Product Description

The rolling mill roller is an important part of the rolling mill. According to the type of rolling mill, it can be divided into strip rolling mill, section rolling mill and steel tube rolling mill. The roll body of the strip mill is cylindrical, and the roll body of the hot strip mill is slightly concave. 

Roll the choice of materials and work characteristics and damage roll form are closely related.

Steel mill roll and have a larger impact force load, should have sufficient strength and hardness of the roll surface can be placed on second.

Roughing mill roll should be chosen by special soft annealed pearlite ductile iron rolls, the hardness should be lower, usually select the hardness HS38 ~ 42. If the resistance is a major problem, then select slightly higher hardness of the HS45 ~ HS48 more appropriate.

Group selected in the rolling mill roll mill set the hardness to be thicker high, the hardness value of up to HS67, material to pearlite or bainite ductile cast iron as well. If the needle used centrifugal casting ductile iron roll the best. The intermediate rolling mill group in the practical effect of high-chromium roll better.

Finishing mill roll selected for the centrifugal casting ductile iron needle roller or high-speed steel roll. High speed steel roll working layer of high hardness, can reach HS80 ~ 85, has good wear resistance and thermal crack resistance, hot roll surface crack does not appear, generally do not spalling.
