Abstract
Description
Technical field:
[0001] The invention relates to an electromagnetic heating layer and a manufacturing method thereof. Background technique:
[0002] There are two types of existing electromagnetic heating layers for ceramic containers: one is stainless steel, and the heat transfer effect of this electromagnetic heating layer from stainless steel to ceramic containers is poor, and stainless steel is easy to lose heat after being cooled and expanded during use. The ceramic container falls off; the other is to adopt a ceramic material with electromagnetic heating properties to sinter on the bottom of the ceramic container to form, this electromagnetic heating layer, as disclosed in Chinese patent application 200610052119.9, is made of iron, silver and melting point adjustment materials (such as Bismuth oxide) and surface tension adjusting materials (such as boric acid), in which iron is the main substance, accounting for more than 70%. During production, the above substances ar...
