Composite steel pan and manufacturing process thereof

Abstract

The invention relates to a steel pan and a manufacturing process thereof, and discloses a composite steel pan and a manufacturing process thereof. The composite steel pan comprises a pan body (1), wherein the pan body (1) comprises an inner working layer (11) and an outer heated layer (12); the inner working layer (11) is covered by the outer heated layer (12); bosses, which are used for increasing structural intensity, are arranged at the bottom of the pan body (1) and the outer edge of a pan opening; and during manufacturing, sheet stocks are applied with oil, and multiple layers of structures undergo imitated pressing and molding, so that the multiple layers of structures are combined through imitated pressing. According to the manufacturing process provided by the invention, the various layers are closely bonded under high-tonnage pressure; under the effect of the high-tonnage pressure, a material of the pan body flows under a cold-solid state or a heated state, so that density isimproved, a molecular structure is distributed more closely and adhesive force between aluminum alloy and stainless steel or a magnetic-conductive layer material is increased; in addition, the multiple layers of composite steel materials of the pan body are integrally molded, and through a stepped-form strengthening effect between the opening and the bottom of the pan body, the pan body is prevented from getting deformed easily when sprayed and roasted at high temperature.

Description

technical field [0001] The invention relates to a steel pan and a manufacturing process thereof, in particular to a composite steel pan and a manufacturing process thereof. Background technique [0002] At present, common composite steel pans in the prior art are as Figure 1-2 As shown, it includes an inner layer (4), an intermediate layer (5) and an outer layer (6), the inner layer (4) is an operation layer, the middle layer (5) is a heat conduction layer made of a magnetically conductive material, and the outer layer ( 6) It is the heat-receiving layer, the outer layer (6) and the middle layer (5) are both located at the bottom of the inner layer (4), and a gap is formed at the outer edge of the joint, which makes it easy to fall off, easy to seep water, and difficult to pass the concave test In addition, multi-layer composite steel pots are formed by ordinary stamping such as stretching and spinning. The body of the pot will be deformed due to spraying and high-temperatu...

AI Technical Summary

Problems solved by technology

[0003] The invention aims at the problem that the pot body in the prior art is deformed due to spraying and baking at high temperature, which affects the appearance quality of the product, and the high-temperature deformation of the bottom plate leads to the failure of the bottom concave test, and provides a composite steel pot and its manufacturing process
