Manufacturing method of aluminum electromagnetic heating pot

Abstract

The invention relates to the technical field of kitchen ware, in particular to an aluminum electromagnetic heating pot and a manufacturing method thereof. The electromagnetic heating pot comprises a pot body, wherein an oxide layer fully or partially covers the surface of the pot body; a magnetic conductive layer fully or partially covers the pot body or the oxide layer; and a protective layer and / or a heat conductive layer are / is arranged outside the magnetic conductive layer; and the manufacturing method of the aluminum electromagnetic heating pot specifically comprises the following steps: (1) forming the pot body; (2) fully or partially spraying the magnetic conductive layer on the surface of the pot body, wherein the magnetic conductive layer is made from a magnetic conductive metal material; and (3) spraying the protective layer and / or the heat conductive layer which cover / covers the outside of the magnetic conductive layer, wherein the protective layer and / or the heat conductive layer are / is made from a metal or non-metal material; and before the step (2) or after the step (3), fully or partially oxidizing the pot body. The electromagnetic heating pot is low in cost, easy for processing, good in corrosion resistance, excellent in spraying performance and is durable and wear-resistant.

Description

technical field [0001] The invention belongs to the technical field of kitchen utensils, and in particular relates to a preparation method of an aluminum electromagnetic heating pot. Background technique [0002] Induction cooker is also known as induction cooker. In 1957, the first household induction cooker was born in Germany. In 1972, the United States began to produce induction cookers, and in the early 1980s, induction cookers began to sell well in Europe, America and Japan. The principle of the induction cooker is the phenomenon of electromagnetic induction, that is, the alternating current is used to pass through the coil to generate an alternating magnetic field with a constantly changing direction. Eddy currents will appear inside the conductor in the alternating magnetic field, which is the eddy electric field that drives the current-carrying in the conductor. The Joule heating effect of the eddy current heats up the conductor, thereby achieving heating. [0003...

AI Technical Summary

Problems solved by technology

Cookware made of other materials will cause abnormal load on the induction cooker and start automatic protection due to the material resistivity is too large or too small, and cannot work normally.

[0005] Existing materials for pots used in induction cookers, such as iron and magnetically conductive stainless steel, can be heated by induction, but they are expensive, difficult to process, poor in corrosion resistance, and poor in spraying performance. However, the existing aluminum alloy pots are low in cost and easy to use Good processing, spraying performance, and good non-stickiness, but it cannot be heated by electromagnetic induction
