Quenching of Steel: Purpose and Mechanism Industries

Oil cools hot steel less rapidly than water, and the larger the piece quenched, the slower is the cooling rate. One advantage of the slower cooling is reduced danger of warping. In the oil quenched part, the stress distribution is generally more uniform than in a water quenched steel. The quenching media can be classified into five groups: (a

Steel mill Wikipedia

History. Since the invention of the Bessemer process, steel mills have replaced ironworks, based on puddling or fining methods. New ways to produce steel appeared later: from scrap melted in an electric arc furnace and, more recently, from direct reduced iron processes.. In the late 19th and early 20th centuries the world's largest steel mill was the Barrow Hematite Steel Company steelworks
