Abstract

The invention relates to a intelligent type HF induction heating apparatus comprising set key, foot pedal switch, master control board. The master control board comprises frequency, locking phase control circuit, switching control circuit, power adjusting control circuit, and fault signal change-over circuit; the master control board is controlled by single chip machine which is provided with EEROM memorizer and heat insulation change-over circuit. Parameter is set and function is converted for the single chip machine by setting time length of pressing key and releasing key. The invention accomplishes full-automatic control, free choice for heat insulation and cooling during whole automatic control process, instant stop function and manual conversion.

Description

technical field [0001] The invention relates to an induction heating device, in particular to a high-frequency or ultra-high-frequency induction heating device capable of self-control. Background technique [0002] "Induction heating equipment" has many models and specifications. According to the frequency, there are intermediate frequency, high frequency, and ultra-high frequency; according to the output power, the small ones are 2KVA-20KVA, and the medium-sized ones are 25KVA-160KVA. , The large ones are 200KVA-2000KVA. The higher the power, the lower the frequency. Medium-sized and large-sized ones are generally used for melting, casting, forging, heat treatment of large workpieces, etc. Small ones are generally used for brazing, heat treatment of small workpieces, etc. Because induction heating has the advantages of energy saving, fast heating speed, and convenient use, it is an emerging industry that has been developing continuously in the past ten years.
