Abstract
A method of providing on a surface of a furnace a refractory covering including the steps of affixing to the surface of the furnace a fiber blanket layer formed such as mineral wool, fiber glass and ceramic fibers and then spraying on the blanket layer either pneumatically or hydraulically, a castable refractory, the fiber blanket absorbing the kinetic energy of the castable refractory causing an increased proportion of the sprayed material to adhere thereto, and permitting the refractory to harden into a continuous refractory covering.
