[0022] Example 1
[0023] The anti-corrosion, high-hardness, wear-resistant alloy cast ball of the present invention is prepared according to the following process:
[0024] S1. Smelting: Add high-carbon ferrochrome, low-carbon ferrochrome, scrap, ferromolybdenum, ferrovanadium, ferro tungsten, ferro-niobium, and ferro-titanium into the high-frequency induction melting furnace, and pass argon into the induction furnace to induce induction The oxygen content in the furnace is less than 3%, and the flow rate of argon is 25L / min. After closing the furnace door, raise the temperature of the induction furnace to 2500°C. After the above-mentioned raw materials are all melted, open the furnace door and add ferroboron, ferromanganese, magnesium-nickel alloy, Silicon-calcium alloy, zirconium iron, metallic zinc, metallic copper, metallic rhenium, carbon powder with a particle size of 55-60μm and silicon powder with a particle size of 30-50μm, close the furnace door again and raise the tempe...
