The refractory basic alumina silicon insulation brick is applying for thermal kiln or furnace of copper smelting, clinker / cement sintering, lime sintering production line. Basic brick is using at sintering zone. Alumina silicon brick is using at non-sintering zone. Insulation brick is using at insulation layer of equipment or giant pipes.
Refractory bricks.
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.

Fused cast azs block has strong glass corrosion resistance and high thermal shack stability. The products are adopting superior material, with process by special arc furnace forming it. This fuse cast technology got nearly no suffers from electrode pollution. Application Can be used at parts where chemical erosion is serious and temperature changes frequently, such as fire spurting mouth and regenerator joints, end port of furnace etc Wooden pallets
1.Description High alumina fire brick contain al2o3 more than 48%, which is made of high grade bauxite through high temperature calcinations. Its refractories is usually above 1770 ¡ãc. The main mineral components are corundum and mullite phases. It is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. According to al2o3 content, it can be divided into three degrees:the al2o3 content is more than 75%.The al2o3 content range from 60% to 75%.The al2o3 content range from 48% to 60%. 2.Feature 1. High-temperature endurable . 2.Good thermal shock resistance. 3.High cold crushing strength 4.Good resistance to abrasion and corrosion. 5.Good thermal spalling resistance. 6.High mechanical strength. 7.Good volume stability at high temperature. 3.Applications High alumina fire brick is used for building blast furnaces, hot blast stove, electric stove roof, ladle, blast furnace and reverberatory furnace, lining of rotary kiln and glass kiln and chemical industrial kiln. In addition, high alumina brick is widely used as regenerative checker brick of open hearth, pouring system with the plug head, nozzle brick, etc. On wooden pallets with plastic cover Pallite size:1.05*1.05m
this series of bricks are made from high quality fused MgO,fused corundum and graphite as main raw materials and phenolic resin as binder . the products are mainly used in the bottom and sidewall of ladle with better corrosion and erosion resistance.
