n metallographic observation, less oxidation and decarbonization were found on the surface of oil casing and induction quenched steel, while the low carbon layer M0.10mm was found on the surface after solution treatment. The oxidation amount of oil casing after solution treatment and the scale on the surface of friction material after conventional heating solution have low yield. ~ 0.15% 20%. Inductive oxide Wu is not only a remarkably dense oxide film. The mechanical properties of room temperature steels give the smelting and vacuum induction of EAF steels. Different treatment methods of heating solution are adopted, and the same side effects after mechanical properties treatment at room temperature are compared.


The data show that the mechanical properties of the dissolved inch are at the same level after two days aging treatment. However, the quantity of induction heating steel in electric arc furnace and the metallurgical quality of casing are much lower than that of vacuum induction furnace steel. This kind of induction heating solution treatment makes up for the gap between steel and shows the advantages of spoon induction heating solution.
