Abstract: A slide gate nozzle for a slide gate carried by a closure frame which includes two independent arms pivotally connected with a casting vessel for slidably moving the slide gate with respect to the casting vessel and for moving the slide gate away from the vessel to facilitate changing of the ceramic plates. Rocker frames are pivotally connected with the arms and include rollers on which a guide rail rides in the sliding direction of the slide gate, and the swivelly connected rocker frame assures even pressure of the ceramic plates.

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.
