Description

Technical Field

[0002] At present, there are various types of ceramic fiber furnace gallbladders on the market, mainly integrated box-type resistor furnace gallbladders formed by vacuum molding. There are many problems in the manufacturing and use of box-type furnace gallbladders. First of all, since the size of the furnace gallbladder cannot be unified, it is necessary to make corresponding molds according to the required furnace gallbladder size during molding, and the process is complicated. Secondly, uneven vacuum adsorption during molding will lead to inconsistent inner wall strength in all directions of the furnace gallbladder. After long-term use or long-term continuous working, it will cause local cracking and collapse of the furnace. In addition, after working for too long, the internal heating parts of the furnace gallbladder will become brittle, broken, and overlap short-circuited, and it is difficult to replace them after damage. These problems are difficult to repair after they occur, which brings troubles to subsequent use. Ceramic fiber is a fibrous lightweight refractory material with the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and resistance to mechanical vibration.
