low porosity clay bricks are mainly used in the regenerators of glass kilns. They can also be used in blast furnaces and hot blast furnaces in the steel industry; cement kilns in the building materials industry; chemical kilns in the chemical industry as kiln linings
low porosity clay bricks for glass kilns
What kind of low porosity clay bricks are used in glass kilns? Where is it mainly used in the glass kiln? Today we will introduce the low-porosity clay bricks for glass kilns.
Low porosity clay bricks for glass kiln is a kind of refractory clay brick. It is mainly made of high alumina bauxite and coke gemstone as the main raw materials. Low-porosity clay products made by kiln firing after refining, molding and drying, the porosity is generally lower than 17%.
Glass kiln low porosity clay bricks application
Low porosity clay bricks are mainly used in the regenerators of glass kilns. They can also be used in blast furnaces and hot blast furnaces in the steel industry; cement kilns in the building materials industry; chemical kilns in the chemical industry as kiln linings.

Characteristics of low porosity clay bricks
1. Low apparent porosity and strong compactness.
2. Good permeability and corrosion resistance.
3. High temperature strength and long service life.
Fireclay bricks are classified as weak acid refractories. Due to the large fluctuation range of chemical composition, different production methods, and differences in firing temperature, the properties of clay bricks change greatly.We can produce all kinds of Fireclay bricks according to customers' requirements
Fireclay bricksis suitable for supporting hot blast stoves of large, medium and small blast furnaces
The Al2O3 content of clay heat Clay insulating refractory bricks is generally more than 40%, and the Fe2O3 content is less than 2.0-2.5%. The clinker in the ingredients is 65-85%, and the combined clay is 35-15%. The crushed bonded clay and the finely ground clinker are mixed and milled, and then mixed with the granular clinker to make semi-dry mud, high pressure molding, and sintering at about 1400 ℃, with good performance.
The refractoriness of clay bricks is comparable to that of silica bricks, up to 1690~1730℃, but the softening temperature under load is more than 200℃ lower than that of silica bricks. Because in addition to the high refractory mullite crystal, the clay brick also contains nearly half of the low melting point amorphous glass phase.
Anhydrous tap hole mix for blast furnace tap hole
The alkali-resistant brick for cement kiln has the characteristics of strong alkali erosion resistance, good thermal shock resistance and high cost performance.
Refractory ramming mass (refractory taphole mass) is a kind of Refractory used for lining of blast furnace tapping groove. It is mainly used to protect the blast furnace out of the ditch from high-temperature hot metal and slag erosion and erosion, and has excellent high-temperature resistance and wear resistance. The ramming material for the iron discharge ditch is usually composed of corundum, silicon carbide and carbonaceous material, which has the ability of resisting hot metal and molten slag erosion and scouring, reburning line change small, strong resistance to a variety of oxidation characteristics. The construction of the ramming material for the iron ditch is convenient, easy to dismantle and repair, does not produce harmful gas, and is beneficial to environmental protection.
Insulation castables are mainly made up of lightweight refractory aggregates, powders, and binder additives.
