一种冰刀刀背用带材的制备方法，属于金属材料领域。本发明按质量分数C:0.2‑0.3％；Si:0 .2‑0 .4％；Mn:0 .5‑1 .2％；Cr:5 .5‑7 .5％；Mo:1.0‑2.5％；W:1.0‑2.5％；N：0‑0.03％，余量为Fe进行配料，然后采用真空或非真空感应熔炼炉进行熔炼得到铸锭，将铸锭进行电渣重熔后得到电渣锭，再通过锻造、热轧、酸洗、退火、冷轧、切割分条工序得到用于制作刀背的带材成品。该材料经过1080～1160℃固溶后淬火，再于500～600℃回火，具有优异的抗疲劳性能、刚度和强韧性，将其作为冰刀刀片的背材可大幅度提高冰刀刀片的可靠性和使用性能，同时该材料还可用作双金属锯条的背材。

The invention relates to a preparation method of a strip for the back of a skate blade, which belongs to the field of metal materials. The invention is based on the mass fraction C: 0.2 ‑ 0.3%; Si:0 .2‑0 .4％； Mn:0 .5‑1 .2％； Cr:5 .5‑7 .5％； Mo:1.0‑2.5％； W:1.0‑2.5％； N: 0 ‑ 0.03%, the allowance is Fe, and then the ingot is obtained by smelting in vacuum or non-vacuum induction melting furnace. The ingot is electroslag remelted to obtain the electroslag ingot, and then the finished strip for making the knife back is obtained by forging, hot rolling, pickling, annealing, cold rolling, and cutting. The material is quenched after solution at 1080~1160 ℃, and then tempered at 500~600 ℃. It has excellent fatigue resistance, rigidity, strength and toughness. Using it as the backing material of the blade can greatly improve the reliability and service performance of the blade. At the same time, the material can also be used as the backing material of the bimetal saw blade.
