Fused Cast Blocks/bricks

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.

Zircon Corundom Mullite bricks are made of raw materials such as high-grade mullite grog and Australia imported zircon sand, which is melted and casted in high temperature electric furnace. It is mainly used in areas that require high abrasion and temperature resistance, such as gliding rail bricks in steel pusher metallurgical furnace, the tapping platform (tapping spout) fortapping platform (tapping spout)style walking beam furnaces, and also as the interior for destructors.

Our fused cast AZS #41 block has the most corundum-baddeleyite eutectic crystals among the electro-fused Al2O3-ZrO2-SiO2 series products. Its corrosion resistance is the best and therefore its normally recommended to be used in quick wear positions to prolong the furnace life. It is the most widely used material both in glass contact and superstructure of glass melting furnaces. Mainly applicable for sidewalls, doghouses, throat, bottom budding, dam blocks, electric block corners, and also linings of furnace in industries. Our product has passed ISO international certification, it is made from high pure material, fired at high temperature by advanced technology, with the advantages of high strength, high compression resistance, good thermal shock resistance, good performance in high temperature, good thermal conductivity, good erosion resistance and so on. This product is available in a large size straight and special shapes which are available for special machining processes. We basically have three casting methods: PT, ZWS and WS, different required castings are manufactured accordingly.

Besides having the similar eutectic crystal as AZS#33 block, our AZS#36 block has more free baddeleyite crystals in chain structure and less vitreous phase, which further improving the corrosion resistance and reducing the potential defects, therefore, the erosion resisting of our AZS#36 block is further strengthened, it is recommended to be used in areas where melting glass flows faster and the temperature is higher, such as melter sidewall, paving, doghouse, etc. We basically have three casting methods: PT, ZWS and WS. 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.

Our fused cast AZS#33 block has dense micro structure which ensures its good resistance in glass liquid. It is widely applied to glass furnace for superstructure, working pool side wall, paving blocks, feeder channels, tank bottoms, c-shaped block and doghouse crown,etc. AZS#33-PT NORMAL FILLING Normal Filling (PT) fused cast AZS#33 block is most widely used in working end, feeder channel, superstructure and top crown parts. Recommended Application: superstructure, working end and feeder channel .etc. Shapes and Size: � It can be made into different shapes and sizes,� such as feeder channel bricks, peephole, tuck stone, crown , blast nozzle bricks. AZS#33-QX ORIENTED CAVITY Oriented Cavity ( QX ) AZS 33# block is most widely used in glass melting furnace side wall part . AZS#33-WS VOID FREE Void Free (WS ) AZS-33 # block is most widely used in sidewall, tank bottom, feeder channel, c-shaped bricks, Doghouse crown, superstructure .

AZS Bricks, Alumina-Zirconia-Silica (AZS) refractories, belong to sintered ZrO2_Al2O3_SiO2 products family along with Zircon Mullite, Bonded AZS, Zirconia Corundum, and Rebonded Fused Mullite bricks. Sintered ZrO2-Al2O3_SiO2 products such as AZS have good resistance to alkali vapor and thermal shock. Mainly used in glass furnaces, they can withstand aggressive conditions in contact with molten glass. Typical applications are superstructures, skew blocks, wall bricks and upper-checker in regenerators, paving, sub-paving, and forehearth blocks in float glass furnaces. Our fused AZS blocks mainly inclue model AZS-33#, AZS-36#, and AZS-41#. the different models applicated in different parts of furnaces. AZS brick 33#, a normal refractory material, with the features of very good melting glass resisting, which seldom produces stone or other faults, and has little possibility to produce bubbles, widely used in glass Industrial furnace. AZS brick 36# has more free baddeleyite crystals in chain structure and less vitreous phase, which further improves the corrosion resistibility and reduces the potential defects in glass, so it is recommended to be used in sections where glass flow is faster and temperature is higher, such as melter sidewall, paving, doghouse, etc. AZS brick 41# has the most free baddeleyite crystals among the fused cast AZS families, which are evenly distgributed within the block. Its corrosion resistibility is the best and thus it is usually recommended to be used in the most demanding positions to balance the furnace life.

The glass is mainly made of silica sand and soda ash as raw materials which are melted at a high temperature. Glass melting furnaces are thermal equipment for melting glass and are usually constructed of refractory materials. Glass melting furnaces can be divided into two categories: pool kiln and crucible kiln. The pool kiln is the most commonly used kiln type in the glass industry. It is made of refractory materials, and has a flame pool kiln and an electric kiln. Casting zirconium corundum bricks are commonly known as white iron bricks. It is the most important refractory material to ensure the normal operation of the glass melting furnace. At present, the melting rate of the glass melting furnace at home and abroad is increased, the kiln age is extended, and the fuel consumption is reduced mainly due to the use of the refractory material. The use of fused zirconium corundum brick in the glass melting furnace is to build the upper pool wall, small furnace flat raft, small furnace raft, stone raft and chest wall. Fused cast blocks usually named zircon corundum brick also name AZS bricks( alumina zircon silica ),according to the ZrO2 content difference ,can be named AZS 5.5 ,AZS 12 .AZS 33, AZS 36, AZS 41 and so on. Beside because this type bricks are produced by special electric furnace by model, we also called this products Fused cast AZS bricks. Also according to the brick if have shrinkage cavities, we call them PT, QX, ZWS, WS. These bricks are widely used for iron & steel furnace and glass furnace, also chemical industrial furnace, especial in the glass furnace, you will find it usually.
