Example Embodiment
[0028] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0029] The forging process of 45A large double flange motor spindle includes the following steps:
[0030] a. According to the quality control requirements of raw materials, 45A steel ingots smelted by electric arc furnace + external refining + vacuum degassing are selected as raw materials, conforming to Q / HWG-QW07009-2000, and the content of harmful elements and gas in chemical composition is controlled to S≤0.020 , P≤0.015, H≤2ppm, O≤30ppm, N≤65ppm, Cu≤0.20, to ensure steel purity and grain refinement;
[0031] b, such as figure 1 As shown, the steel ingot is charged into a heating furnace with a temperature lower than 450°C for preheating and holding for 5 hours, then heating at 60°C per hour to 650°C for 4 hours, and then heating at 60°C per hour to 850°C for 5 hours. Finally, the temperature is increased at 80°C per hour to 1250°C for 2 hours, and the forgi...
