Tool steel hot-rolled steel strip and preparing method thereof

The invention relates to a tool steel hot-rolled steel strip and a preparing method thereof. The tool steel hot-rolled steel strip comprises following components including, by mass percent, 0.52%-0.59% of C, 0.60-0.90% of Mn, 0.15%-0.35% of Si, 0-0.015% of S, 0-0.030% of P, 0.020%-0.040% of Ti, 0.0012%-0.0035% of B, 0.010%-0.050% of Als, 0-0.20% of Cu, 0-0.5% of impurities and the balance Fe. Thetool steel hot-rolled steel strip has high hardenability, high abrasion resistance and good punching resistance, the production technology is high in operability and good in controllability, industrial production is easy, and the production cost is low. 本发明涉及一种工具钢热轧钢带及其制备方法，按质量百分比，由以下组分组成：C：0.52％～0.59％；Mn：0.60％～0.90％；Si：0.15％～0.35％；S：0～0.015％；P：0～0.030％；Ti：0.020％～0.040％；B：0.0012％～0.0035％；Als：0.010％～0.050％；Cu：0～0.20％；杂质：0～0.5％；余量为Fe。本发明的工具钢热轧钢带具有高的淬硬性、高的耐磨性，以及良好的耐冲压性，生产工艺操作性强、可控性好，易于工业化生产，生产成本较低。
