fired materialsbasic high alumina & fire clay products are fired by brice co tunnel kiln to required temperatures of 1750 deg.c.at wistra shutter kilns.
chemically bonded and heat treated materialshigh strength and pyroplastic materials are either cured or heat treated, to appropriate temperatures, thereby allowing the final properties to be developed during service.
magnesite (normal grede glassil mgn)a high quality magnesite bricks is based on a naturally occurring raw material with an inherent high lime/silica ratio and a consistently low iron oxide content which makes a highly suitable for use in electric arc furnace walls and slack linings.
dense & super magnesite (glassil mgd & glassil mgs)a high performance refractory based on specially selected high purity sea water magnesite / fused magnesite. this quality is specially designed for use in basic oxygen furnaces and other arduous operating environment in steel marketing.
