Claims9
In a process for repairing hot refractory linings by applying a refractory composition by spraying onto the site to be repaired, the improvement comprising applying a composition containing combustible elongated channel-forming elements substantially evenly distributed throughout the composition
- wherein the hot refractory has a temperature greater than that at which the channel-forming elements are combustible.
In a process for repairing refractory linings having a temperature of 1400.degree. C. by applying a refractory composition by spraying onto the site to be repaired, the improvement comprising applying a composition containing combustible, elongated channel-forming elements substantially evenly distributed throughout the composition, said composition being based on a refractory mass of Al.sub.2 O.sub.3 and having minor amounts of binders, said elements being palm tree fibers having a length of 1 to 3 centimeters and constituting 0.2% by weight of the composition.
