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.
Our high alumina brick is manufactured with selected bauxite chamotte as main material, fired at high temperature by advanced process with strict quality control. High alumina, as the name tells, meaning the content of alumina percentage is higher than 45. And alumina is one of the most chemically stable oxides, it offers excellent hardness, strength and spalling resistance. Our high alumina brick is widely used in industries which need heat insulation, such as the linings of masonry furnaces, hearth and shaft of blast furnaces, ceramic kilns, glass tanks, cement rotary kilns and so on.
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.
