Planetary Rolling Mill In the planetary mill type of rolling machine, a large backup roller is surrounded by a number of planetary working rollers as shown in the figure. Each planetary roll gives a continuous reduction. It is employed to reduce large thicknesses in a single pass of a steel strip.
· Reasonable design of roll pass schedule is the prerequisite for a successful shape rolling process. In this paper three dimensional elastoplastic finite element simulation with thermal mechanically coupled analysis is applied to study the roll pass design of the hot continuous rolling of Ф100mm alloy steel round bar from 200mm×200mm square cast bloom.
Continuous casting (CC) is a method of producing an infinite solid strand from liquid steel by continuously solidifying it as it moves through a Continuous casting machine. It is a modern steel plant which links steelmaking and hot rolling including horizontal continuous casting machine and vertical continuous casting machine.

For the imperfection of the roll gaps, variation occurs on the rolling sheets. If the thickness varies and along with that volume and width are constant then the center is shortened than the edges. But the body is continuous. Then the edges portions are in the compression and the center portion is the tension. The result of the edge is wavy. Zipper Cracks in Centre of Strip: Zipper Crack is a ...
