Design of a New Type Casting Rolling Mill Screw down System

Abstract:

Considering the advantages and disadvantages of the mill screw down system now, a new type screw down system of caster is designed in this paper. Electro-hydraulic double-precision device is adopted in the synchronized screw down system.Bilateral synchronous motor is adopted first for coarse adjustment, and then use hydraulic servo cylinder to realize synchronization precision adjustment. It can adjust roll gap with double-precision, which can both achieve the purpose of rapid screw down and meet the accuracy requirements of the roll gap adjustment. Rotate both sides of screw down nuts using one hydraulic cylinder to achieve simultaneous fine-tuning of the roll gap. While coarse and fine adjustment, the actions are coordinate and non-interference. The screw down nut designed is compound nut, which can effectively compensate for the loosening and improve the accuracy of the roll gap adjustment. By analyzing and comparing, the new type screw down system of caster has some advantages such as double-precision adjustment, well synchronization, easy to operate and low cost, which have practical significance to improve the performance of the twin-roll casting machine.
