Advantages of induction heating:
1. High efficiency
The efficiency of induction heating is 30% to 50% higher than that of flame furnace, 20% to 30% higher than the resistance furnace, and it has obvious energy saving effect.
2. Heating temperature and short time.
It shows that induction heating is more efficient than resistance furnace and flame furnace, and the unit time is high.
The heating rate is fast, the surface oxidation skin loss rate of the heating metal working surface is low, and the materials and expenses are saved, which is especially important for the heating of precious metals.
3. Easy to realize automatic control.
Induction heating can be according to the current state of the heated workpieces, real-time, accurate automatic control, such as through the analog or digital circuit processing, adjust the power frequency, automatically adjust the heating temperature or depth of components, meet the technological requirements.
Improve and protect the environment.
Induction heating does not produce waste gases such as carbon monoxide, carbon dioxide, sulfur oxide and soot, external radiation heat is small, low noise, work environment to purify, to protect air environment, operators to improve working conditions, health level to be able to guarantee.
5. Safe and reliable
Induction heating does not produce an open flame, which eliminates the possibility of fire, explosion and other dangerous events and greatly improves safety.
6. Easy to operate.
The main body of the modern induction heating device is the inverter induction heating power source with the power semiconductor power device as the core, without preheating, it can be started and closed at any time.
7. The installation site occupies a small area.
Now induction heating power supply structure is compact, its composition is almost a way of modularization, standardization of parts, quality, small volume is equal to the resistance furnace and flame furnace, equipment installation occupied land area and the space is little, the utilization rate of per unit area is high, save space and infrastructure costs.
8. Local heating of the workpiece can be carried out.
In v, induction heating process parameters output controllability is strong, good product quality qualified rate is high, energy saving, environmental protection, safe and reliable, is a kind of advanced technology, the application prospect of extensive heating mode.
