- 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: 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 are the advantages of refractories?
- Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials. For example, AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on
- Q: What refractory materials are used in industrial furnaces?
- Masonry parts using his cooperation because of the repair or overhaul time, labor, materials, fuel consumption is great. Some of the other, a stove overhaul, will inevitably affect the other parts of life. Therefore, the selection of materials should be thinking of various parts of masonry of life, the habit.
- 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 refractory materials are adopted in each part of the blast furnace?
- The lower part of the shaft due to high temperature and dust by scouring and alkali metal vapor erosion, so the requirements for the slag resistance, alkali resistance and high temperature resistance, wear resistance of high quality clay brick, high alumina brick, carborundum brick or corundum brick. Belly temperature reaches 1400~1600, and slag, steam erosion, erosion and corrosion is strong, therefore, the silicon carbide reaction bonded silicon carbide brick.
- Q: What is the hardness of corundum refractory bricks?
- Al2O3 containing more than 90% greater than the refractory brick called corundum refractory brick, also known as pure alumina refractory products. Corundum has a high hardness (9 Mohs hardness) and a high melting point. These are closely related to the firmness of the Al - 0 bond in the structure. Therefore, a-Al2O3 is the main phase of making high temperature refractory bricks and high temperature electrical insulating materials.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
- Q: What are the main constituents of refractory bricks?
- Clay brick and clay brick are mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and square quartz and quartz (up to 30%). Usually with hard clay as raw material, pre calcined mature material, and then with soft clay, semi dry or plastic molding, the temperature at 1300~1400 C fired clay brick products. Can also be added a small amount of water, glass, cement and other binders to make non burning products and amorphous materials. It is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.
- Q: What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
- Cast brick and clay brick masonry contact, eutectic phenomenon will occur at 1300 degrees Celsius, the selection of refractory materials, should avoid eutectic phenomenon serious two kinds of refractory materials such as brick masonry contact, in the following cast brick, the most vulnerable to erosion fused zirconium corundum brick.
