Abstract
An enclosure designed to maintain the purity and physical characteristics of a slurry within a preferred range during the manufacture of shell molds is disclosed. The tank is in the form of a trough with flat side walls and a curved member forming the front, bottom and back of the trough. The entire trough is water cooled and a cover along the top completes the enclosure. The enclosure is fitted with means for circulating the slurry and a liner having an airfoil member. Various sensing and control means are interconnected through a feedback system which continuously monitors and controls the conditions of the slurry.
