Document Type and Number:
Japanese Patent JPS6032927
Kind Code:
Y2
Abstract:
A process for controlling a vessel for a repeated pouring of a liquid under low pressure into blind sand moulds. The process comprises after each pouring, lowering the liquid in the pouring tube only to a level which is equal to or substantially equal to a constant predetermined level in the vicinity of the outlet of the tube. According to the invention, the level of the liquid in the tube and the pressure of the driving gas prevailing in the vessel are measured directly and the inlet and exhaust of the driving gas are controlled as a function of these measurements so as to ensure, for all the pourings, a pressure rise time and a pressure drop time which are predetermined and substantially constant. A device is described for carrying out this process.
