Abstract

The present invention discloses one kind of high temperature resistant ceramic cooker suitable for use in electromagnetic induction furnace. The high temperature resistant ceramic cooker is produced with the main materials, including lithium-containing mineral material, quartz, kaolin, etc, and through grinding, mixing, forming, drying, glazing and high temperature baking to obtain the ceramic body; coating far infrared radiation layer, electromagnetically inducing eddy flow heating layer and far infrared reflecting layer to the bottom of the ceramic body; and roasting. It has high heat stability, no cracking even in no-water cooking state, high heat utilization rate and long service life. It is especially suitable for cooking in electromagnetic induction furnace.

Description

technical field [0001] The invention relates to a high heat-resistant ceramic cooking utensil suitable for an electromagnetic induction furnace, which can heat and cook food on the electromagnetic induction furnace. Background technique [0002] So far, there are two kinds of cooking cookers commonly used by people: one is metal products, made of stainless steel and cast iron, which can be used on electromagnetic induction cooker appliances, but it is easy to be oxidized, and its heat preservation performance is very poor, and the cooking taste is also bad. Not delicious; the other is common inorganic non-metallic cookware (such as pottery, glass, etc.), but it cannot be used on an electromagnetic induction cooker. A layer of ferrous bottom as a whole is added to the bottom as a magnetic conductive layer, and glaze is filled between the bottom of the ceramic layer and the bottom of the ferrous layer to bond the above two layers. However, the above-me...
