a high-capacity rolling mill for the reduction into blooms of steel ingots of large cross section with masses up to 12 tons and larger. In some cases a blooming mill is used for the rolling of slabs and also shaped pieces for heavy I beams channel iron and the like.

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77000 hp and finally coiling up the lengthened steel sheet for transport to the next process.

A drive for a roll stand having a reciprocal frame has a pair of substantially identical cranks rotating about respective crank axes offset from the frame respective connecting rods pivoted on and connected between the cranks and the frame and respective counterweight on the cranks opposite the respective arms. The cranks rods and counterweights flank a central plane.

PDF On Nov 2 2018 Yu B Chechulin and others published Optimal selection of the parameters of the kinematic chain of the main drive of the cold rolling mill

In the top-driven mills of the prior art the drive spindle rests on top of the roll. Thus the weight of the drive spindle joints and pod coupling must be supported by the mill roll and the bearings on which the roll rests. The mill rolls in all vertical rolling mills are subject to

In a 1220mm temper mill the cross bow was serious which seriously affected the units output and efficiency. In order to solve this problem the mechanism of cross bow is studied in rolling of single-roll transmission temper mill. First established the FEM of the single-roll drive temper mill rolling analyzed the distribution factors of vertical extension in thickness.

The analysis of rolling mill vibrations is usually limited to simple planar or low DOF vibrations. In reality however rolling mill vibrations take place in six DOF leading to spatial behaviors involving vertical horizontal axial reverse cross and swinging vibration modes resulting in complex relative motions between the rolls.
