HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a key element of steel production.
[1-3], as well as work rolls crossing and shifting (RCS) [4] mills have been introduced and developed to improve the strip shape and profile. The PC mill was first used commercially at Nippon Steel's Kimitsu Works in 1991 [1], and it has been commonly used in hot rolling mills for plating and stripping as a finishing mill.

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.
P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement – 98 – Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness, the properties of the strip, roll gap, contact time and cooling parameters.
A Steel strip emerges from the hot section of a steel mill at a speed of 20 m/s and a temperature of 1200 K. Its length and thickness are L = 100 m and delta = 0.003 m, respectively, and its density and specific heat are 7900 kg/m^3 and 640 J/kg.K, respectively.
COUPLED PICKLING LINE & TANDEM COLD MILL High-capacity production of high-quality products For a wide range of products, the required strip thickness, flatness and surface quality can be achieved more economically by linking the pickling and cold-rolling processes.
Mar 16, 2016· To make gauges lighter than the hot strip mill can produce economically. To produce sheet and strip of more uniform thickness. Cold rolled base – Coils that are cold worked or reduced to gauge on the tandem mill. Cold rolling – Term applied to the operation of passing unheated metal through rolls for the purpose of reducing its gauge.

Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
