Multi-layer composite cookware and manufacturing method thereof

Abstract

The invention provides a multi-layer composite cookware. The multi-layer composite cookware sequentially comprises a first stainless steel layer, an energy storage layer and a second stainless steel layer from outside to inside. A plurality of annular reinforcing ribs are arranged on the faces, making contact with the energy storage layer, of the first stainless steel layer and the second stainless steel layer, and annular grooves used in cooperation with the reinforcing ribs are formed in the two faces of the energy storage layer. A plurality of first raised lines which are uniformly distributed are arranged on two sides of the reinforcing ribs and are arranged on one side, close to the energy storage layer, of the reinforcing ribs; a plurality of uniformly distributed second raised linesare arranged on the side walls of the two sides of the annular grooves, and are arranged on one side, far away from the energy storage layer, of the annular grooves; the first stainless steel layer,the energy storage layer and the second stainless steel layer are compositely connected through hot-pressing brazing. A manufacturing method of the multi-layer composite cookware comprises the following steps: S1, preparing the energy storage layer; S2, multi-layer compounding; S3, die casting; and S4 spraying.

Description

technical field [0001] The invention relates to the technical field of pot processing and manufacturing, in particular to a multilayer composite pot and a manufacturing method thereof. Background technique [0002] In recent years, as people's living standards have become higher and higher, the requirements for healthy and environmentally friendly pot materials have become higher and higher, and there are increasing concerns about problems such as sticking, rust, and poisoning of metal pots and utensils. [0003] Composite material pots have become the development trend of pots. For example, stainless steel pots with composite bottoms have the advantages of uniform heat transfer, fast heating, and good cooking effects; The method of bonding, the bottom of the pot of this method is easy to delaminate and affect the use effect. The improved methods include riveting method, thermosolid phase bonding method of convex and concave structure, etc., but the convex and concave holes ...

[0003] Composite pots have become the development trend of pots. For example, stainless steel pots with composite bottoms have the advantages of uniform heat transfer, fast heating, and good cooking effects; The method of bonding, the pot bottom of this method is easy to delaminate and affects the use effect. The improved methods include the riveting method, the thermosolid phase bonding method of the convex-concave structure, etc., but the convex-concave holes or grooves are often difficult to process, and the cost is relatively high. High, the bonding strength is not ideal, and cannot meet the requirements of use
