High Strength,High Alumina Castable For Selling

Q: Which manufacturers have the best fire-proof materials with light weight?: Recommend Hubei Boyuejia Industrial Co., Ltd. It is a specialized high-tech enterprise that integrates research and development, production, sale and installation of new lightweight fireproof partition panel, partition panel, new partition panel and mechanical?equipment. Products are lightweight, fireproof, waterproof, sound insulation, thermal insulation, fracture resistance, anti-permeability, environmental protection, strong constitutive property (dense humidity) and other superior performances. It can be widely used in all types of lightweight wall panel of all kinds of buildings, and is one of the preferred materials of plant, residence, hotel, office building and public buildings.

Q: What requirements should refractory materials meet?: Ladle is an necessary equipment to undertake molten steel and continuous casting. As many kinds of steel needs to be processed in the ladle, including argon blowing tempering, alloy composition fine-tuning, refining dusting and vacuum processing, working conditions of the ladle lining have worsened. Their working conditions are as follows. (1) The temperature of molten steel is higher than mold casting ladle. (2) the molten steel stays longerin the ladle. (3) ladle lining are subjected to volatilization and agitation of molten steel under high temperatures and in vacuum. (4) The impact on the lining when undertaking steel liner when the impact effect. Therefore requirements of the ladle refractories are as follows: (1) It can resist high temperature. Molten steel should be able to withstand high temperatures without melting. (2) It can resist thermal shock and can withstand molten steel without cracking and spalling. (3) It can resist slag erosion. The ladle should be able to withstand the erosion of lining caused by slag and alkalinity changes of slag. (4) it should have sufficiently high temperature mechanical strength to withstand the agitation and scouring of molten steel. (5) lined should have certain swelling property so that lining will be united as a whole under the effect of hyperthermal molten steel.

Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.: With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.

Q: How many types do refractory bricks have? Where the quality of refractory material is best? What is the model?: Sinosteel Luoyang (Luoyang Refractory Material Plant in the past): High alumina(mainly blast furnace), Gongyi. There are also a series of high-tech materials (silicon carbide, carborundum, etc.) a major producer of high alumina; silicious: Resistant material for steel, glass furnace, cement kiln); magnesia. Divide from uses and divide from chemical texture; silicious(glass furnace): Xinmi, Hennan Province, Lengshui River, coke oven, etc.). As for the models, Yixing and Changxing in Jiangsu Province: Haicheng, Liaoning Province; silicious, I do not understand your intentions; magnesia (nonferrous, steel refining; magnesia: High alumina brick; Dashiqiao area! Please put it in detail.

Q: Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.: Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.

Q: Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?: Add some hair and slags, or it will crack before calcination.

Q: how is the high-temperature flame-retardant fibre board?: Temperature refractory fiberboard is of high quality and not likely to be damaged. It is light and easy to install.

Q: What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?: Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Boric acid is used according to the type of steel, the specific ratio is too generalized, and it shall be determined when the type of steel is detailed.

Q: Which one is better, fire-resistant wood or steel?: From the aspect of low-carbon and environment protection, the steel and timber structures are both OK, they are both renewable resources, the steel can be recycled and melt down again and wood can continue to be planted. Fireproof board Fireproof board is a refractory material used for surface decoration. It is widely used in interior decoration, furniture, kitchen cabinets, laboratory tables, walls, and other fields.

Q: What is the the best ratio of mortar in refractory cement?: The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
