Corundum brick and chrome corundum brick is the petrochemical industry gas furnace and the furnace key refractory lining material. Corundum brick is α-Al2O3 as the main component of the special refractory material, has been widely used in high temperature, high pressure, chemical erosion and mechanical wear serious ammonia gasification furnace, ethylene engineering gas furnace, carbon black reactor and other important petrochemical heat The lining of the device. Chromium corundum brick is pure Al2O3 and Cr2O3 as the main raw material synthesis, compared with pure corundum brick, it has better performance, such as refractoriness, load softening deformation temperature, bending strength, high temperature creep, high temperature volumetric stability And resistance to slag corrosion.

Product Introduction: High alumina brick refers to refractory products with Al2O3 content higher than 48%.It is made of bauxite or other raw materials of high alumina content .The refractoriness of high alumina brick can be more than 1770 C . According to the content of Al2O3, high alumina bricks are usually divided into three grades: Grade I Al2O3 content 75%; Grade II Al2O3 content is 60 75%; Grade III Al2O3 content is 48~60%. Application: High alumina bricks are mainly used for lining blast furnaces, hot blast furnace, electric furnace roofs, blast furnaces,reverberatory furnaces, and rotary kilns. Features: 1.Low creep. 2.Good slag resistance. 3.Strong thermal shock stability. 4.Good erosion resistance.
Our product We have three colours bricks, red, grey and white. Our bricks are handmade and machine made, are sintered by natural clay material, so the fireproof effect of this kind of brick is very good. The size of bricks is 240*55*20mm, but we can cut the brick according to the customer's needs. Our products use machine slice technology to slice the whole brick, divided into brick skin and brick core, as well as triangular brick and corner brick. This kind of bricks can be used to decorate the wall of cafes, houses, hotel and so on. If you need a lot, the price can be negotiated again.

Refractory Fire Bricks With Normal Alumina, High Alumina Contain For Kiln, Floor And Heat And Acid Resistance
Mullite Brick is a refractory material characterized by excellent performance (especially high temperature creep performance), is made from pure mullite and also alumina powder is added according to different types, finally sintered at high temperature. The features of our mullite bricks are with high mechanical intensity; high refractoriness, contact with flame directly; high porosity, low volume density, low thermal conductivity; low creep rare at high temperature, good thermal shock stability; chemical corrosion resistance and long service life.
ZS Refractories offers you high quality fireclay refractory brick with competitive prices. It is mostly used refractory brick in the iron & steel industry, glass industry, non-ferrous industry, cement industry, pottery kilns and many other industries. With the advantage of its lower cost, the main chemical components of fireclay brick are SiO and Al. And the main raw materials are heat resistant bonding clays and fired clays.
Silica brick is a kind of acid refractory mainly made from tridymite, cristobalite and a small amount of residual quartz as well as glass phase. The raw refractory material is natural silica sand whose SiO2Â content should be more than 96%. The higher SiO2Â content in silica sand, the higher temperature silica bricks resist, its refractoriness under load is as high as 1640 ~ 1670. Glass kiln silica brick has high temperature and volume stability, no pollution to glass liquid, chemical corrosion resistance, small bulk density, and can reduce the weight of furnace body. It also has the ability of resistance to acidic and alkalic steam attack with high performance of flushing resistance. It is mainly used to build the doghouse crown, suspended wall of channel, top crown and inlet sealing, and also to be used to build the checker chamber, chute, combustion chamber, coking chamber and furnace arch in glass melting furnaces. Silica brick has good corrosion resistance to glass liquid. It is the preferred refractory for crown construction of glass melting furnaces, in terms of cost, strength and of defect potential.
Zircon brick is an acid refractory brick with the advantages of good slagging resistance, mechanical strength, high refractoriness under load, excellent thermal shock stability, good creep resistance and good corrosion resistance to glass liquids. Our zircon brick is made from stable zircon sand, it is widely used in the high erosive zones of glass furnace, non-ferrous metal smelting furnace, pure steel furnace, chemical industry, and metallurgy industry, especially used in soda-lime glass kiln as neutral brick, skew brick etc. It is suitable for paving and sub paving, channel blocks as well as sidewall of meter of glass fiber furnace and floating glass tanks.
