Problems solved by technology

However, the structure of pores and gaps on it is complex, and the production cost is high
In addition, the structure of pores and gaps is likely to bring stress concentration to cooking utensils, which affects the service life of cooking utensils
More importantly: the body of the cooking utensil adopts a single-layer structure, and the structure does not heat quickly and evenly; the heat storage is not durable, and cannot meet the needs of the market

Abstract

The invention provides a method for producing composite cooking tool, and relative method, for resolving the problems as low thermal efficiency, long cooking time and short service life. The inventive method comprises that A, producing body of cooling tool as a, material selection, cold rolling, b, washing, drying, c, roller pressing, d, drawing, B, returning bottom as a, washing, drying, b, thermally forging or solder welding, c, surface treatment. The inventive composite cooking tool comprises a body and a bottom plate, wherein the bottom plate has welded metal plate and metal sheets from inner to outer via thermal forging or solder welding, the body has two or three metal layers welded via thermal forging or solder welding, and the body and the bottom plate are welded together via thermal forging or solder welding. The invention has simple process, low cost, uniform heated and long service life.

Description

technical field [0001] The invention relates to a method for making a cooking utensil and its products; in particular, it relates to a method for making a composite cooking utensil applied to an electromagnetic oven and its products; it belongs to the technical field of kitchen utensils. Background technique [0002] The existing cooking utensils, especially the cooking utensils applied to the induction cooker, because the pot body of the cooking utensils is usually made of aluminum or stainless steel, absorbs relatively small electromagnetic waves emitted by the induction cooker, resulting in low thermal efficiency of the cooking utensils during use. , high power consumption, long cooking time and other defects. [0003] In order to overcome these defects, someone has designed a cooking utensil with a composite structure at the bottom, which adds a layer of stainless steel material with strong magnetic flux capability at the outer bottom of the pot body, thereby improving t...
