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:How to test the aluminium bricks of high alumina refractory bricks?
Forming high alumina brick will be tested on some professional equipment, it is suggested that you can go to the professional testing department to know about it!
Q:What is the heat preservation material used in a laboratory furnace?
Thermal insulation cotton is a high-purity clay clinker, alumina powder, silica powder, chromium sand and other raw materials in the industrial furnace melting at high temperature, forming fluid. Then, compressed air is used to blow or use the wire throwing machine to turn the yarn into a fiber shape. After the cotton collector is collected, the cotton is formed into a heat preservation cotton.The high alumina brick is usually made of high alumina clinker with small amount of clay. After grinding, the high alumina brick is poured and shaped in the form of slurry by the way of gas generation or foam, and it is burnt 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:What is the content of free silica in the refractory bricks of high alumina bricks?
In the meantime, the free silica content of silicon brick is as high as 90% above. Therefore, the most serious damage is silicon brick, followed by clay brick, high alumina brick, magnesia brick and so on.
Q:Refractory brick, high alumina brick, magnesia chrome brick or magnesia brick, clay brick, which type of high temperature refractory brick?
The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
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:What is spalling resistant high alumina brick?
Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.
Q:Which is faster for heat transfer between corundum bricks or high alumina bricks?
There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.
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:What is the difference between T3 refractory bricks or high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
