Embodiment 1
[0021] The preparation of embodiment 1 high plasticity low alloy high-speed steel W4Mo2Cr4V
[0022] (1) Strict selection of raw materials for W4Mo2Cr4V high-speed steelmaking. The S content in the raw materials is 0.007%, the P content is 0.022%, the Ni content is 0.21%, and the Cu content is 0.18%.
[0023] (2) Smelt W4Mo2Cr4V high-speed steel in a vacuum induction melting furnace. After the composition meets the requirements, cast the self-consumable electrode rod and cool it slowly to room temperature;
[0024] (3) Use a vacuum consumable remelting furnace to remelt the consumable electrode rod, thereby reducing the gas and impurity content in the steel; during the vacuum consumable process, by binding calcium iron wire on the consumable electrode rod, Carry out calcium microalloying treatment, calcium addition is 0.5% of total mass; Make high-speed steel remelting ingot, the oxygen content in the high-speed steel remelting ingot is 12ppm, nitrogen content is 50ppm, and hy...
