Cooling of the material after hot rolling in conjunc-tion with the finish-rolling temperature plays a key role for achievement of the final structure and mechanical properties. In the case of rolling of steel characterised by phase transformation (e.g. austenite/ferrite) the dif-ference between the temperature of finish-rolling and
As a result, steel mills were historically located on major waterways and at one time defined the economies of states like Wisconsin, Michigan, Ohio and Pennsylvania. Then came mini mill technology. Mini mills use electric arc furnaces to re-melt, refine and alloy scrap steel in smaller, lower-cost operations that are independent of traditional supplies of iron ore and coke.
Steel Rolling Abstract: Rolling is an indirect compression process. Normally the only force or stress applied is the radial pressure from the rolls. This deforms the metal and pulls it through the roll gap. The process can be compared to compression or forging but differs in two respects in that compression takes place between a pair of platens ...
