Production method for foam carbon extraordinarily high temperature macrotype hard heat-insulating room

Abstract

The invention discloses a manufacture method of an ultrahigh temperature large hard heat insulation chamber made of foam carbon, which is characterized in that: the foam carbon is used to make the prefabricated blank of a heat insulation chamber; then the prefabricated blank of the heat insulation chamber is bound to a type modulus, which is solidified and demoulded; then a permeation proof film is laid and a corrosion-proof antioxidant is coated; finally the heat insulation chamber is completed after the integral sintering. The invention has the advantages of aiming at solving the problems of the prior domestic high temperature furnaces caused by the adoption of the soft carbon felt life tenure sewing heat insulation chamber, and producing integral, hard, abnormity and large heat insulation chamber in order to meet the needs of the high-tech industries such as alloy, moncrystalline silicon and carbon or carbon composite material and replace the imported heat insulation chamber; in addition, the invention has low cost and simple and practical production method.

Description

technical field [0001] The invention belongs to the technical field of high-temperature furnace heat insulation chambers, and in particular relates to a method for manufacturing a foam carbon ultra-high temperature large-scale rigid heat insulation chamber. Background technique [0002] In recent years, the production of cemented carbide, single crystal silicon, superalloy, and carbon / carbon composite materials has developed rapidly in China. According to incomplete statistics, China currently has cemented carbide sintering furnaces, single crystal silicon furnaces, vacuum smelting furnaces, vacuum heat treatment furnaces, There are more than 100,000 furnace types such as vapor deposition furnaces. These high-temperature furnaces still generally use traditional soft carbon felts as heat insulation chambers. There are some problems as follows: 1. The production and installation process is cumbersome and needs to be "tailored" 1. After "sewing" and then fixing it on the graphi...
