Product Description:

The chrome corundum brick, which is characterized by good mechanical property at high temperature and chemical stability etc., is mainly used as the back lining of the coal water slurry gasifier and petrol coke pressurized gasifier in petrochemical industry, the inner lining of reaction furnace in chemical industry, and high temperature kilns in refractory industry.

So far, it has been applied in the gasifiers imported or China-made in more than 60 plants with good performance. The brick was awarded the Second Prize of Science Progress of Ministry of Chemical Industry. The annul capacity of the chrome corundum bricks is more than 4000 tons.

Q:What does refractory consist of?
Refractory materials can be divided into main raw materials and auxiliary raw materials according to their function in the production process of refractory materials.The main raw material is the main body of refractory. Auxiliary raw materials can be divided into binders and additives. The role of bonding agent is to make the refractory body in the production and use process has enough strength. There are commonly used lignin, phenolic resin, asphalt, cement, water glass, phosphoric acid and phosphate, sulfate, some main raw material itself has the effect of binder, such as clay; additive is to improve the production of refractory materials and construction technology, or strengthen the refractory material of some properties, such as stabilizer, water reducing agent, inhibitor, plasticizer, foaming agent, dispersing agent, bulking agent, antioxidant.
Q:What can zirconium sponge do for those industries?
Uses: aerospace, military, nuclear reactions, atomic energy, and metal superhard materials, the manufacture of bulletproof alloy steel, can also be used in the reactor uranium fuel coating alloy; zirconium at high temperatures easy to launch electronicProduct characteristics: zirconium metal has very strong corrosion resistance, ultra high hardness and strength
Q:High temperature refractory material
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 brick. Acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high that is close to the refractory, the volume does not shrink after repeated burning, or even a slight swelling, but the thermal shock stability. Silica 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 brick for glass furnaces and used for coke oven two kinds of brick 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, wide application Pan, clay brick with refractory clay as main raw material is called ordinary clay brick, made with bauxite clinker as main raw material, the porosity in the clay brick below 17% is called low porosity clay brick. Two kinds of clay brick and according to the physicochemical indexes which were divided into several grades, the price difference between ordinary clay brick and low porosity clay brick greatly.
Q:What are the advantages of refractories?
Basic refractory material generally refers to Magnesium Oxide or Magnesium Oxide and calcium oxide as the main component of refractory materials. This kind of refractory material has higher refractoriness and strong resistance to alkaline slag.
Q:Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
Do not know where the coking plant do dust treatment, processing conditions are different, the dust collector is not the same
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.
Q:Zirconium corundum 25 content and 40 content, how to distinguish in appearance?
The fused zirconia corundum brick is mainly made of fused zirconia and corundum. ZrO2-Al2O3-SiO2 three element system fused brick, containing Al2O3:40% to 50%, ZrO2:30% to 50%, SiO2:10% to 17%.From the point of view of data analysis, there is no radioactive substance in it, and it will not cause harm to the human body.
Q:What is the difference between T3 refractory bricks and high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
Q:Which is faster for heat transfer between corundum bricks and high alumina bricks
For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
Q:What is the hardness of corundum refractory bricks?
Such as zirconium corundum refractory brick, chrome corundum refractory titanium corundum refractory brick.
