Thickened petroleum steel pipe quenching and tempering production line

Brief description: It has the ability of quenching, spraying, tempering, descaling and automatic straightening. After the production line was put into operation, the thickened petroleum steel pipe wall thickness was 0.3-88.9mm, the thickened petroleum steel pipe diameter was Φ73 -127mm, and the length was 8-12. 5m, which achieved good results. The total power of the intermediate frequency power supply of the system is about 8000kW, and the frequency used is 300-1000Hz. The product is heated to 920°C by an induction heating furnace and then quenched. The quenching method adopts a large flow high-pressure water pump twice uniformly and at a certain angle, so that there is no water in the pipe, and then enters the tempering zone and tempers to 720°C. High-pressure descaling is carried out through a tunnel, and after descaling, it is gradually cooled and recycled and packaged in a cooling bed. The quenching and tempering time of the whole steel pipe (about 11.2m in length) takes about 30S
