Embodiment 1
[0014] Embodiment 1: A kind of high-strength corrosion-resistant steel gas cylinder hot spin forming method comprises the following steps,
[0015] (a) First heat the empty furnace to 1100°C, then place the closing section of the seamless steel pipe in the heating furnace to heat, heat the closing section of the seamless steel pipe at a heating temperature of 1100°C, and keep it at 1100°C for 10 minutes, so that The internal and external temperature of the seamless steel pipe is uniform, and the relationship between the heating length L and the outer diameter φ of the steel pipe is L=φ+(100-150mm);
[0016] (b) For discharging, fix one end of the heated seamless steel pipe on the spindle of the spinning machine, and the claws of the spindle of the spinning machine clamp the seamless steel pipe, and the time from discharging to clamping shall not exceed 45 seconds, and the time shall be 25- The seamless steel pipe is rotated at a speed of 29 rad / s, and the working surface of th...
Embodiment 2
[0018] Example 2: (a) First heat the empty furnace to 1160°C, then place the closing section of the seamless steel pipe in the heating furnace for heating, heat the closing section of the seamless steel pipe at a heating temperature of 1160°C, and keep it warm at 1160°C 10 minutes to make the temperature inside and outside of the seamless steel pipe uniform, the heating length is 600mm,
[0019] (b) For discharging, fix one end of the heated seamless steel pipe on the spindle of the spinning machine, and the claws of the spindle of the spinning machine clamp the seamless steel pipe, and the time from discharging to clamping shall not exceed 45 seconds, and the time shall be 25- The seamless steel pipe is rotated at a speed of 29 rad / s, and the working surface of the plate mold of the spinning machine is brought close to the other end of the seamless steel pipe, that is, the closing section. The distance between the axis of the rotating shaft of the plate mold and the axis of th...
