Why high-density calcium silicate insulation products will have a better market in the future?


High density calcium silicate insulation board is a kind of calcium silicate board with a density of 800-1000kg/m3 specially developed for non-ferrous metals, which uses Japanese technology, the use of calcium oxide is silicon dioxide through static reaction and then add some stable materials, the structure is a ruse crystal system, the use of calcium silicate temperature 1000 degrees, can fully achieve the use of casting aluminum environment. The product has a low coefficient of thermal expansion of 850 degrees for 3 hours < 0.3%, and has excellent thermal shock resistance. In addition, it has the characteristics of non-wetting with many metal (especially non-ferrous metal) melts and glass melts. Therefore, it can be used for the conveying, shipping, molding of molten aluminum, and can also be used for the glass industry. In addition to its own insulation, its non-stick aluminum characteristics have been greatly played, high strength, good processing performance, CNC machine tools can be used to process accurate size products and complex components. There are two types, glass fiber reinforced and carbon fiber reinforced, which are more widely used: ladle heat shield, automotive glass birthgear, dropper, flow tube, hot top ring, brake pin, ear, float, flow groove. The application fields are also broader: petroleum, chemical, building materials, light industry, machinery, metallurgy, electric power, aluminum and other industries.

Taking high-density calcium silicate ceramic gate sleeve/thermal insulation cap as an example, its corrosion resistance, strong thermal insulation and high temperature resistance are stable, effectively ensuring the temperature of the feeding channel, and the cooling strength of other parts of the casting will not affect the feeding of the casting, and the production efficiency will be significantly improved, and the casting quality will be significantly improved. And the final solidification of the riser part of the waste weight is only the traditional metal materials in general. During low pressure die casting, the aluminum liquid in the holding furnace of the die casting machine enters the mold cavity through the riser pipe through the gate sleeve of the pouring cup under the pressure, and the cooling system completes the sequence solidification under the pressure, so the gate part also plays the role of riser. In the process of low-pressure casting of aluminum alloy wheels, the pouring system is particularly important, which not only makes the liquid aluminum fill the mold cavity smoothly, but also plays the role of feeding in the blank solidification stage to obtain the casting with dense internal organization.

The gate cover is located at the junction of the pouring system and the forming system. The gate cover is an important part of the aluminum alloy wheel die-casting system, like a bottleneck, which can be called the throat of the die-casting system. Its structural design and material selection have an important influence on the filling and solidification of the profile,So the market will have a broader prospect in the future.
