History of Hot Strip Mills1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 Generation III Coil Box Hot Strip Mills. In the 1970s, Stelco of Canada developed the hot coil box designed for installation in hot strip mills ahead of the finish mill for coiling the transfer bar from the roughing mill and uncoiling it into the finishing mill.
The cluster mill stand has two work rolls and four or more backup rolls. The number of backup or supportingrolls depends upon the amount of support needed for the work (small diameter) rolls. Cluster mill is normally used in coldrolling operation. The cluster mill stand can have six rolls, 12 rolls, or 20 rolls.
SMS group offers singlestand cold rolling mills for a broad spectrum of aluminum alloys and thin strip and multistand tandem cold mills as the solution for a large production capacity. We completed our portfolio of cold rolling mills by the EDT rolling mill, especially designed for rolling and tempering of automotive grades.
In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC 70oC with strip recoil temperatures and interstand strip temperature rarely exceeding 160 oC depending on product.
The stateoftheart of both technology and operational practice of a hot rolling mill are discussed. The focus is first on the control of entry temperature in the finish mill. Transfer bar ...
The dedusting efficiency on the rough rolling mills reaches up to % and % on the finish rolling mills, depending on the real test data of the dust concentration. In the simulation scenarios, comparing with the dedusting scenario without the atomized spray, the dust concentration at almost all seconds declines significantly after using ...

In 1923, MeerMaschinenfabrik delivered its first tube rolling mill to the Poensgen works of Phoenix AG für Bergbau und Hüttenbetrieb in Düsseldorf. From 1926 until the end of the 1990s, "Meer" was part of the Mannesmann group and, following its integration into SMS, continued to drive seamless tube production technology forward through ...
The results of simulation of the parameters of rolling and electric drives are compared to experimental data obtained by oscillography on the Severstal 1700 fivestand coldrolling mill.

Abstract. A numerical or graphical method is given for computing, in strip or plate rolling, the distribution of roll pressure over the arc of contact and the quantities derived from this ( the vertical roll force, the torque, and the power consumption). The method avoids all mathematical approximations previously used in the theoretical ...
In Section 3, the dynamic model of the rolling mill undergoes approximate linearisation through Taylor series expansion and through the computation of the associated Jacobian matrices. In Section 4, the Hinfinity control problem is formulated for the linearised model of the rolling mills and a stabilising feedback control law is proposed for it.

This obviates the transport of material from one side of rolls to the other after one pass is over. 3. Four High Rolling Mills. Four High Rolling Mill. As shown in the above figure, this mill consists of four horizontal rolls, two of smaller diameter and two much larger ones. The larger rolls are called backup rolls.
In one of his drawings, Da Vinci designed a rolling mill featuring a pair of rollers. With that said, modernday rolling mills didn't emerge until the 19th century. In 1820, Bedlington Ironworks produced one of the world's first railbased rolling mills. Railbased rolling mills are those that are designed to create long and narrow beams or ...
