Our AZS#36 block has features of strong glass corrosion resistance and high thermal shack stability; good RUL, wear-resistance, dregs-resistance and alkali corrosion resistance; moreover, our product is adopting superior material, with process by special arc furnace forming, thus such fused cast technology has almost no suffer from electrode pollution.
Fused cast magmalox block, also named fused cast wear-resistance block, fused cast skid rail block, and fused cast zirconia mullite block.
ZS Refractoriesâ?? fused cast magmalox block uses high quality bauxite, zircon sand and other raw materials, melting in an electric arc furnace at a high temperature ranging from 2000-2500�°C. The molten product then casted in molds, and kept to anneal for almost two weeks.
It has advantages of compact structure, wear-resistance, impact resistance, strong thermal shock resistance, good corrosion resistance, slag resistance, and long service life. Being applicable in the areas of metallurgical pusher type reheating furnace, steel outlet tank, the lining of refuse incinerator, our fused cast magmalox block is also served as the key part of glass melting furnace.
Fused cast alumina block is also called fused cast block. As a kind of very important assisting refractories used in glass furnaces, it is composed of Alumina, Alumina and small amount of glass phase. It has superior corrosion resistance at the temperature up to 1350 C, zero bubble rate and pollution free to molten glass. It is also an ideal material for sidewall, paver of cooling zone/working end and the float canals of high quality glass furnaces.
It is produced by melting and casting high purity alumina in electric furnace at 2000 corundum product is formed when alpha alumina and beta alumina inter-combine during their crystallization stage. In contact with molten glass, alpha beta alumina barely produces any blistering or stones. Therefore, alpha beta alumina blocks may be widely used in glass contact end zones of furnaces when glass quality is the priority.
According to alumina content difference, fused cast alumina block can be categorized to fused cast (alpha) alumina block, fused cast (beta) alumina block, and fused cast block. We have casting method WS (VF) only.
Our bottom block is made from high quality raw material, processed by fine batching, forming, drying and firing process. After that the block will be matched by cutting, grinding, milling and drilling to assure of the accurate sizes.
The physical and chemical properties of our bottom block are excellent, the appearance and size are accurate, especially the anti hydrogen diffusion ability and anti alkali erosion ability of the product are remarkable.
This block can be used in the whole bottom of floating glass tin bath.
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.
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.

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.
The series of insulating refractory bricks supplied by our ZS Refractories are assigned to the group of lightweight refractory bricks and are manufactured on the basis of naturally occurring lightweight raw materials, including high alumina light weight insulation brick, fire clay insulation brick, silica insulation brick, mullite insulation brick and so on.
