- 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 material is used in an iron smelting furnace?
- Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on.
- 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: Wave tile and throwing glaze, tile which good?
- The main advantages of all glazed glazed tiles are that they can be very rich and beautiful in texture and pattern, and they are suitable for family decoration, and can choose patterns according to their own family decoration style. Compared to the glazed tile, it has better pollutant discharge performance, and many pollutants are difficult to penetrate into it.
- Q: Expansion ratio of lightweight corundum refractory bricks
- Now with the production of lightweight foam corundum brick, basically still meters with molding casting, moulding after together with die in the drying room drying in 60~70 C 4 days of release, then the appropriate drying, finally after 1300 and 1550 C firing, the total burning time: 50~60h. Light corundum brick after firing is usually not the size and shape of accurate, so that products after the kiln to mechanical or manual cutting, can be made into a density of 0.8 - 1.3g/cm3, 4MPa compressive strength and porosity, the thermal conductivity of 70%~80% 0.17W/ (M - K), light-weight corundum brick use temperature of 1500~1700 DEG C.
- 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 is the standard classification of high alumina bricks and high alumina bricks?
- Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.
- 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: What are the refractory materials?
- Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.
- Q: What kind of rock is corundum produced?
- Aluminum oxide (Al2O3) mineral. Due to Mohs hardness of up to 9, mainly used as high-grade abrasives. The crystal belongs to the three party system, a dolioform six square column, some are needle or plate. Aggregates are massive or columnar. Usually white, gray, yellow and other colors. If a small amount of Cr3+ is red, a ruby is called;
