Cold Cracking Analysis of Low Carbon High Sulfur Free-cutting Steel
Abstract：By means of metallographic microscope and scanning electron microscope analysis, found that cracking of low-carbon high sulfur free cutting steel is caused by the large particle inclusions near the surface of steel.The large size inclusions contain Zr, Na, Mg and other elements, which is caused by severe erosion of outlet and refractory in smelting process and the entrapment of mold flux.
