[0037] The present invention also provides a method for preparing the high-strength wear-resistant alloy steel material according to the above technical scheme, which includes the following steps:
[0038] (1) Melting steel source, chromium source, deoxidizer, silicon source, molybdenum source, nickel source, manganese source and rare earth cerium to obtain molten steel;
[0039] (2) Casting the molten steel obtained in the step (1) to obtain alloy steel castings;
[0040] (3) The alloy steel castings obtained in the step (2) are sequentially annealed, quenched and tempered to obtain a corrosion-resistant alloy steel material.
[0041] The invention melts the steel source, chromium source, deoxidizer, silicon source, molybdenum source, nickel source, manganese source and rare earth cerium to obtain molten steel. In the present invention, the chromium source is preferably ferrochrome, the steel source is preferably scrap steel, the silicon source is preferably ferrosilicon, the molybde...
Example Embodiment
[0057] Example 1
[0058] A high-strength wear-resistant alloy steel material, including the following components by weight percentage: C: 0.26%, Cr: 7.11%, Si: 0.83%, Mn: 0.67%, Mo: 0.42%, Ni: 0.73%, Ce: 0.2%, P≤0.04%, S≤0.04%, the balance is Fe.
[0059] The preparation method steps are as follows:
[0060] ①Use scrap steel, ferrochrome, aluminum deoxidizer, ferrosilicon, ferromolybdenum, nickel plate and ferromanganese as raw materials to obtain molten steel by smelting and slagging at 1600℃ in an intermediate frequency induction furnace for three times. The quality of aluminum deoxidizer is the quality of molten steel. When the melting temperature of molten steel reaches 1650℃, pour it into a ladle with a baking temperature of 800℃. Add the required mass percentage of rare earth cerium to the bottom of the ladle, continue smelting until the mixing is uniform, and then pour the molten steel into the casting In the mold, get alloy steel castings;
[0061] ②The obtained alloy steel...
