At the end of rolling, the retained strain exceeds the peak strain needed for recrystallization and recrystallization can occur on the ...

Automation and Control in Iron and Steel Industries

Processes in iron and steel industries are either metallurgical or rolling and refining processes. In metallurgical processes (sintering, pig iron production, steel production, continuous casting, electric arc furnaces, secondary metallurgy) the liquid phase of the metal is predominant while in forging, rolling and refining processes the metal is in the solid phase. UNESCO – EOLSS SAMPLE ...

An integrated model for hot rolling of steel strips ...

For hot rolling of steel strips, a computer simulation model was developed that completely integrates different phenomena such as the mechanics and the heat transport in the strip and the roll, and the metallurgical behavior of the strip.

A COST MODEL FOR THE EFFECT OF SETUP TIME REDUCTION IN ...

Avesta, located in mid-Sweden, where stainless steel strip is produced in an integrated mill with meltshop, continuous casting and hot rolling. The Avesta plant has a traditional functional organization, with each production step managed as a separate unit. This has resulted in a decoupled operation of meltshop and continuous casting (CC) on one hand, and hot rolling mill () on the other ...

Rolling (metalworking) - Wikipedia

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.

Steelmaking-Hot Rolling Scheduling Model and Method …

Abstract: Based on the analysis of the rolling process in iron and steel enterprises, an optimal load distribution model is established for rolling mills. The objective function is to minimize the total energy consumption. The equipment and process constraints are considered. The particle swarm optimization (PSO) is employed to get the optimal rolling reductions. The simulation of a six-frame ...

Steel mill - Wikipedia

A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also describe plants where steel semi-finished casting products (blooms, ingots, slabs, billets) are made, from molten pig iron or from scrap. History. Since the invention of the Bessemer ...
