METHOD AND DEVICE FOR CARRYING OUT HOT CASTING OF CERAMIC PRODUCTS FROM SLIP Russian patent published in 1995 - IPC

FIELD: ceramic working; die casting. SUBSTANCE: method involves keeping constant the value of overpressure applied to the slip surface during the time needed to transfer the whole volume of the slip in portions into a tank. To keep the needed overpressure level applied to the slip surface, the space taken by the extruded slit portion is refilled with the corresponding amount of compressed air. Slit temperature is kept constant in the tank and feeding tube. Heated reservoir in the slit tank is provided with a valve mounted in the bottom of the reservoir under the feeding tube and completely covering the area of the tube inlet opening. The heating system and the pipe-line are directly connected with each other. EFFECT: higher quality ceramic products, enhanced accuracy in dosing output quantity of raw materials. 5 cl, 1 dwg
