Q: What is the standard classification of high alumina bricks and high alumina bricks?: High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. High alumina brick refractory clay brick and brick than refractoriness to high. It belongs to high refractory. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.According to the number of AL2O3 content is divided into, 55,65, 75,80 and so on several grades.

Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?: Quality requirements for aluminium bricks of different grade. 2, high aluminum powder and high alumina aggregate and other materials of reasonable proportion, to reach the production requirements.

Q: What's the difference between a well type annealing furnace and a box type annealing furnace?: 1. The shell of the furnace is welded by section steel and steel plate. 2, the furnace cover support adopts steel and guide rail combination mobile type. 3. The heating element is made of high resistance alloy 0Cr25Al5 produced by Beijing Shougang Group and arranged on the furnace side. 4, because the bottom bearing adopts high aluminum bricks, the circle center of the furnace set small, inside and outside heating. 5 、 furnace cover adopts hydraulic lifting, motor control, automatic walking. 6 、 temperature control system adopts PID SCR control, high accuracy.

Q: What is the price of the first grade high alumina brick?: Many factories in Xinmi have high alumina bricks, but they must choose a regular factory. Kuwait refractory level high aluminum brick price at around 1600, the quality of double stable supply

Q: How are the high alumina bricks fired?: Generally, the high alumina bauxite is added with a small amount of clay. After being ground, the gas is injected and shaped in the form of slurry by the way of gas attack or foam, and it is burnt at 1300~1500 DEG C. Sometimes industrial alumina can be used to replace part of bauxite clinker. Used for lining and thermal insulation of masonry kilns, as well as for areas where there is no high temperature, high melting material erosion and erosion effects. When touching the flame directly, the touch temperature shall not be higher than 1350 degrees.

Q: The cloth blowing is not uniform on the lime kiln refractory brick is damaged it: People with the shaft kiln cement clinker kiln, because of small size, low calcination temperature, using only Al2O3 containing a single clay brick is 30 ~ 40%, the rotary kiln was improved in the early Yuan faith this experience, use of high alumina brick and clay brick, from 60s onwards, due to large scale kiln and to strengthen the operation of the high temperature parts of kiln lining, alkaline brick masonry is widely used, the main varieties are: magnesia chrome brick, magnesia spinel brick and dolomite brick.

Q: How to make refractory bricks and boiler wall adhesion more firm?: Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry

Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.

Q: The difference between light high alumina brick and heavy aluminum brick: Lightweight high alumina brick, also called high alumina insulation brick. Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. Volume density 0.4 - 1.35g/cm3. Porosity 66% - 73%, compressive strength 1 - 8MPa. Better thermal shock resistance. Usually, a high alumina clinker is added with a small amount of clay. After grinding, it is poured and shaped in the form of slurry by gas generation or foam method, and it is fired at 1300 - 1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.

Q: Which thermal shock stability of clay brick and high alumina brick is good?: High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
