Steel pipe quenching and tempering heat treatment equipment

Equipment name: steel pipe quenching and tempering heat treatment equipment

Workpiece size: diameter greater than 20mm

Power: 100—8000Kw

The specific process of the steel pipe quenching and tempering heat treatment equipment is:

1. Straightening: The steel bar is manually placed on the loading platform and leveled, and then sent to the parallel roller table by the loading machine in a step-by-step manner. It is straightened by the seven-roll straightener before the heat treatment, and after the straightening, it passes through the parallel Roller table, mechanical traction machine before feeding into the sensor;

2. Induction hardening: Through the steady-speed operation of the tractor, the steel bar is sent to the induction heating semiconductor frequency conversion device of the induction heating quenching system, and the steel bar is preheated by the output sensor cabinet and infrared thermometer control— —Temperature measurement—heating—automatic control of temperature measurement. When the quenching temperature is reached, it enters cooling and mechanical quenching. After the mechanical traction device enters the roller table, it is sent to the storage and loading platform, and at the same time, the unqualified products are separated and completed. Quenching process;

3. Tempering: The quenched steel bar enters the loading platform through the mechanical rear traction device and is fed into the parallel roller table in a step-by-step manner, and then sent to the mechanical traction machine before the intermediate frequency power sensor, and the steel bar moves steadily through the traction machine , The steel rod is sent to the sensor for tempering, and then enters the tempering incubator after temperature measurement, the heat preservation is delayed, after tempering, it is heated and straightened, and then sent to the parallel roller table;

4. Cooling and straightening: the steel bar enters the cooling bed to roll and cool naturally, and after cooling, it is sent to the straightening machine for straightening and undergoes demagnetization treatment.

5. Unloading inspection and storage;

The steel pipe quenching and tempering heat treatment equipment has a good human-machine interface, which can control the temperature and speed of the steel pipe in operation; display the frequency, power, steel pipe heating temperature, speed and other parameters; monitor the temperature rise of the steel pipe, Set the power distribution of the power supply; record various status parameters of the steel pipe, such as temperature, speed, steel pipe diameter, wall thickness, batch number and other parameters after heating, and send it to the management level regularly.
