- 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 is the blast furnace ceramic cup called by the refractory factory?
- In fact, a kind of ceramic cup of blast furnace refractories, application in blast furnace bottom and hearth contact steel lining using a layer of non carbon refractory materials, such as Theron with corundum brick, corundum mullite and synthetic mullite bricks etc..
- 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?
- Do not know where the coking plant do dust treatment, processing conditions are different, the dust collector is not the same
- 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's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
- The fused zirconia corundum brick is made up of 30% ~ 41% zirconia two in the alumina burden. The main mineral compositions are corundum, zircon and glass phase. The main varieties are fused (or cast) zirconium corundum brick (also known as AZS casting brick) and sintered zirconia corundum brick. Generally speaking, zircon corundum brick means sintered zirconia corundum brick. It is made from alpha -Al2O3, partially stabilized zirconia and zircon corundum clinker, which is prepared by proportioning and molding at 1700~1750 DEG C and then sintered at two. The sintered zirconium corundum brick has a strong resistance to molten glass, and its thermal shock resistance is stronger than that of fused zirconia corundum brick. It is mainly used as lining of glass furnace and induction furnace, as well as steel rolling furnace, slide rail, etc..
- Q: How do corundum bricks bind?
- High temperature bonding clay can be used for bonding masonry
- Q: What kind of refractory material will be used in the glass kiln?
- High temperature & glass corrosion performance of the brick is slightly lower than that of chromium oxide, also by isostatic pressing forming method, its technical indicators ZrO2>65%, <2.0% porosity, volume density of about 4.25g/cm3, the temperature in E glass is higher than 1370 DEG C have erosion. Used in the E glass melting pool unit kiln glass temperature slightly lower at the end of the transition path, forming the bottom of the pool and forming path path flow tank and bushing support brick etc.. In addition, the dense zirconia brick is used as the backing brick of the dense chrome brick.
- Q: What are the refractory materials?
- Neutral refractory is mainly composed of alumina, chromium oxide or carbon. Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick by using chromium oxide as the main component of the corrosion resistance of steel slag is good, but the poor heat shock resistance, high load low deformation temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, heat vibration performance, high strength, corrosion resistance to acid and salt, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry.
- Q: What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
- The expansion curves of fused cast AZS brick at 1000 DEG C near a crystal anomaly, its internal changes of ZrO2 crystal are reversible, with large volume change, therefore, products containing ZrO2, should not be used in the temperature of 1000 DEG C, often have sharp fluctuations in the position. When baking the kiln, the temperature can not be too large at 900~1150 degrees centigrade. Generally, the temperature can not exceed 15 degrees /h, and the temperature should be raised steadily. Some parts to prevent the cold, with other brick protection, to prevent explosion.
