### Hot Rolling Mill Hydraulic Gap Control HGC thickness

cylinders are used to apply a counteracting force on the work roll chocks to reduce the roll bending thus controlling the cross profile partially. measured HGC pressure and can be used to calculate the mill stretch. The mill V – roll speed F - roll force a b – constants. Figure 4

### PDF Methodology for Calculation of Rolling Load and

Rolling load calculation: 3.1 Properties of Material to be used for Hot Rolling: Material – A36 Mild Steel UTS – 400 Mpa Yield Strength – 250 Mpa Elongation – 20% Carbon – 0.26 Density – 7800 kg/m^3 Poisons ratio – 0.26 Shear Modulus – 79.3 Gpa Table 1: Effect of Temp on UTS PASSES TEMPARATURE ̊C ULTIMATE TENSILE STRENGTH

### PROCESS OF ROLLING MILLS

Calculation of roll force is important because calculation of torque and power in a rolling mill is based on calculation of roll force. stretch reduce the cross section of the bar making shape

### Calculation Of Speed Of Roll In Stretch Reducing Mill

Patent US3592031 - Automatic control of rolling mills - Google Patents. v. setting roll gap and speed-controlling devices of the mill for the respective rolling stages in accordance with the values determined in the preceding step and with the mill stretch characteristics.

### Stretching reducing on a tube or pipe mill

A conventional forge welding mill already includes sizing stands to reduce the tube to its final size normally a 1 percent reduction. Adding a few roll stands and using the cold-stretch-reducing CSR process can expand this mill’s capability enabling reductions of more than 50 percent.

### Roller mill - Feed Mill Machinery Glossary FeedMachinery.com

Typical roll speeds would be 1300 feet per minute 395 m/min for a 9-inch 23 cm roll to 3140 feet per minute 957 m/min for a 12-inch 30.5 cm roll. Usually a single motor is used to power a two high roll pair with either belt or chain reduction supplying the differential.

### The basics of roll form tooling design

You can successfully roll-form a profile more than one way. In fact many roll form designers take different approaches to design and development. Also because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables many roll form designs are one-of-a-kind; therefore theory can go only so far.
