US5651440A Disengageable universal shaft for rolling mill

A disengageable universal shaft for rolling mill drives having a flange on the roll side that can be coupled centrally with the coupling sleeve attached to the roll shaft and a flange at the gear side that is connected with the drive via a spline shaft that enables the disengaging movement. The spline shaft is penetrated centrally by an extensible part of a piston These rolls are normally heat treated, the hardness range is 35 -55 deg Shore and they are normally used as back-up rolls in 4-high rolling mills. An alloy steel containing tungsten and with a hardness of 40 50 deg Shore is very resistant to fire cracking and is sometimes used for roughing rolls in hot strip mills.Rolling Mills Rolls IspatGuru

Nonlinear mechanical model of the shaft of a roll forming mill

The drive-side faces the drivetrain, and during production, at least one shaft of each forming pass is usually connected to the drivetrain. The operator-side stand can be removed easily to equip the shafts with rolls (which are not displayed in Fig. 1).Both stands are positioned on the mill bed with a feather key, and the mill bed mountings are The CNC rolling mill described in the previous section of this paper was used to perform rolling tests (in scale 1:5) of two types of car axles shown in Fig. 3.The rolling process was performed with the use of tapered rollers described by a diameter D R = 150 mm, a forming angle α = 20° and a sizing zone width b = 13 mm.

Manufacturing large shafts by a novel flexible skew rolling

Flexible skew rolling (FSR) with two rollers is a new technology for forming large shaft parts, which is especially suitable for manufacturing the shafts with small-batch and multi-variety.The surface hardness of hot rolling roll is hb190 ~ 270. The common failure forms and causes of rolls are as follows: Cracks. The roller cracks are mainly caused by the excessive local pressure and the rapid cooling and heating of the roller. On the rolling mill, if the emulsion nozzle is blocked, the local cooling condition of the roller isCommon Problems of Roller Hot Rolling Mill
