Industrial Kiln Refractory Materials For Sale

What are the classifications of Industrial Kiln Refractory Materials For Sale? Generally speaking, according to the type of industrial kiln, the refractory for industrial furnace is mainly divided into refractory for glass tank kiln, refractory for cement kiln, castable for ceramic kiln and refractory for coke oven, etc.

RS Manufacturer Refractory Castable Production Line

Rongsheng refractory manufacturer produces and sells various refractory materials for industrial furnaces. For different industrial furnaces, RS can customize refractory materials for them according to the production and working environment of different industrial furnaces. The following is a brief introduction of some refractory materials for industrial furnaces.

1, Refractory for Glass Tank Kiln

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

Glass Furnace Refractory Lining

(1) Al2O3-SiO2 series; mainly includes clay bricks and silicon bricks.

(2) Al2O3-ZrO2-SiO2 series; mainly include zircon bricks and fused zircon corundum bricks (AZS Bricks).

(3) ZrO2-SiO2 series;

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

(5) Insulation materials, including insulation bricks and ceramic fiber cotton series.

2, Refractory Materials for Cement Kilns

Refractory materials for cement kilns are a variety of materials and should be used in combination. There are the following categories:

Cement Rotary Kiln Refractory Materials

(1) Alkaline refractory:

The main varieties of alkaline refractory materials are: magnesia chrome brick, magnesia brick, magnesia spinel brick, dolomite brick and so on. Magnesia-chrome bricks are divided into ordinary magnesia-chrome bricks, directly combined magnesia-chrome bricks, and semi-directly combined magnesia-chrome bricks.

(2) Aluminum silicon refractory:

Aluminum silicon refractory for cement kiln, except general clay brick and high alumina brick. There are also special requirements: mainly the change of wear resistance, alkali resistance and temperature resistance. According to these special needs, RS refractory manufacturer has developed special high-alumina bricks specifically for cement. Such as phosphate-bound high-alumina bricks, phosphate-bound high-alumina wear-resistant bricks, anti-stripping high-alumina bricks, and alkali-resistant semi-acid clay bricks.

(3) Insulation and refractory materials: mainly including calcium silicate board and lightweight thermal insulation brick.

(4) Castable:

The refractory castables for cement kiln include high-strength and high-alkali castables, crust-resistant castables, low-cement refractory castables, kiln mouth special castables, coal injection pipe castables, tertiary duct special castables and wear-resistant castables.

3, Refractory Castable Material for Ceramic Kiln

The refractory castable materials of the inner wall of the kiln wall require high temperature resistance, and the type of refractory used is determined by the temperature at which the product is fired.

(1) Use clay refractory bricks at temperatures below 1300 ° C;

(2) Use high alumina brick at 1300 ～ 1400 ℃;

(3) Use silicon brick at 1400 ～ 1500 ℃;

(4) Use magnesia-aluminum brick at 1500 ～ 1600 ℃;

(5) Use corundum bricks below 1800 ° C.

4, refractory for coke oven

(1) Refractory materials for the carbonization chamber; most of the past used clay bricks, but now tend to use high-quality high alumina bricks, sillimanite bricks and andalusite bricks.

(2) Refractory materials for combustion chambers. The combustion chamber and the carbonization chamber share the same furnace wall, and the bricks are the same as the carbonization chamber.

(3) Refractory for furnace roof. Because of the large temperature fluctuation around the coal hole on the top of the furnace, clay bricks are used for the construction, and other parts are made of silicon bricks.

(4) Refractory materials for ramps. The ramp connects the combustion chamber with the heat storage chamber, and requires the brick structure to be stable and able to resist the effects of thermal stress. Clay refractory bricks are used for small coke ovens, and silicon bricks are used for large and medium coke ovens.

(5) Refractory materials for thermal storage rooms. The small vertical wall, partition wall, furnace bottom and lattice brick masonry of the small coke oven heat storage room are all made of clay bricks. The middle and upper masonry of large and medium-sized coke oven heat storage rooms are all made of silicon bricks. In order to make the coke oven as a whole expand uniformly.

(6) Refractory for small flue. The small flue is located at the bottom of the heat storage chamber and communicates with the flue. The small flues are all lined with clay bricks.

5, Refractory materials for fluidized bed incinerators

The incineration temperature of the cfb bed incinerator is 750 to 870 ° C. Because the materials (carrier and waste residue) in the furnace circulate in a boiling shape, the lining material requires heat-resistant and wear-resistant refractory materials. 

CFB Boiler Refractory Lining

• The furnace is made of heat-resistant and wear-resistant concrete with a total thickness of 250mm. 
• The inner layer uses 150mm lightweight heat-resistant concrete as the heat insulation layer. 
• The outer layer (working layer) is cast with 100mm thick aluminophosphate concrete (alumina clinker: low calcium aluminate cement: fine aluminum hydroxide powder: aluminum phosphate solution 100: 25: 25: 20 ～ 24 (Wt)) Or use lightweight insulation bricks and first-grade high alumina bricks (L2-65) for masonry.
