$Fireclay Brick for Coke Oven Refractory$

Alumina content more than 90%, is given priority to with corundum crystal phase of refractory products.

High room temperature compressive strength (up to 340 mpa).High rul start temperature (greater than 1700 ℃).

Good chemical stability, acid or alkaline slag, metal and glass, etc. Have strong ability of resist.Thermal shock stability is related

to its organizational structure, the erosion resistance of dense products is good, but poor thermal shock resistance.

Divided into sintered corundum brick and fused corundum brick two kinds.Respectively using sintering alumina and fused

corundum as raw materials or Al2O3 / SiO2 than high bauxite clinker and sintered alumina, made by sintering process.

Also can use phosphoric acid or other adhesives made don't burn corundum brick.It is mainly used for blast furnace and

blast furnace hot blast stove, furnace refining furnace, sliding water apparatus, glass furnace, and petrochemical industrial furnaces, etc.

Q: Application of electric high temperature regulating valve?: Acid refractory with silicon oxide (SiO2) as the main ingredient, commonly used are silica brick and clay. Brick is siliceous products containing more than 93% SiO2, the use of raw materials with silica, silica and other waste. The silica acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high, close to the fire, the volume does not shrink after repeated burning, or even a slight swelling, but the thermal shock stability. The brick is mainly used for thermal equipment of coke oven, glass furnace, furnace and other acidic silica brick, according to the physicochemical indexes and SiO2 content can be divided into several levels, mainly used in glass furnace and coke oven silica brick for two categories. Clay brick with refractory clay or bauxite clinker as main raw material, containing 30% to 46% of alumina, refractory degrees 1580 to 1770 DEG C, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used in refractory clay brick clay as main raw material is called common clay brick that made pyrojewel clinker as the main raw material, the porosity in the clay brick below 17% is called low porosity clay brick. Two kinds of clay bricks are divided into several grades according to the physical and chemical indexes. The price difference between the ordinary clay bricks and the low porosity clay bricks is great.

Q: What is the main component of corundum?: Corundum is mainly used in advanced grinding materials, watches and precision mechanical bearing materials. A ruby based artificial crystal used as a laser emitting material. Ruby and sapphire are corundum minerals. Except for the starlight effect, only translucent transparent and vivid corundum can be used as gems. The red is called ruby, while the other tones of corundum are commercially referred to as sapphires.

Q: What is the price of concrete self insulation bricks?: If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)

Q: What is the blast furnace ceramic cup called by the refractory factory?: The peak of new materials in various coal, metallurgy, mines, ports, electricity, building materials and military industry, a lot of workpiece and affect production equipment due to wear, wear resistant materials although rarely cause disasters metal workpiece disaster, but the resulting economic loss is immeasurable.

Q: Which is good, glazed brick and whole cast glazed brick?: Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.

Q: Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?: The sinter plate dust collector is also called plastic plate dust collector. The utility model has the advantages that the utility model can adapt to various complicated working conditions, the dust removal rate is 99.99%, the utility model has the advantages of long service life, stable operation, high temperature resistance, and the utility model is a leading dedusting equipment in china.

Q: What is the difference between corundum and high alumina?: The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.

Q: Is liquid phosphoric acid two aluminum hydrogen flammable?: Liquid phosphoric acid two hydrogen aluminum features: easy mixing, molding, especially suitable for field construction, so liquid phosphoric acid two hydrogen aluminum is not flammable

Q: How do corundum bricks bind?: High temperature bonding clay can be used for bonding masonry

Q: Ask for help about the phase of refractory material: Major crystalline phase. The main crystalline phase is a crystalline phase that constitutes the principal part of the material structure and has a high melting point and a dominant role in the properties of the material. The properties, quantities, distribution and bonding state of the main crystalline phases of refractory determine the properties of the products directly. A lot of refractory products, such as mullite brick, corundum brick, magnesia brick, magnesia spinel brick, silicon carbide refractory products, etc., are the main phase named.
