For nearly one full Man-Century, ZIRCAR Ceramics has been manufacturing Ceramic Fiber based materials that have helped enable the advancement of some of the finest technologies on the planet - including but not limited to advances in specialty glasses, light metals, powder metals, semiconductor crystals and many more. Significant advances have been facilitated by the extensive range of standard [...]
Manufacturing Ceramic Fiber Insulated Heaters (FIH) is not Rocket Science but it does require appropriate capital equipment, design engineering, tool fabrication and manufacturing resources. Large FIHs can require several hours of preparation wherein helically wound coils of resistance wire are precisely positioned on the mold (as shown above) prior to vacuum forming. The largest FIHs ZIRCAR Ceramics has [...]
General Information ZIRCAR Ceramics’ RNKO-HD Alumina-Silica board is a uniquely strong, low-density combination of 1260oC rated Al2O3-SiO2 (RCF) fibers and a stabilized inorganic amorphous SiO2 binder. RNKO-HD is 100% organic free. At 0.85 g/cc (53 pcf) density, RNKO-HD has been developed for applications where a combination of low thermal conductivity and the abilty to withstand high compressive loads at [...]
The answer is Alumina Rigidizer Type AL-R/H. Alumina Textile Type AS-7M is an incredible material. It retains 100% of its tensile strength when exposed to temperatures as high as 1200C. Type 0909-P is commonly used as a reinforcement in advanced refractory structures including CMCs. Because AS-7M is manufactured with only a minute amount of organic sizing added in the yarn [...]
ZIRCAR Ceramics has been manufacturing castertips and other ceramic fiber based products for use in continuous aluminum sheet casting for many years. Today, our customers find significant value in our casthouse consumables including: Castertips, Troughs, Rigid and flexible launders, Tundishes, Colloidal Graphite Release agent, Boron Nitride non-wetting coating, Tabular Alumina balls and gravel and CNC refractory hardboard products. Helping you [...]
In many applications to 1200C, ZIRCAR Ceramics’ Alumina Silica Type AXL is a self-supporting high temperature thermal insulation capable of spanning fairly large distances. The 1.5” thick half-Octagon sheets are used in a large crystal growing process. Complete information about AXL can be found on our website using this link. https://www.zircarceramics.com/product/axl/
End dams used on Continuous Aluminum Sheet Casters ( Twin Roll Casters) are manufactured from a wide variety of materials. Which type of end dam is used depends upon certain operating requirements. For soft alloys cast in 0.25" thickness ZIRCAR Ceramics' ECO-27 is a cost effective material to use. CNC machined then hardened, ECO-27 helps many customers make better metal.
ZIRCAR Ceramics is now offering custom fabricated flexible launders for use on Molten Aluminum transfer applications. Constructed of Alumina Textile Type AS-7M cloth as the metal contact surface with a filler of low density blanket insulation backed by a high strength fiberglass outer cladding, ZIRCAR Ceramics’s Flexible Launders can be coated with Boron Nitride or other refractory coatings and can [...]
ZIRCAR Ceramics owns and operates nearly 2 dozen kilns. Several are small top loading kilns that are fired to 1300C. By replacing the original IFB lined lids with a stacked blanket (ZIRCAR’s Alumina Type NMB) we have extended the life of the lid significantly, made the kiln more energy efficient and with the simple lift system, made it much easier [...]
