- Q: What are the physical properties of refractory material?
- The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
- Q: How to choose refractory material
- Refractory fiber according to different raw materials, there are aluminum silicate, quartz, alumina and graphite, refractory fiber. Commonly used aluminosilicate refractory glass fiber is amorphous, including ordinary aluminum silicate fiber, high-purity aluminum silicate fiber, chromium silicate fiber, long-term use temperature of 1000-1200 degrees.
- Q: How is the performance of refractory materials?
- It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
- Q: What is refractory aggregate?
- It includes two categories: coarse aggregate and fine aggregate.
- Q: Fire resistance and evaluation of refractory for casting
- The refractory degree of refractory material at high temperature is called refractoriness. Refractory products all contain substances from fusible sintering action, the melt crystal as unlike at a fixed temperature, but the temperature in a wide range. At a lower temperature, a small amount of melt is formed, and as the temperature increases, the amount of the melt increases, and the product gradually softens. Refractoriness and melting point (crystal) are different concepts.
- Q: Detailed description of magnesia dolomite refractory material?
- In the cement kiln firing zone, the f-CaO in the dolomite material is easily combined with the C2S in the clinker to form C3S, so the kiln cover can be easily hung, and the kiln crust and the refractory brick are firmly combined and easy to maintain.
- Q: Which brand of refractory fiber hard thermal insulation board is better?
- Thermal insulation materials are divided into two types: porous material and heat reflecting material. The former uses the air void contained in the material to maintain thermal insulation itself for the heat conductivity coefficient of air or inert gas within the voids is low, such as foam material, fibers and other materials; the latter material has a high coefficient of reflection which can reflect the heat, such as gold, silver, nickel, aluminum foil or metallic coated polyester and polyimide thin films. Aerospace industry has strict requirement for the weight and volume of thermal insulation material, and it is often also required to has the properties of noise absorption, vibration attenuation, and anti-corrosion. Different aircrafts have different requirements for thermal insulation materials. Aircraft cabin and cockpit usually use foam, ultra-fine glass wool, high silica cotton to maintain thermal insulation. Earlier missile head uses phenolic foam plastic as thermal insulating material. With the application of polyurethane foam with good thermal endurance, the single insulating material has been developed to sandwich construction. A few millimeters foaming coating is coated on the skin outside the missile instrument bay, it is anti-corrosion coating at room temperature and when aerodynamic heating reach 200 ° C or more, it will generate foam evenly thus maintaining thermal insulation. Artificial earth satellite moves in an environment where the temperature varies from high to low, so it must use laminated thermal insulation material with high reflecting performance, which is usually made up of dozens of layers of aluminum film, aluminized polyester film, and aluminized polyimide film. In addition, the successful development of the surface thermal insulated tiles has solved the problem of thermal insulation of the space shuttle, it also marks a higher level of development of insulation materials.
- Q: Can anyone tell me what is a high alumina refractory?
- High alumina refractories: High-alumina refractory products have high refractoriness, compressive strength and refractoriness under load, which are used for building the high-temperature parts of various large blast furnaces, such steelmaking furnace, airheater, electric furnace, rotary?kiln and other thermal equipment.
- Q: What can red stone refractory do?
- In severe cases, the resistance to high temperature without softening down the Celsius temperature. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output. Chinese use less impurity clay in more than 4000 years ago, firing pottery, and have been able to cast bronze. In the Eastern Han Dynasty (AD 25 ~ 220) have been used to make clay refractory kiln firing porcelain material and sagger. At the beginning of twentieth Century, the development of refractories to high purity, high density and ultra high temperature products, while developing completely without firing, small consumption of unshaped refractory materials and high refractory fiber (160 for industrial furnace refractories above 0 DEG C). The former, such as alumina refractory concrete, is often used in large chemical plants, ammonia synthesis plant, two - stage reformer furnace wall, the effect is good. Since 50s, the rapid development of atomic energy and space technology, the development of new energy technology, requires the use of special refractory material of high temperature resistance, corrosion resistance, thermal shock resistance, erosion has excellent properties, such as melting point above 2000 DEG C, oxide refractory compounds and high temperature composite refractory materials.
