Industrial furnaces for the use of refractory materials

In the industrial industry, there are many choices of kiln in various industries. The classification of refractory materials is also very important, so what are they divided into? Generally speaking, it is mainly divided into four types: refractory materials for glass pool kiln, refractory materials for cement kiln, castable materials for ceramic kiln, and refractory materials for coke oven. For details, please continue to look down:

 

1. Glass pool kiln refractory.
 

According to the working environment of the glass tank kiln, the factors that cause the kiln lining damage are comprehensively considered: chemical erosion, mechanical scouring, degree fluctuation and high temperature action. The selection of kiln materials mainly includes the following series:
 

(1) Al2O3-SiO2 series; mainly consists of clay bricks and silica bricks.
 

(2) Al2O3-ZrO2-SiO2 series; mainly including zircon bricks and fused zirconium corundum bricks.
 

(3) ZrO2-SiO2 series.
 

(4) MgO-Al2O3, MgO-Cr2O3, MgO-Sioz series.
 

(5) Insulation material.

2. Refractory materials for cement kiln.
 

The refractory materials used in cement kiln are multi-species materials and should be used in combination. There are mainly the following categories:
 

(1) Alkaline refractory materials; basic refractory materials include: magnesia chrome bricks, magnesia bricks, spinel bricks, dolomite bricks, etc. Magnesia chrome bricks are divided into ordinary magnesia chrome bricks, direct combination magnesia chrome bricks, and semi-direct combined magnesia chrome bricks.
 

(2) Aluminium-silicon refractory materials; aluminum-silicon refractories for cement kiln, in addition to general clay bricks and high-alumina bricks, have special requirements. Mainly wear-resistant, alkali-resistant, temperature-resistant changes, for this purpose has developed a series of special high-aluminum bricks, such as phosphate combined with high-aluminum brick, phosphate combined with high-aluminum wear-resistant brick, anti-flaking high-aluminum brick and resistant Alkali semi-acid clay bricks, etc.
 

(3) Insulating refractory materials; mainly including silicic acid cover plates and lightweight thermal insulation bricks.
 

(4) Castables. The castables for cement kiln include high-strength and high-alkali castables, anti-skin castables, low-cement refractory castables, kiln-specific castables, coal injection pipe castables, tertiary air duct special castables and wear-resistant castables.
