The following aspects should be considered:
1) Shape and size of heated workpiece: induction heating equipment with high relative power and low frequency shall be selected for large workpiece, bar material and solid material;
2) For small workpieces, pipes, plates, gears, etc., induction heating equipment with low relative power and high frequency shall be selected.
3) Depth and area to be heated: the heating depth is deep, the area is large, and the induction heating equipment with high power and low frequency shall be selected for overall heating; With shallow heating depth, small area and local heating, induction heating equipment with low relative power and high frequency shall be selected. The required heating speed requires fast heating speed. Induction heating equipment with relatively large power and relatively high frequency shall be selected.
4) Continuous working time of the equipment: the continuous working time is long, and the induction heating equipment with slightly higher power is selected.
5) Connecting distance between inductive components and equipment: the connecting line is long and even needs to be connected with water-cooling cable. Induction heating equipment with large power shall be selected.
6) Process requirements: Generally speaking, quenching, welding and other processes can be selected with lower power and higher frequency; For annealing, tempering and other processes, select higher relative power and lower frequency; If processes with good diathermy effect are required for red stamping, hot calcination and smelting, the power should be greater and the frequency should be lower.
7) Material of workpiece: in metal materials, the relative selection power of high melting point is larger, and the relative selection power of low melting point is smaller; The power selected for low resistivity is larger, and the power selected for high resistivity is smaller. wait.
