The invention discloses a preparation method of a high-speed steel roll with compound modification treatment, belonging to the technical field of steel rolling. High-speed steel roll materials are smelted in an intermediate frequency induction furnace, and the chemical composition and mass fraction of molten steel in the furnace are controlled at 2.32‑2.49%C, 4.17‑4.33%W, 4.80‑4.98%Mo, 9.63‑9.85%Cr, 0.48 ‑0.66% Mn, 0.57‑0.81% Si, <0.035% S, <0.040% P, balance Fe; then the molten steel was heated to 1615‑1626 ℃, and aluminum was added after holding for 4‑5 minutes, followed by wire feeding After the high-speed steel is solidified, the core is filled with ductile iron under static conditions, and after quenching and tempering treatment, high-speed steel with excellent performance and good use effect can be obtained. roll. |
