Problems solved by technology

[0004] However, the method of cold riveting the stainless steel bottom sheet at the bottom of the pot body has disadvantages such as not being tightly bonded, easy to fall off, easily causing product deformation and concave, and requiring the pot to have a flat bottom surface with a certain diameter.
The method of spraying iron and stainless steel on the bottom of the pot body is easy to rust and corrode, and an additional protective coating needs to be provided on the outside
The method of making the pot body by combining iron and stainless steel has high cost and complicated process, and it is prone to delamination at high temperature
In addition, the existing magnetic cooker still has the problems of high electromagnetic noise and slow heat transfer speed when used on the induction cooker
