Steel pipe quenching uniform method
For steel pipes with relatively thin walls. The steel pipe is heated to about 1000 ℃ by the steel pipe heating equipment, and is sent to the waiting area by the feeding roller table. The loading device lifts the steel pipe and turns it over to the slowly rotating support wheel of the rotating device, which is installed on the spray frame. The compression device quickly compresses the steel pipe, and the rapid rotation of the rotating device drives the steel pipe to rotate quickly. The outer shower pipe located directly above the steel pipe sprays water evenly on the outer surface of the steel pipe. At the same time, the inner spray device installed at the end of the steel pipe sprays water on the inner wall of the steel pipe. In this way, the inner and outer surfaces of the steel pipe are uniformly quenched.
