Cold rolling mill

Cold rolling mill machine is a kind of equipment to process the sheet or strip of metal (usually steel or aluminum) to achieve the required thickness and properties by rolling several times at room temperature. Cold rolling process can improve the surface quality, mechanical properties and dimensional accuracy of sheet metal, is a very important part of the metallurgical industry. What is a cold rolling mill machine? Cold rolling mill is an important equipment for metal processing, which is used to roll metal sheets and strips to the required thickness at room temperature. According to the operation mode and application requirements, cold rolling mills are mainly divided into two types: reversible cold rolling mills and continuous cold rolling mills. They have their own characteristics in terms of working principle, structure and scope of application. Principle of operation of reversible cold rolling mill machine Reversible Cold Rolling Mill (Reversible Cold Rolling Mill) is a kind of cold rolling equipment that can realize the reciprocating passage of steel strip in the mill by changing the direction of rotation of rolls. 1. Single Stand Reciprocating Rolling • The steel strip is unwound through the inlet coiling device (Uncoiler) and passes through the mill stand into the outlet coiling device (Coiler). • The strip can pass through the same mill stand repeatedly during the rolling process, with the direction of the rolls being controlled by a motorized drive system that reverses the direction of the rolls. • Each pass is called a “pass” and each pass gradually reduces the thickness of the strip until the target thickness is reached.
