Light High Alumina Brick Definition
 
The lightweight high alumina brick has an alumina content of 48% or more, Which is a refractory product having a porous structure mainly composed of mullite and a glass phase, or a corundum phase and a glass phase. Light weight refractory bricks performance is superior to lightweight silica bricks and lightweight clay bricks. Lightweight high alumina bricks and light corundum bricks made from industrial alumina and high alumina bauxite have a refractoriness of up to 1800 ° C and a maximum temperature of 1 650 ° C.

Light High Alumina Brick Advantage
 
1. Economical
 
Lightweight high alumina brick can reduce the cost of the foundation, reduce the cross section of the frame, and save the reinforced concrete can significantly save the overall cost of the building. The design uses light fire bricks compared to solid clay bricks, the overall cost can be reduced by more than 5%.
 
2.Practicality
 
The use of lightweight bricks can increase the use area. At the same time, due to the heat insulation of aerated concrete, the insulation alumina bricks effect is good. In the hot summer, the indoor temperature is 2-3 ℃ lower than that of solid clay bricks. Reduce power consumption.
 
2. Construction
 
Light high alumina fire bricks has good machine ability, the construction is convenient and simple. Due to the large size of light fire bricks and light weight, light high alumina fire bricks can reduce labor intensity, improve construction efficiency and shorten construction period.

Light High Alumina Brick Manufacturing Process
 
High Alumina Lightweight Brick Manufacturing Process by Foam Method
 
1.The heavy grade high alumina bauxite mill with A12O3 content of about 55% and the combined fire clay with A12O3 content of 31-32% are used as raw materials.
 
2.A foaming agent is prepared using sodium rosinate. Sodium rosin foam is made by saponification of rosin and alkali, then formulated into a stabilizer bone cement solution.
 
3. The casting of lightweight high alumina bricks is carried out on iron plates placed under a porous aluminum mold. The inner wall of the model is made of 5-6 layers of paper. The molding mud is slowly injected into the mold until it is full. Also, the vibration is slightly increased to make the green body uniform and reduce cracking.
 
4. The green body of light refractory bricks can be demolded after drying at 35-45 ℃ for 24 hours; after 7 days, the body moisture is less than 1%. light weight alumina brick is fired in the kiln at 1300-1340℃.
 
High Alumina Lightweight Brick of Flammable Addition Method
 
1. Light refractory bricks having a bulk density of 0.8 can also be produced by adding a combustible material to the mud. The combustible characters used in production include sawdust, rice husk, coke powder and anthracite. The requirements for flammable additives are that they are easily burned out, the ash content is low, and the amount of harmful impurities in the ash is small. Generally, sawdust and rice husk are used, and the amount of addition is generally 30-40%. The sawdust is sieved; the rice husk can be co-milled with high alumina bauxite. The mud and the combustible plus characters are mixed in a wet mill for 4-5 minutes, or extruded into a mud strip by a screw extruder. The moisture content of the mud is 40-50%.
 
2. The mixed mud can be molded in a wooden model. The wood model is first wetted with water, brushed with sawdust, then filled with mud, smoothed and demolded. After the body of light high alumina insulation brick is dried, light weight alumina bricks are fired at the required temperature.
 
Light High Alumina Brick Using Precautions
 
Light high alumina insulation brick strength is large and the high temperature re-sintering shrinks. Light refractory bricks have low compressive strength, poor slag resistance, poor heat resistance and cannot be in direct contact with glass solutions or flames.
 
Insulation Lightweight Fire Bricks Classification
 
Three Types of Insulation Bricks
 
1.Ordinary insulation bricks, the use temperature is below 1000 °C, mainly diatomite bricks, expanded perlite bricks. mostly used as thermal insulation layer of thermal equipment, not directly in contact with flame.
 
2.Refractory insulation bricks, used at temperatures between 1200 ° C and 1500 ° C, refractory insulation bricks can be exposed to flame. There are mainly light clay bricks, light silica bricks and light high alumina bricks.
 
3. The high temperature kiln uses light insulation refractory bricks, the use temperature is above 1500 °C, light insulation refractory bricks can be directly used as the lining of high temperature kiln, mainly light corundum brick, corundum mullite lightweight thermal insulation brick, alumina Hollow ball bricks and products and zirconia hollow ball bricks and refractory bricks products.
