Abstract

The invention discloses a method for thermal spraying of a composite bottom layer of an aluminum pan of an electromagnetic oven, which is used in the manufacturing industry of food cookers and is as shown by a drawing appended to the abstract. A magnetic composite layer with a certain thickness is formed by using an automatic spraying method, designing the joint of a coating and the pan bottom into a concave mosaic structure and spraying a magnetic material (pure iron, iron alloy or 430 stainless steel) to the bottom of the aluminum pan so as to meet the operating requirements of the electromagnetic oven. According to the requirements of a product, one or more material (copper, stainless steel, aluminum, nickel, chromium or ceramic) coatings with different thicknesses or functions can be sprayed to realize aesthetic property, practicability and functionality of the electromagnetic oven pan to ensure that the pans for the electromagnetic oven become various middle-grade and high-grade series products.

Description

Technical field: [0001] The invention belongs to the food pot manufacturing industry in the field of food cookware. Using the method of automatic thermal spraying, the magnetic conductive material is sprayed on the bottom of the flat aluminum pan to form a composite layer with a certain thickness to meet the use of the induction cooker. According to the needs of the product, one or more layers of coatings with different thicknesses or different functional materials can be sprayed, such as copper, stainless steel, aluminum, nickel, chromium, ceramics, etc., to meet the aesthetics, practicability and functionality of the induction cooker. Make the induction cooker pot form a diversified series of products. Background technique: [0002] Food pots are closely related to people’s lives. They have a long history and many varieties are well known. They are usually divided into: iron pots, aluminum pots, stainless steel pots, copper pots, magnesium alloy pots, enamel pots, ceramic...
