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: Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.

Q: Physical solid waste disposal: Reduce crack production and improve yield. The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem

Q: What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you: The main damage of silicon carbide side wall brick is stress damage, not chemical erosion. Chemical damage is formed prior to the formation of the groove, and the damage to the chemical erosion is little after the formation of the groove.

Q: Why is the new trend of the high thermal conductivity of silica brick: The high thermal conductivity of silica brick all inherits the advantages of traditional coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity.

Q: Which material is good for furnace refractory?: Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.

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: 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

Q: The chemical composition of silica brick and its physicochemical index?: ????Al2O3 SiO2??????fe2o3??????cao???????r2o93～98?0.5～2.5?；；?0.3～2.5??0.2～2.7；??1～1.5；

Q: The difference between clay refractory bricks and refractory brick in the application.: Clay brick features good thermal shock resistance and low price, but high temperature performance is not well integrated, and the long-term use temperature is not higher than 1300 degrees. It is widely used in low temperature parts of various kilns.
