Steel plate quenching and tempering production line
The steel plate quenching and tempering production line is suitable for the heat treatment of reinforced steel plates such as high-strength steel plates, armored bullet-proof plates (military 616, 6211, etc.), wear plates (NM400, etc.).
The steel plate quenching and tempering production line can process the thinnest 2mm steel plate and the longest steel plate of 12.5 meters. The flatness after quenching is ≤3mm/m2, and no leveling is required after quenching; the deviation of the hardness value (dHB) on the same steel plate does not exceed 0.3mm.
Process method and characteristics of plate quenching and tempering equipment:
The steel plate is quenched and tempered through straightening-induction heating-induction hardening-induction tempering-rolling cooling and completed on a continuous production line.
Configuration selection of steel plate quenching and tempering production line:
1. Induction heating furnace for quenching and tempering.
2. Input and output racks
3. Automatic unloading system
4. Medium frequency induction heating power supply
5. Closed cooling water circulation system.

Advantages of steel plate quenching and tempering production line:
1. The workpiece can be heated uniformly; the temperature can be precisely controlled.
2. The steel plate quenching and tempering production line has fast heating speed, no oxidation and decarburization, and high heating efficiency.
3. The plate electric heating equipment has low energy consumption and high thermal efficiency.
4. The steel plate quenching and tempering production line has simple production operation, flexible operation and high degree of automation.
5. The medium and thick plates after the steel plate quenching and tempering production line have no deformation, no cracks, and high hardness.
The advantages of uniformity of heating of the steel plate quenching and tempering production line The
plate heat treatment production line adopts a fixed quenching method. Through a reasonable waterway and structure design, while ensuring uniform spray quenching, the thin steel plate can be obtained by maintaining the pressure of the indenter. The flatness of the steel plate quenching and heat treatment production line to avoid the uniform heating of the soft spot steel plate quenching and tempering production line. The steel plate quenching and tempering production line uses computer simulation technology to simulate the plate shape change during the quenching and heat treatment of the steel plate. The water circuit and nozzle arrangement are reasonably designed to ensure the spray Uniformity of quenching. The steel plate quenching heat treatment production line is calculated based on the production capacity. The steel plate in the furnace can be heated in the furnace to swing, thereby reducing the length of the heating furnace, reducing the investment and energy consumption, and achieving the best economical of the steel plate.
Advantages of steel plate quenching and tempering production line:
1. PLC control, the whole line is intelligent and automated
2. The automatic control system has the functions of material tracking, temperature control, protective atmosphere metering and control, heat balance data analysis, fault alarm, steel plate quenching heat treatment production report and other functions.
