Problems solved by technology

[0004] The purpose of the present invention is to provide a magnetically conductive ceramic pot and its preparation process, which solves the need to process brittle ceramics in existing ceramic pots, such as punching holes and scribing grooves, etc., so that the yield of ceramics is very low and the process is complicated; in addition, metal magnetic There is a big difference between the thermal expansion and cold contraction of the sheet and the ceramic body. When sintered at high temperature, the metal magnetic sheet is prone to severe oxidation, and the outer ceramic is heated and cracked.

Abstract

The invention relates to a magnetic conductive ceramic pot and a preparation process of the magnetic conductive ceramic pot. The magnetic conductive ceramic pot comprises a ceramic pot matrix, a magnetic conductive anti-oxidation heating plate and a ceramic sealing sheet, wherein a groove is formed in the bottom of the ceramic pot matrix, the magnetic conductive anti-oxidation heating plate is arranged in the groove in the bottom of the ceramic pot matrix, and the size of the magnetic conductive anti-oxidation heating plate is smaller than that of the groove in the bottom of the ceramic pot matrix; the ceramic sealing sheet is sealed to the bottom of the ceramic pot matrix; the magnetic conductive anti-oxidation heating plate comprises a magnetic heating plate and a high-temperature antioxidation coating; the high-temperature antioxidation coating covers the surface of the magnetic heating plate, and after sintering, a closed protective film layer is formed. The preparation process comprises the following steps: preparing blank of the ceramic matrix, carrying out rolling forming, preparing the magnetic conductive anti-oxidation heating plate, preparing the ceramic sealing sheet, embedding the magnetic conductive anti-oxidation heating plate, carrying out sealing, and finally, carrying out sintering. With the adoption of the magnetic conductive ceramic pot, the problem that when the traditional ceramic pot with the metal magnetic conductive heating layer is subjected to electromagnetic heating, since the thermal matching degree between the metal heating layer and the ceramic pot is poor, the swelling, pot breaking and the like are easily caused are solved, in addition, the preparation process is simple, and therefore, the application value is good.

Description

technical field [0001] The invention relates to the field of preparation of ceramic vessels, in particular to a magnetically conductive ceramic pot and a preparation process thereof. Background technique [0002] As a new type of stove in the kitchen utensils market, the induction cooker adopts the principle of magnetic field induction eddy current heating, which breaks the traditional open flame cooking method and has gradually become popular in families. It has the advantages of fast heating, high thermal efficiency, no open flame, no heat radiation and no smoke to the surrounding environment , good security and other advantages, known as the "God of Cooking" and "Green Stove".
