Kiln refractory clay brick is made from clinker clay by mixing, forming, drying, sintering and machine pressing moulding with good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
This series of high temperature kiln refractory high alumina bricks use special grade aluminum bauxite clinker as the main raw material, supplemented by special additives, high pressure forming and high temperature firing. Refractory bricks alumina has the characteristics of large heat storage capacity and small creep rate.
Zirconium corundum brick is also named AZS brick. It is based on three chemical components of the Al2O3-ZrO2-SiO2 ternary phase diagram and widely used for glass kiln. The glass kiln brick is arranged according to the order of its contents.
High-quality magnesia brick is a product made of high-grade molding and high-temperature firing using first-grade magnesia and high-purity magnesia as raw materials. Magnesia refractory brick has excellent heat resistant and high resistance to alkali slag erosion.
The refractory magnesia chrome refractory brick is a product made of high-purity magnesia and imported chrome concentrate, which is made by adding a small amount of additives and high pressure and high temperature.
Mag carbon bricks are made of fused magnesia, high-purity magnesia and graphite, and are formed by high pressure molding and low temperature treatment. Different grades of mag carbon bricks can be selected according to different smelting conditions , service life in heats and smelting steel grades.
Mullite insulating brick made by CH refractories is JM series according to international standard. Because jm23 insulation brick with smaller bulk density whose strength is not as strong as heavy weight fire bricks, when delivering, CH Refractories will package mullite insulating brick with special packages to protect mullite bricks from damage.
The anchor refractory brick is also called hanger brick. The anchor brick is similar to the material of the furnace lining castable, shaped by machine pressing, high temperature fired,has good thermal shock resistance and high strength,and is used on multiple heating furnaces to achieve good performance.
Light weight fire clay brick is made of local top grade fireclay materials under the high temperature according to the lastest national standard. The temperature in the 1200-1400 ℃. Ingredients are mixed with water made of plastic material or mud, mud with extrusion or pouring shape, 1250-1350 ℃ after dry burning oxidation atmosphere.
Silica refractory brick is fused silica refractory，a acid refractory brick which mainly consisting of tridymite, cristobalite, and a small amount of residual quartz and glass phases. The silicon content is 94% or more. True density of the silicon brick is 2.35g/cm3.
Corundum bricks include fused cast corundum brick, fused alumina corundum brick and sintered corundum brick. fused cast corundum brick is manufactured with commercial alumina and little sodium carbonate and quartz powder fusing in the quartz powder and through process of casting and annealing, and then form the shape and size through machining.
The tap hole clay is used to block the taphole plays an irreplaceable role in ensuring stable and high production of the blast furnace, improving the working strength and environment before the furnace, and prolonging the service life of the blast furnace.
