Nov 01, 2014 · The actual service life of couplings is estimated from the mill production and rolling schedule. The service life of the couplings is divided into the sequences depending of roll wearing.petroleum coke crushing machines coal russian. The roll service life before machining due to wearing was estimated after 4000 rolling tons of steel (about 15 working days or about 17,390 rolled billets)Learn More
A coupled vibration model of hot rolling mill rolls under multiple nonlinear effects is established by considering the nonlinear spring force produced by the hydraulic cylinder, the nonlinear friction between the work rolls, the dynamic variation of rolling force, and the effect of external excitation as well as according to the structural constraints of a four-high hot rolling mill in theLearn More
There are many types of spindles used in industrial applications. Rolling mill spindles are used to transfer the power from a gearbox or pinion stand to a set of mill rolls when a direct connection is not feasible or practical. Spindles are chosen based on their particular application for torque and speed. Most smaller diameter spindles are made from 4140 grade high strength steel bar while many larger diameter spindles used in a rolling mill …Learn More

According to the “Hill rolling force formula”, taking particular account of the influence from horizontal vibration of rolled piece in roll gap, a dynamic rolling force model is analyzed. Considering the interaction between vibration of strip and roll, the dynamic vibration model of rolling mill is established. On this basis, the time delayed feedback is introduced to control the vibrationLearn More

A coupling and decoupling device is arranged between the neck of the roll and the spindle head of the drive spindleLearn More
The rolls are rotated in opposite direction by means of electrical drive system (motor, gearbox, spindle and couplings). Depending on the direction of rotation of the rolls, the input material enters the gap between the rolls from one end and comes out from the other end with a reduced cross-section, the roll gap area being kept less than theLearn More
