Abstract
A ceramic welding process for the formation of a coherent refractory repair mass on a surface of an electrocast refractory material includes providing an electrocast refractory material having a surface to be repaired; providing a first powder mixture comprised of combustible particles, refractory particles, and at least one constituent which enhances production of a vitreous phase in the coherent refractory repair mass; and projecting the first powder mixture in a gas stream containing oxygen against the surface to be repaired so that the combustible particles react with the projected oxygen against the surface in a highly exothermic manner and release sufficient heat of combustion to form a first coherent refractory repair mass.
