Example Embodiment
[0017] Example one
[0018] The steel for high-strength wear-resistant ball mill steel balls proposed by the present invention includes the following components by weight percentage: C0.95%, Si 0.3%, Mn 0.95%, Cr 1.2%, W 0.19%, Ti 0.08%, P 0.01% , S 0.02%, the balance is Fe and a small amount of impurities.
[0019] The preparation method includes the following steps:
[0020] S1: Smelting, smelting, heating the temperature of the smelting furnace to 1700°C, and adding W, Fe, Cr, and Ti with corresponding specific gravities into the smelting furnace for smelting. After all of them are melted, molten steel is obtained;
[0021] S2: Refining, transfer the above molten steel to a refining furnace at a temperature of 1480°C, add C, Si, Mn, P and S with the corresponding specific gravity, and add hexachloroethane for preliminary refining, and then after the preliminary refining The molten steel undergoes a vacuum degassing process, controlling the pressure of the vacuum chamber at 50-80Pa...
