Rolling Mill An Overview Sciencedirect Topics

2.1 experimental set up. a hille100 rolling mill with rolls of 225 mm diameter and 254 mm length, driven by a variable speed dc motor of 75 horse power, was used. the maximum rolling force, torque and speed are 1500kn, 13knm and 70 rpm respectively. the sensor roll.

4 there are total 11 stands of rolling mill in the whole production line, intermediate rolling mill is one ac motor drives six. finishing rolling mill is one dc drives two 6 the highest rolling speed of final products stands to roll φ10mm. deformed bar is 8ms. equipment characteristic. 1. rolling mill stand adopts prestressed.

Csis hot strip mill includes six finishing mills, which reduce the thickness of the transfer bar down to the gauge required by the customer or the next process. the rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, between 1500 to 1650 f, specified to reach certain mechanical properties.

Dc motors speed synchronization for rolling mills the project aims at designing a system which is capable of synchronizing the speed of the slave motor (motor2) with the master motor (motor1). this system finds very useful in paper mills, steel industries etc..,. the master motor speed can be set.

Except for bloom rolling and slab rolling stands, the power from motor goes to gear box for speed reduction and then to pinion box for distributing the power between two rolls (fig.7.14). in slab rolling and bloom rolling mills, no gear box is used, motors are connected directly to rolls through universal couplings. where.

Torsional Vibration Suppression Control In The Main Drive

Abstract: in the rolling mill main drive system, a shaft torsional vibration is often generated when a motor and a roll are connected with a flexible shaft. the state feedback control can effective suppress the torsional vibration of the main drive system of rolling mill. because of the difficulty of measuring the load speed and the shaft torque, moreover the sensitive of luenberger observer.

Dynamic model. the rolling mill drive system mainly consists of the motor, reducer, main shaft, speed divider, arc gear shaft, work roll and bearings at corresponding parts .the torsional vibration is often closely related to the dynamic energy transformation process of the rolling interface, which causes the relative speed between the strip and work roll change on the rolling interface.
