General Information

The silica brick can be widely used in coke oven, hot blast furnace, glass furnace and carbon furnace. In glass industry, it is mainly employed to build the doghouse crown, suspended wall of channel, top crown and inlet sealing. In metallurgy industry, it is adopted as the nozzle brick

Refractory Acid Reistance Silica Brick For Furnace


Q:The United States of our brick anti-dumping duties?
At present of our brick anti-dumping rate is 73.10%
Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks
Q:Semisilica brick interpretation
High temperature volume stability. Volume change is small.
Q:How much is the highest melting point of silicon?
Acidic silica brick refractories, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature. More than 94% silica content.
Q:Common bond brick?
Manufacturing for silica brick binder hi-li sulfate pulp waste liquid and lime milk. When lime milk is used as a bond, it acts as a plasticizer. To increase the strength of lime brick in the drying process, as mineralizer in the firing, promote the transformation of quartz.
Q:The difference between clay refractory bricks and refractory brick in the application.
Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use, but the anti alkali erosion ability, thermal shock stability is the worst, a scrap. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
Q:Such purpose and scope please give me detailed points thank you because I am learning stage
Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
Q:What is the main material of silica brickIt's common, the kind we see so often!
Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into phosphorus and quartz. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.
Q:The introduction of silica brick
The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass
Q:The high thermal conductivity of silica brick and traditional brick what is the difference?
The scale quartz is a spear shaped double crystal structure, very compact and favorable to the increase of thermal conductivity. The high thermal conductivity of silica brick in improving thermal conductivity and other performance indicators and traditional coke silicabrick agreement.That is to say, the high thermal conductivity of silica brick all inherited the traditional advantages of coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity
