Steel qualification (in the 18th century) was a laborious and time-consuming process. (1) Manufacturing of steel modify during the 19th century with Henry Bessemers invention of using a blast furnace rule for making steel.         During the 20th century, a rudimentary oxygen-furnace process and the electrical waiver furnace produced steel. The electric arc order acting is the least costly method of making steel. This uses scrap metal as its base.

Steel scrap from many sources such as old bridges, refrigerators and automobiles and former(a) sources are placed in an electric! arc furnace, where the utmost(prenominal) heat produced by carbon electrodes melts the scrap, converting it into molten steel. Establishments that use this method of producing steel are called electric arc furnace (EAF) mills or minimills.         The small initial capital investment required to handle up and operate an EAF mill has helped drive the growth of the production...
