Q:What are the reasons for the spalling of refractory bricks in the production of lime kiln?
Therefore, the choice and masonry of refractory bricks are of vital importance. If there is a brick kiln kiln off block process of reproduction, is now because of the use of refractory brick kiln material mostly three grade high alumina bricks. The content of AL2O3 is about 55%, of which the content of Fe2O3 is about 2%, which is weak, and the alkali corrosion resistance is a little worse. In a containing three grade high alumina bricks in the composition of AL2O3, Si2O3, and other elements also contain K, Na trace, were the most, thus causing the system of the low melting point is very low, even at 1400 DEG C has been liquid phase, and generate CaAL12O19 limestone and calcium feldspar etc.. Form corrosion loss. Therefore, a long time will cause the loss of block. On the one hand, it may be caused by construction.
Q:What are the high aluminum bricks made of?
We specialize in the production of various LeiBao refractory refractory material, such as corundum, zirconia products, alumina hollow ball products, mullite products and so on.
Q:What's the price of high alumina refractory bricks?
The price of high alumina refractory bricks varies greatly according to the content of AL2O3.
Q:Introduction of high alumina brick
Made from alumina or other raw materials of high alumina content; formed and calcined. High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining.
Q:The difference between light high alumina brick and heavy aluminum brick
High aluminum brick is one of the ideal heat insulating material, with high strength, low thermal conductivity, good insulation performance, low price and other characteristics, has been widely used in ceramic tunnel kiln, roller kiln, shuttle kiln, kiln wall, it is also used in various heating furnace coking furnace of iron and steel industry and other thermal equipment heat treatment, lining material, and has broad market prospects.
Q:What are the requirements for Rubble backfill height?
1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.
Q:Difference between low creep high alumina brick and ordinary high alumina brick
The emphasis is on the physical and chemical indexes of low creep and high alumina bricks. The physical and chemical indexes of the high alumina bricks are different, too. They are DRL-1550And LZ-75 perform GB GB/T2988-2012
Q:Density of high alumina bricks
The density of high alumina bricks is determined according to the price. The average density is between 2.3-2.5g/cm3. The higher the density, the higher the price, the higher the aluminum bricks are in the industry. More than 2.4 are required.
Q:How much is one ton / ton of high alumina refractory brick?
The market price of about super high aluminium brick price at 3000 yuan / ton, a high aluminum brick at around 2500 yuan / ton, two high aluminum bricks at around 2100 yuan / ton three grade high alumina bricks at around 1850 yuan / ton for reference, choose to buy the area is not the same as the prices are not the same.
Q:How are the grades of high alumina bricks differentiated?
High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%
