Background

Enamel cooking pots have been widely used in households, and are popular among people because of the characteristics of beauty, cleanness, corrosion resistance, high temperature resistance and quick heat transfer. However, the enamel cooker is easy to stick the bottom of the cooker when being used improperly. In recent years, a large number of non-stick pan bodies are sold on the market, most of the non-stick pan bodies adopt aluminum alloy or steel plates as blanks, and a layer of non-stick coating is coated on the inner surface of a pan body, so that the problem that the pan bottom of a common pan is easy to stick is solved. However, the aluminum alloy non-stick pan has high cost, thick material, large using amount and high price, and consumers are reluctant to bear the aluminum alloy non-stick pan. Although the cost of using steel plate as blank can be reduced, the use of steel plate, especially the use of coal stove, is easy to produce oxidation and falling phenomenon to affect the service life.
