The main skills of using quenching furnace include the following aspects:
Process parameter setting: According to the material, shape, size and heat treatment requirements of the workpiece to be processed, accurately set the heating temperature, holding time, quenching medium and other process parameters. Ensure that these parameters meet the specific heat treatment requirements.
Equipment operation steps:
Preparation: Check the equipment condition to ensure the sealing of the furnace body, the integrity of the heating element, the normal operation of the vacuum system, the unobstructed cooling system, etc. Clean the workpiece to be processed, remove impurities such as oil and rust on the surface, and ensure the cleanliness of the workpiece surface.
Loading: Place the workpiece on the special equipment fixture or tray in the furnace, pay attention to the placement and spacing, and ensure uniform heating and cooling of the quality.
Heating: Start the heating element, heat the workpiece according to the set heating curve, accurately control the temperature rise rate and the final temperature, and ensure that the workpiece is heated evenly.
Hot-keeping: After the workpiece reaches the set temperature, it enters the heat-keeping stage, and strictly controls the heat-keeping time to completely transform the internal structure of the workpiece.
Cooling: After the insulation is completed, rapid cooling is carried out. Control the flow and temperature of the quenching medium to ensure the cooling effect.
Monitoring and maintenance:
Real-time monitoring: During the heating and cooling process, continuously monitor parameters such as temperature and vacuum degree, and make necessary adjustments according to actual conditions.
Regular inspection: Regularly check the condition of the equipment, especially the gas supply system and cooling system, to ensure the normal operation of the equipment.
Maintenance: The modular design of the induction coil is easy to maintain, and the closed-loop cooling system reduces the risk of scale blockage and extends the operating life of the equipment.
Safety precautions:
Environmental inspection: Ensure that there are no flammable and explosive items around the furnace body, and check whether the internal and external circulating water supply, gas supply, electrical system, etc. are normal.
Operation specification: The operator must be familiar with the various operation buttons and daily operation skills of the equipment. Do not repair or modify the operating program parameters at will unless there are special circumstances.
