General Information

Ceramic firing kiln refractory Silica Brick Description:

Refractory Silica Brick is mainly made of top class silica, via shaping and burning under the high temperature,

Possesses high temperature resistant, high strength and low impurities, etc.

It is mainly used for blast furnaces and hot blast stove.

Features

Ceramic firing kiln refractory Silica Brick Advantage:

1) Silicon oxide is above 95%.

2) Good acid erosion resistance.

3) High softening point

Applications:

Light weight silica bricks are primarily used for furnaces and kilns in metallurgy, steel, power, chemical industry, and electric power and machine building etc areas

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: Physical solid waste disposal: Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.

Q: The hot blast stove when the temperature did not rise against the brick interface decreased: Insulation of hot blast stove, key insulation silica brick hot stove, hot blast stove is shutdown or need repairing in blast furnace.

Q: The specific content is what gb/t2608-2012 brick: Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.

Q: The difference between clay refractory bricks and refractory brick in the application.: The ability of alkali resistance is poor, the thermal shock stability is the worst, and it is scrapped at one time. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.

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 United States of our brick anti-dumping duties?: . According to the relevant legal procedures, the United States International Trade Commission will make a final ruling on the anti dumping industrial injury before January 6, 2014, if an affirmative determination, the U.S. Department of Commerce will be involved in product release tax anti-dumping order.

Q: Can iron oxide be used as refractory material?: Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment

Q: Brick: An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance. 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 quartz in the body. 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.
