Abstract
A process for the production of a refractory lining within a tubular vessel which comprises disposing said tubular vessel so that the longitudinal axis running therethrough is horizontal, slinging a moist refractory mass onto a longitudinal or annular section of the interior wall of the tubular vessel and thereafter applying moist refractory mass to additional longitudinal or annular sections as the case may be. The process can be conducted either by rotating the vessel so as to expose successive annular sections and applying refractory mass to said sections from a fixed position or it can be performed by moving the source of refractory mass longitudinally to cover longitudinal sections and rotating the vessel only partially so as to bring the stream of refractory mass against a second longitudinal section. Devices to carry out these processes are disclosed including a slinger machine disposed for longitudinal movement within the vessel and means for rotating the vessel to the desired extent. Reciprocatingly movable supply means for supplying refractory mass to the slinger machine are also provided.
