The Hot Rolling Process

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 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

Düsseldorf-Rath Plug Mill

2019-10-10 · The plug rolling process used here has decades of success behind it and has been continuously refined over the years. To start with, steel ingots are preheated to about 1,300 °C and pierced in a cone-type pierce-rolling mill. In the upstream plug rolling mill, the resultant hollow shell is then rolled out over a plug to the desired wall thickness.

The Pickled coils are cold rolled on 4 Hi AGC cold rolling mill to obtain the required thickness and annealed in HSD fired bell-type annealing furnace for bright annealing. In case of medium and high carbon coils, the process of rolling and intermediate annealing can be repeated to a number of times depending upon the final thickness to be ...

Rolling (metalworking)

2019-10-11 · Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
