High alumina firebricks are classified according to the alumina content which is from lowest 48% to highest 95%, manufactured from mineral of bauxite, corundum, etc. By mixing, press-forming, drying, sintering and machining. High alumina bricks feature stable mechanical strength and thermal shock resistance, with high refractoriness of no lower than 1880¡æ, high alumina bricks are commonly used as refractory lining exposed to heat directly or backup insulation linings in various types of industrial kiln or laboratory furnace.

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

Like wax candles, Rouseki (Pyrophyllite) is white and semi-transparent, and has a waxy texture when touched. It is very brittle, and tends to crack largely along the stone joints. Up close, this stone looks grayish white, but may look blue from a distance. The ore looks so similar to pottery stone ore that they cannot be distinguished. But there is a difference in their texture, color, and how they crack, and with experience, their differences become more visible. They not only look and feel different, but their applications and properties also differ significantly. It's used as Firebricks, crucibles, glazes, fire-resistant powders, etc.
