Method for heating stainless steel based on intelligent phase-breaking voltage reduction

The invention discloses a method for heating stainless steel based on intelligent phase-breaking voltage reduction, which belongs to the field of electromagnetic induction heating. The key points of the technical scheme of the invention are as follows: compiling and storing a stainless steel knife handle heating program; creating a 'stainless steel knife handle shrinkage fitting' option on an operation control interface; starting a heating button of a shrinkage fitting machine after selecting a 'stainless steel knife handle'; identifying the size of the stainless steel knife handle, and automatically disconnecting one phase of the three-phase current at the current input end in the circuit of a power coil; and according to the identified size of the stainless steel knife handle, introducing AC power of a specific frequency and time into the power coil to start heating the stainless steel knife handle. When the material of the knife handle is alloy steel, the input current is three-phase AC dynamic power. When
