Embodiment 1
[0022] A high-toughness, corrosion-resistant and wear-resistant ball, the mass percentage of each element composition is: C: 2.5%, Si: 1.2%, Mn: 1.7%, Ni: 3.1%, Cr: 6.5%, Mo: 0.5%, V : 0.5%, Cu: 0.25%, Y: 0.1%, P: 0.03%, S: 0.01%, and the balance is Fe and unavoidable impurities.
[0023] The production process of the above-mentioned high-toughness, corrosion-resistant and wear-resistant balls includes the following steps:
[0024] (1) Raw material smelting: Put all the raw materials into an intermediate frequency induction furnace for smelting. During the smelting process, the temperature of molten steel is kept at 1600°C to obtain molten steel with qualified chemical composition, and then carry out static slag removal treatment;
[0025] (2) Spheroidization treatment and inoculation treatment: the rare earth magnesium alloy spheroidizing agent with 1.5% of the total weight of molten steel is added in the spheroidizing bag, and the molten steel is spheroidized using the cover...
