The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0 %. The EAF method, however, feeds recycled steel scrap through high power electric arcs (with temperatures of up to 1,650 degrees Celsius) to melt the metal and convert it into high quality steel.
احصل على السعرSteel manufacturing methods have evolved dramatically since the processes of the industrial revolution began in the mid 19th century. However modern methods are still based on the Bessemer process which was practised over 150 years ago. This was a way to introduce oxygen into molten iron in order to reduce the amount of carbon contained [ ]
