Precision straightening work rolls are mainly used for straightening high quality or precision strips and are used in precision multi-roll straightening machines. Precision straightening rolls have extremely high requirements for work roll surface accuracy and roughness, which places higher demands on the product processing and manufacturing capabilities, and process control. Precision straightening work rolls are mainly used for the straightening of stainless steel and tinned plates.
During the production of strip, all kinds of plates need to be straightened by leveling machine after they are rolled to the size of finished products to ensure their flatness. Generally speaking, the thinner the plate, the smaller the diameter of the work roll, and the quantity of the rolls will be more. Straightening roller, although the force is not large, but because of its small diameter, long length, length-diameter ratio, processing accuracy and hardness uniformity requirements are very high. High requirements for turning, grinding and heat treatment.
At present, BOYA slender roller can reach the length diameter ratio of more than 90.
