Large Billet Heating Process – Medium-Frequency Induction Heating Equipment
Large billet heating process, medium-frequency induction heating equipment
1. Preparation for heating large billets:
Clean the surface of the bar stock to be heated, removing oil, rust, and other impurities.
Based on the specific dimensions and shape of the bar stock, select an appropriate induction coil and adjust its position to ensure uniform heating.
Parameter Settings:
Set the heating frequency, power, and duration. These parameters need to be determined based on the material (such as carbon steel, alloy steel, stainless steel, etc.) and dimensions of the bar stock.
Generally, the heat treatment temperature depends on the specific process requirements; for example, the quenching temperature may be in the range of... 800°C To 950°C Between, the annealing temperature may be in 600°C To 700°C Between.
2. Induction heating furnace's Heating process:
Place the bar stock into the induction coil and start the medium-frequency induction heating equipment.
A medium-frequency magnetic field is generated via an induction coil, inducing eddy currents within the bar stock and rapidly heating it.
Use a temperature sensor to monitor the temperature during the heating process and ensure that the desired heating temperature is reached.
During the heating process, heating parameters can be adjusted in real time via an automated control system to maintain temperature stability and uniformity.
3. Subsequent processing:
Once the bar stock reaches the predetermined heating temperature, it undergoes subsequent processing—such as quenching, forging, bending, and others—depending on the specific application requirements.
For heat treatment processes, such as quenching, the bar stock must be rapidly immersed in a cooling medium—typically water or a specialized quenching oil—to quickly cool the surface and form a hardened layer.
After quenching, tempering is usually required to relieve internal stresses and stabilize the microstructure.
