Features of our Insulating Firebrick are Excellent strength at ambient and elevated temperaturesHigh compressive strengthEvery brick ground to precise dimensionsVery low levels of iron and other impurities (especially resistant to tough, reducing atmosphere conditions)Lightweight, energy-saving nature results in less heat loss, lowers operating costs, and allows for thinner furnace liningsLower heat storage than denser refractoriesHeats quickly and economically to kiln's operating temperatureCools fast to speed periodic operationsAvailable in custom designed shapes upon request Kiln is the heart of any ceramic process, and hence the proper functioning of the equipment is of prime importance. Over the years, there has been a steady increase in technical demands in terms of shorter cycle times, homogeneity of temperature and regulation of atmosphere in the kiln for improvement in product throughput and quality and increased fuel efficiency. Refractories play a major part in satisfying the above criteria; hence, in order to cope with ever growing demands of the market, CUMILAG 26, which can withstand temperatures up to 1400A A C, is extremely light and porous and has excellent thermal insulating properties. It is normally recommended as back up lining in kilns. CUMILAG 29, which is a hot face insulating refractory of high purity, is designed for prolonged and has service at 1450A A C and intermittent operation at a service temperature of 1500A A C. The uniqueness of this refractory is its uniform pore structure, that makes it an ideal material for high temperature applications. It can be cut to any desired shapes.
