Abstract
An apparatus for the applying of refractory material in 360 degrees while the apparatus is raised or lowered vertically or inserted and retracted horizontally can apply a layer of material continuously on the interior surface of a hot vessel. Wet mixed refractory material is supplied to an applicator and pressurized air is supplied to the applicator so as to rotate a spinner head on the applicator. The apparatus includes a shroud around the housing of the applicator which conveys the pressurized air around the housing to cool the housing below the temperature of the vessel. Also described is a method of applying refractory material by a spinner head on the applicator in the form of a spray to hot metallurgical vessels such as the snorkel tubes of vacuum degassers and ladles.
