The technology center is testing capabilities include: construction of the plate, siliceous refractory products, clay refractory products, high alumina refractory products, specialty refractory products, insulating refractory products, refractory materials, unshaped refractories (Refractory material) and other physical and chemical Performance analysis and detection. Major equipment: 721 spectrophotometer, flame photometer, pressure testing machine, automatic temperature under load test machine, automatic load soft creep testing machines, automatic high-temperature thermal expansion instrument, flat thermal analyzer, automatic temperature flexural testing machine, thermal shock resistance test furnace, refractoriness test furnace, electric bending, high temperature reheating furnace experiments at room temperature wear resistant test furnace, rotary furnace slag resistance test, apparent porosity, density tester and other large body detection equipment . Because calcium silicate insulation material has not been wet nonferrous metals melt performance, therefore, suitable for use as the preservation and transport of molten nonferrous insulation materials, can also be assembled with calcium silicate material melting tank lining refractories, chute or cover. Due to the small amount of hot melt materials and calcium silicate refractories lowest good insulation properties, which can reduce the melting temperature of the casting process and ensure the normal. When magnesia contact with molten metal, crystal water decomposition magnesia refractories where to buy the metal inside the bubbles. Therefore, when using the article of refractories containing magnesia Which good, should be pre-heating treatment, in order to exclude moisture. When no magnesium calcium silicate alone is not necessary to pre-burn treatment products, which is one of its advantages.
