Thermal insulating refractory material ZIRCAL-A

calcium silicaterodasbestos-free

ZIRCAR Refractory Composites Inc., provides a variety of non-asbestos calcium silicate structural insulations that combine high strength and excellent thermal insulating characteristics for use in a variety of heat processing, fire protection and electrical resistance applications. The unique calcium silicate structure provides excellent thermal shock resistance as evidenced in its typical use as a direct contact board for non-ferrous metals and in fire training burn rooms. They are fire resistant to temperatures approaching 1100°C(2012°F). They also exhibit low thermal conductivities that remain relatively constant over a broad range of operating temperatures. ZIRCAL-A is a strong, machinable, non-asbestos and inorganic board insulation ideal for conveying, containing, handling and forming molten aluminum and other non- ferrous metals. ZIRCAL-A can be used in aluminum contact applications up to approximately 816°C (1500°F). Made of fibers, micro silica and a hydro thermally produced inorganic binder, and are ideal materials for conveying and controlling the flow of aluminum. They are manufactured for greater life and improved machining characteristics. In addition, high heat treatment removes excess water, and minimizes shrinkage that would normally occur in service. This unique material has many outstanding advantages. Most Non-Ferrous metals do not adhere to it, even when they cool and solidify, so skull can be easily removed. It will require no foundry facing wash, and does not lead to contamination of the metals. Molten metals are conveyed with less heat loss, so stay at a more uniform temperature, and therefore can be handled at a lower temperature.
