Selection of induction heating equipment for heat treatment of hardware tools

One, the shape and size of the heated workpiece

Induction heating equipment with relatively high power and low frequency should be used for large workpieces, bars and solid materials; induction heating equipment with relatively low power and high frequency should be used for small workpieces, pipes, plates, gears, etc.

Second, the depth and area to be heated

The heating depth is deep, the area is large, and the overall heating should be high-power, low-frequency induction heating equipment; the heating depth is shallow, the area is small, and local heating is used. Induction heating equipment with relatively low power and high frequency should be selected.

Three, the required heating rate

If the heating speed is fast, the induction heating equipment with relatively large power and relatively low frequency should be selected.

Four, the continuous working time of the equipment

The continuous working time is long. Relatively choose the induction heating equipment with a little higher power. On the contrary, choose the equipment with relatively lower power.

Fifth, the connection distance between the sensing component and the equipment

The connection is long, and even water-cooled cables are needed for connection. Induction heating equipment with relatively high power should be used.

Six, process requirements

Generally speaking, for quenching, welding and other processes, you can choose a lower power and a higher frequency; for tempering, annealing and other processes, choose a higher relative power and a lower frequency; red punching, hot forging, and smelting If a process with a good diathermy effect is required, the power should be larger and the frequency should be lower. Hardware tool seven, the material of the workpiece

In the metal materials, the higher melting point is relatively large, the lower melting point is relatively small; the lower the resistivity is the higher the power, and the higher the resistivity is the lower.
