1 , bar production line quenching composition

The quenching system consists of photoelectric switch, adjustable sprinkler bracket, stainless steel jet water ring (two groups), water spray ring (set), gas-water mixing device (four sets), spray drying device, water pipe, valve, water tank, The filter system, each branch flow display table, infrared thermometer, spray water cooling device and the like. The water and gas switch is automatically completed by the solenoid valve, and the flow rate is adjusted by the electric proportional control valve.

2 , the working process of round steel quenching and tempering production line

The heating steel pipe continues to rotate and advance. When it enters the spraying device, there is a photoelectric detection switch for the on-beam detection. Once the incoming material is detected, the first group of sprays opens, and the second group of sprays opens, and then lags. The spray dryer is turned on.

In order to ensure the actual temperature after the steel pipe is sprayed dry, an infrared thermometer (American Leitai) is installed at the end of the spray drying device to provide reliable data for the tempering sensor and realize temperature closed-loop control.

At the end of the second section of the tempering sensor, an infrared thermometer (Reit) is also used to finally detect the actual temperature of the steel tube after induction heating by tempering.
