Preparation method of industrial furnace

Abstract

The invention relates to a manufacture method for an industrial kiln. The inner surface of the manufactured kiln body is orderly provided with a fiber bonding additive layer, a refractory fiber bonder layer, a refractory fiber block layer, a high-temperature infrared bonding additive layer and a high-temperature infrared composite liquid emulsified material layer; the refractory fiber bonder can be a high-temperature binder or a high-temperature refractory fiber bonder; the refractory fiber block can be a refractory ceramic fiber block, a aluminum silicate cotton block for heat insulation or a polycrystalline mullite fiber block; the high-temperature infrared composite liquid emulsified material can be a high-temperature infrared coating, a high-temperature infrared radiation coating or a high-temperature infrared energy-saving coating. The working temperature of the industrial kiln manufactured by the invention is 800 to 1600 degrees Celsius; the invention has the advantages of the high temperature resistance, the low heat conducting coefficient, the small heat loss, the small environmental pollution, the complete combustion, the fast temperature rise speed, the low energy consumption, the good heat shock resistance, the antioxidation, the corrosion resistance, no cracking, no peeling, the light weight, the long service life, the less maintenance time and the high labor productivity.

Description

technical field [0001] The invention relates to a manufacturing method of an industrial furnace. technical background [0002] In common industrial production, there is a process of thermal processing and heat treatment, which is necessary for the manufacturing process of many industrial products. The key to this process is the equipment, that is, the industrial furnace. The quality of industrial furnaces directly affects the quality of products, and the quality of furnace walls and hearths in furnaces is one of the main indicators to distinguish the quality of industrial furnaces. For a long time, the main working part of industrial furnaces is the furnace body. The furnace wall of the furnace body is generally made of various refractory bricks, such as ordinary clay bricks, clay refractory bricks, corundum bricks, silica bricks, magnesia bricks, high alumina bricks, light High-quality refractory bricks, etc.; or use various types of refractory castables, lightweight refra...

AI Technical Summary

Problems solved by technology

The above materials have different usage characteristics and advantages, but there are also some disadvantages. For example, in use, the kiln brick joints are easy to loosen and crack, and the castables are easy to crack and peel off, as well as high thermal conductivity and high heat storage. , poor thermal insulation performance, frequent maintenance, resulting in an increase in non-production man-hours, which greatly affects the production progress, especially in industrial furnaces with cumbersome construction, high labor intensity, long processing cycle, and high costs.
