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 600°C(1112°F) to 1650°C(3002°F). 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 Vacuum Degassers Product: Refractory Sheet Type RS-A Moldable Application Information: In this application, Refractory Sheet Type RS-A Moldable acts as a gasketing material sections of tubes used in vacuum degassing of molten steel. Inert gases are bubbled through the molten steel to impart purity. Type RS-A Moldable replaces a cast refractory material which cracks and breaks down at higher temperatures. Therefore, with the use of RS-A Moldable, there is less occurance of downtime needed to overhaul the degassing units. Benefits: The benefits of using RS-A Moldable in this application are: RS-A Moldable withstands high temperatures up to 1450°C(2642°F), its high alumina content reduces the occurance of imperfections in the molten steel due to contaminants such as when products containing silica are used; RS-A Moldable is flexible, it fits easily into the contours of the vacuum degasser, at 260°C(500°F) RS-A Moldable bakes out to a rigid material fitting the shapes needed; with the addition of AL-HARD, a phosphate bond occurs which makes the RS-A Moladble more rigid and structurally sound.
