Sendzimir 20 High Mill
Sendzimir 20 High Mill The essential difference between Sendzimir cold rolling mill and four high rolling mill or other types of rolling mill is the different transmission direction of rolling force. The rolling force of the Sendzimir cold rolling mill is transferred from the work roll to the backup roll device through the intermediate roll, and finally to the solid overall stand. This design ensures the support of the work roll in the whole length direction. In this way, the roll system deformation is very small, and the very accurate thickness deviation can be obtained in the whole width direction of rolling. Sendzimir mill has the following main characteristics in structure and performance (1) The frame with integral casting (or forging) has high rigidity, and the rolling force acts radially on each section of the frame. (2) The work roll diameter is small, and the pass reduction rate is large, up to 60%. Some materials can be rolled into very thin strips without intermediate anne
