摘要（英）：

The invention discloses a low carbon chromium-molybdenum steel based WC50 steel bond hard alloy guide roller and a manufacturing method thereof. Low carbon chromium-molybdenum steel based WC50 steel bond hard alloy including the chemical components of, by mass percentage, of 0.25-0.3% of C, 0.5-0.6% of Cr, 0.25-0.3% of Mo, 0.6-0.7% of Mn, 0.4-0.6% of Si, 50% of WC and the balance Fe is adopted, and then the low carbon chromium-molybdenum steel based WC50 steel bond hard alloy is subjected to forging, annealing, machining, heat treatment, grinding and detection, so that the guide roller is finally obtained. The steel bond hard alloy guide roller prepared through the method has the excellent physical and mechanical properties of high hardness, abrasion resistance, resistance to high temperature oxidation, resistance to heat impact and the like, the service life of the guide roller is prolonged, the steel rolling production efficiency and product quality are improved, the production cost is low, quite high cost performance is achieved, and great economic and social benefits are achieved.
