Specifications

Light Weight Silica Insulation Brick For Blast Furnaces;
Good quality and low price;
With 25 years experience

Light Weight Silica Insulation Brick Description:

It 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.

Light weight silica brick Advantage:

1) Silicon oxide is above 95%.

2) Good acid erosion resistance.

3) High softening point

Light Weight Silica Insulation Brick 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

Light Weight Silica Insulation Brick

Q: Semisilica brick, clay brick, high alumina brick and what is the difference?: The share of A12O3 and SiO2 is different

Q: Which material is good for furnace refractory?: Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 94% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, thermal shock resistance is poor. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used.

Q: The brick is mainly used in the place?: Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.

Q: The United States of our brick anti-dumping duties?: At present of our brick anti-dumping rate is 73.10%

Q: What are the main constituents of refractory bricks?: Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:

Q: Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450: That is because the brick load softening point the maximum temperature is 1450 degrees.

Q: The chemical composition of silica brick and its physicochemical index?: The physicochemical index of silica brick:Turn left to |

Q: What is the silica refractory products?: Refractory brick with silica content greater than 90%.

Q: Physical solid waste disposal: 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: The formula in the refractory brick, and firing curve, who knows?: Add 1.8-2.2% of the total weight of the main raw material, and then add lime milk, rolling for 10-15 minutes, and finally add pulp, rolling for 10-15 minutes, out of the mill, forming billet.
