Abstract
A refractory block assembly for the nose ring of a rotary kiln. Self-aligning nuts contained in recesses of a refractory casting generally align with bolts radially extending through holes spaced around the periphery of a retainer in the nose ring. The nuts and recesses are sized and configured to permit limited lateral and rotational displacement of the nut for threadingly engaging the bolts.
