Refractory composite.Zircar Refractory refractory Material that is not deformed or damaged by high temperatures, used to make crucibles, incinerators, insulation, and furnaces, particularly metallurgical furnaces. Composites Inc. unveiled its new refractory sheet type RSLE-57. The low" expansion, high-strength reinforced silica matrix composite was designed for use as an insulator insulator Substance that blocks or retards the flow of electric current or heat. An insulator is a poor conductor because it has a high resistance to such flow. Electrical insulators are commonly used to hold conductors in place, separating them from one another and from in induction hot press applications. The material's low thermal expansion thermal expansion Increase in volume of a material as its temperature is increased, usually expressed as a fractional change in dimensions per unit temperature change. coefficient and high hot strength combine to give it high thermal shock Thermal shock in mechanical models Thermal shock is the name given to cracking as a result of rapid temperature change. Glass and ceramic objects are particularly vulnerable to this form of failure, due to their low toughness, low thermal conductivity, and high resistance. The composite is 100% organic free and contains no refractory ceramic fiber.--Zircar Refractory Composites Select No. 124 at www.moderncasting.com/info [ILLUSTRATION OMITTED] |
