Preparation method of ceramic inner pot used with electric heat pan

Abstract

The invention relates to the field of ceramic, specifically to a preparation method of a ceramic inner pot used with an electric heat pan. A blank material of the invention comprises the following ingredients: kaolin, spodumene, petalite, talcum, clay, bentonite and waste ceramic. Glaze is composed of the following ingredients: kaolin, spodumene, petalite, magnesium oxide and calcium oxide. The preparation method of the ceramic inner pot used with an electric heat pan comprises the following steps: preparing for raw materials of the blank material and glaze, preparing the blank material and the glaze, cleaning and drying a plaster mold, moulding by rolling the standby blank material, fettling with a small steel knife to prepare a moulded product, glazing with the standby glaze, and sintering the glazed product with a kiln to obtain the ceramic inner pot used with an electric heat pan. The invention aims to provide a preparation method of the inner pot used with an electric heat pan. The ceramic inner pot has advantages of high qualified rate, high regularity, flat and smooth glaze layer, good fit between the bottom and wall of the pot and an arc-shaped heating element of the electric heat pan and good heat conduction effect.

Description

technical field [0001] The invention belongs to the field of ceramic utensils, in particular to a method for preparing a ceramic inner pot used in conjunction with an electric heating pot. Background technique [0002] Electric hot pot is a kind of electric cooking utensils. The metal heating element in the electric heating pot is energized to generate heat, and the heat is transferred to the inner pot fitted with the heating element, and the food in the inner pot is cooked. At present, electric heating pots are often equipped with ceramic inner pots to make food cooking more hygienic and delicious. [0003] The contact part of the heating element of the conventional electric heating pot and the bottom of the ceramic pot is a plane (or a slightly convex plane), and the heat of the ceramic pot is introduced from the bottom of the pot. During the cooking process, if the water content of the food in the pot decreases, the food in the pot will be heated unevenly, and the cooki...

Problems solved by technology

This requires that the shape and regularity of the ceramic pot must meet the strict requirements of the design. The conventional allowable dimensional error range of the ceramic pot becomes smaller, the wall thickness requirements of the ceramic pot also change, and the glaze layer of the ceramic pot should be flat and smooth. , these special requirements lead to the inability of conventional ceramic pot preparation methods to meet the requirements of this special ceramic pot
