The heating part of the steel roll forming machine includes a triangular cutting machine, a dyeing machine, a loading machine, a reversing device at the bottom of the heating furnace, a pipe drawing machine, a cooling table, etc.
The cold processing part includes straightening machine, cutting machine, hydraulic press, hydraulic test bed, wire cutting machine, loading machine and pipe drawing machine, which are the main equipment in welded pipe machinery and equipment. The loading machine is located at the entrance of the welding furnace, and can move back and forth along the track in front of the furnace at a speed of 50 m/min, sending the tube blanks rhythmically to the bottom of the furnace for heating.
Before the tube blank is sent into the heating furnace, one end must be cut into a trapezoid, so that it can easily enter the bowl. The pipe drawing machine is located at the exit end of the heating furnace, and can also move back and forth along the track at the end of the furnace at a speed of 30 m/min, which is symmetrical with the position of the loading machine. Both the loading machine and the tube pulling machine are specially equipped with a console, and the back and forth movement is controlled by a special person. From the console, the inside of the furnace can be clearly seen.
The steel pipe that has just been welded by the pipe drawing machine is still at a temperature of about 1300 degrees Celsius. It is sent to the No. 1 tunnel at a speed of 2-10 m/min through the No. 1 cooling table, and the No. 1 Kun road is about 2 m/s. The speed is sent to the sizing machine, and the temperature is cooled to between 800-1000 degrees Celsius.
