ZIRCAR Refractory Composites, Inc. produces a comprehensive line of advanced high performance ceramic-ceramic composite materials and related products. Our materials are used around the world in the most demanding thermal, structural and electrical insulating applications ranging in temperatures from 600C(1112F) to 1650C(3002F). For over twenty-five years, we have been a problem-solver working with our customers to resolve their thermal management problems. We have developed products that have become industry standards for induction melting, forging and heat treating applications, investment casting, glass processing, hot pressing, as well as many high temperature electrical applications.

Application Sheet


Application: Gasketing Material Used in Centrifugal Casting of Metals

Product: Refractory Sheet Type RS-DA

Application Information: In this application, Refractory Sheet Type RS-DA acts as a gasketing material in the forming of ferrous and non-ferrous metal solid cylinders. RS-DA replaces cast refractory materials which crack or chip off due to the centrifugal forces of the process and cause imperfections in the molten metal. RS-DA offers a smooth surface and reduces the need to "crop end" the metal cylinders.

Benefits: The benefits of using RS-DA in this application are: the temperature strength of RS-DA is superb, it will not crack at the service temperature of 1371C(2500F), and therefore downtime needed to replace gasketing material is greatly reduced;

RS-DA is not dense therefore the porosity gives better thermal insulating properties than dense castables; RS-DA is more flexible than cast refractory materials and does not break down at the service temperature.
