Embodiment 1
[0038] 1. Carry out smelting and casting according to the following composition to obtain a steel ingot: 1.0% by weight of C, 0.8% by weight of Si, 1.0% by weight of Mn, 1.2% by weight of Mo, 7.0% by weight of Cr, 2.3% by weight of W, 0.6% by weight % of V, 0.8% by weight of Al, of which P≤0.03% by weight, S≤0.03% by weight, and the rest is Fe;
[0039] 2. Anneal the obtained smelted product (steel ingot) before hot rolling, wherein the annealing furnace temperature is 910 degrees Celsius, the annealing speed is 30 degrees Celsius per minute, and the hardness is 255HB;
[0040] 3. According to the precision required by the width and height of the slide, the annealed steel ingot is forged and then hot-rolled into a strip plate;
[0041] 4. Cut into sliding pieces according to the size requirements, and mill grooves;
[0042] 5. Quenching and tempering the cut slides in turn;
[0043] Quenching treatment: furnace temperature 1100 degrees Celsius, holding time 8 minutes; temper...
