Industrial kilns are mainly divided into glass kilns, cement kilns, coke ovens, ceramic kilns, etc. So what are the Commonly Used Furnace Brick for Sale and what refractory brick materials are required for these kilns lining?
The refractory material for glass kiln has the functions of resistance to chemical erosion, mechanical erosion, small temperature fluctuation, and high-temperature resistance. The selection of glass furnace refractory brick materials mainly includes the following series:
Al2O3-SiO2 series. Mainly include fireclay bricks and silica bricks.
Al2O3-ZrO2-SiO2 series. Mainly include zircon bricks and fused zirconium corundum bricks.
ZrO2-SiO2 series.
MgO-Al2O3, MgO-Cr2O3, MgO-Sioz series.
Insulation material
Refractory Bricks Materials for Cement Kilns mainly include the following categories:
Alkaline refractory materials. The main types of furnace bricks are magnesia chrome brick, magnesia brick, spinel brick, dolomite brick, and so on. Magnesia-chrome bricks are divided into ordinary magnesia-chrome bricks, direct-bonded magnesia-chrome bricks, and semi-directly-bonded magnesia-chrome bricks.
Aluminum-silicon refractory materials. In addition to general clay bricks and high alumina bricks, it is mainly wear-resistant, alkali-resistant, and temperature-resistant. Special high-alumina bricks have been developed, such as phosphate-bonded high-alumina bricks, wear-resistant bricks, anti-stripping high-alumina bricks, and alkali-resistant semi-acid clay bricks.
Insulation and refractory materials. Mainly include calcium silicate board and lightweight insulation brick.
Refractory Castable. There are mainly high-strength and high-alkali castables, anti-skin castables, low-cement refractory castables, special castables for kiln mouths, castables for coal injection pipes, and special castables for tertiary air ducts, and wear-resistant castables.
Refractory brick materials for ceramic kilns.
The material of the inner wall of the kiln wall requires high-temperature resistance, and the type of refractory material selected is determined by the baking temperature of the product.
Use clay refractory bricks at temperatures below 1300 °C.
Refractory brick material for carbonization chamber. Most of the clay bricks were used in the past, but now they tend to use high-quality high-alumina bricks, sillimanite bricks, and andalusite bricks for masonry.
Refractory brick material for combustion chamber. The combustion chamber and the carbonization chamber share the same furnace wall, and the bricks used are the same as those of the carbonization chamber.
Refractory brick material for furnace top. Due to large temperature fluctuations around the coal loading hole on the top of the furnace, clay bricks are used, and other parts are built with silica bricks.
Refractory brick material for the ramp. The chute connects the combustion chamber with the regenerator, requiring the brick body to be stable in structure and resistant to thermal stress. Clay refractory bricks are used for small coke ovens, and silica bricks are used for large and medium coke ovens.
Refractory brick material for regenerator. The single vertical wall, partition wall, bottom, and lattice brick masonry of the small coke oven regenerator are all built with clay bricks. The middle and upper masonry of large and medium-sized coke oven regenerators are all made of silica bricks, so that the whole coke oven can be expanded evenly.
Refractory material for the small flue. The small flue is located at the bottom of the regenerator and communicates with the flue. All small flues are lined with clay bricks.
The above is about refractory brick materials for industrial kilns. Masonry kilns and furnace brick are not only made of one kind of refractory material but also built with a variety of refractory materials.
