Abstract
A refractory panel is formed with recesses delineating a pair of adjoining brick relief patterns. One or more depressions are formed in the recesses such that grout or the like placed in the recesses form fingers that harden into position.
Claims68
A refractory panel, comprising:
- a refractory panel formed of a refractory composition, where the refractory composition comprises:
- first and second raised portions;
- a recess defined by the refectory composition separating the first and second raised portions, the recess having a first length, and the recess extending part way through the refractory composition, and
- one or more depressions having a second length, the one or more depressions extending from the recess into the refractory composition, the recess being configured to receive a material that is capable of working into the one or more depressions prior to hardening,
- wherein the second length is shorter than the first length.
