PROCESS AND APPARATUS FOR INTERMITTENT SPRAYING OF A PASTE-LIKE COMPOSITION

摘要

Process and apparatus for intermittant spraying of a paste-like composition In a process for intermittant spraying of a paste-like hardening composition mixed with a tempering liquid, especially for the formation of refractory linings in metallurgical vessels, the composition is transported from a place of preparation where the composition is prepared to a delivery nozzle. In order to prevent the composition from incrusting or thickening in the conveying path towards the delivery nozzle during interruption periods of the spraying it is arranged that during said interruption periods the composition is transported in a circular manner, said circle including the delivery nozzle.
