Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel
Process design is the ensemble of operations leading from the design geometry to , production surface and by the restraining system , all other factors influencing sheet metal forming, we should recall that a sheet metal forming operation can always be.
The Hot Rolling Process - California Steel Industries
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
