working layer above hs90 is more than 30mm. The performance of Cr 5 Series cold rolling working roll is better in all aspects, which will gradually replace the traditional CR 2 series cold roll and become the development direction of cold rolling working roll.




Roll is the main working part and thing that causes continuous plastic deformation of metal on the rolling mill. The roll is mainly composed of roll body, roll neck and shaft head. The roll body is the middle part of the roll that is actually involved in rolling metal. It has a smooth cylindrical or grooved appearance. The roll neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and screwdown equipment. The shaft head at the transmission end is connected with the gear seat through the connecting shaft to transmit the rolling torque of the motor to the roll. Rolls can be placed in the form of two, three, four or more rolls in the mill frame.
