A method for preparing a metal reinforced refractory body comprising the steps of providing a mold for containing a slurry of refractory material. A body of metal fibers is inserted into the mold, the metal fibers having a coefficient of thermal expansion of less than 10×10−6 in/in/° F. and a yield strength of greater than 35 KSI at 1200° F. The slurry of refractory material is introduced to the mold to provide the slurry in intimate contact with the metal fibers, the refractory material in the hardened condition having a coefficient of thermal expansion of less than 10×10−6 in/in/° F. The refractory material is hardened to provide a metal reinforced composite refractory body comprised of a reinforcing component and a refractory component having a coefficient of thermal expansion of less than 10×10−6 in/in/° F. to minimize cracking of the refractory body.
A method for preparing a metal reinforced refractory body resistant to cracking at elevated temperatures comprising the steps of:
A metal reinforced refractory body comprised of a metal component having a coefficient of thermal expansion of less than 10×10−6 in/in/° F. and having a yield strength of greater than 35 KSI at 1200° F. and a refractory component having a coefficient of thermal expansion of less than 10×10−6 in/in/° F., the body being highly resistant to cracking at elevated temperatures.
