Manufacturing method of induction heating ceramic tableware

Abstract

The invention discloses a manufacturing method of induction heating ceramic tableware. The manufacturing method comprises adding a liquid into porcelain clay or pottery clay to obtain ceramic blank clay, adding a liquid into a conductive metal oxide, carrying out stirring to obtain composite conductive metal oxide blank clay, coating the composite conductive metal oxide blank clay with the ceramic blank clay to obtain composite conductive blank clay blocks, putting the composite conductive blank clay blocks into a steel mold, carrying out rolling depression by a rolling depression device to obtain a blank mold, carrying out drying and sintering on the blank mold to obtain a dried blank mold, carrying out shaping sintering on the dried blank mold, carrying out glazing, and carrying out high temperature sintering to obtain the induction heating ceramic tableware. The metal oxide in the induction heating ceramic tableware has magnetism, can induce an external AC electromagnetic field and form eddy currents, has resistance effects of the metal oxide and can realize transformation of the eddy currents into heat so that non-contact heating effects are obtained.

Description

technical field [0001] The invention relates to a manufacturing method of induction heating ceramic tableware, in particular comprising composite metal oxide clay that can generate heat by inducting an external AC electromagnetic field. Background technique [0002] In many dining occasions or specific meals, tableware or pots with heating, heat preservation or cooking functions are required to maintain the special flavor and taste of the meal itself, such as when eating steak, teppanyaki, and hot pot. Taking steak as an example, the general practice is to use a pre-heated iron plate to a high temperature and place it on a wooden concave plate, and then fill it with the steak meat that has just been cooked and the temperature is quite high. , often use specific vegetables to spread under the steak as a substrate. However, the temperature of the iron plate is very high, which is potentially dangerous, especially it is easy to cause burns to children. For hot pots that requi...

Problems solved by technology

[0010] Therefore, currently commonly used commercially available induction cooker pots include iron pans, iron pans, cast iron pots, stainless steel pots, iron pots, stainless steel pots, and enamel pots (Enamel). Among them, the appearance of iron metal pots is gray and bright. , the texture is low, not suitable for direct use on the dining table, and although the enamel pot itself has the mechanical strength of metal and the smoothness of enamel, and has the characteristics of corrosion resistance, wear resistance, heat resistance, and beauty, enamel is easy to be damaged Collision, falling and damage may cause a considerable degree of harm
