3.2 Control of S and N3.2.1 Control of w(S)There is no S source for smelting cast iron in medium frequency furnace, and the w(S) content of molten iron is low. Therefore, it has great advantages for producing ductile iron, but for gray cast iron, low S and high Mn will increase casting stress, greatly increase excerpt …
