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. Tempra: la barra d’acciaio temprata entra nella piattaforma di carico attraverso il dispositivo di trazione posteriore meccanico e viene alimentata passo dopo passo nella tavola a rulli paralleli, quindi inviata alla macchina di trazione meccanica prima del sensore di potenza a frequenza intermedia, e la barra d’acciaio si muove costantemente attraverso la macchina di trazione, l’asta d’acciaio viene inviata al sensore per la tempera, quindi entra nell’incubatore di tempera dopo la misurazione della temperatura, la conservazione del calore viene ritardata, dopo la tempera, viene riscaldata e raddrizzata, quindi inviata alla rulliera parallela;

4. Raffreddamento e raddrizzatura: la barra d’acciaio entra nel letto di raffreddamento per laminare e raffreddare naturalmente e, dopo il raffreddamento, viene inviata alla raddrizzatrice per la raddrizzatura e subisce un trattamento di smagnetizzazione.

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.
