ABSTRACT:
Process for automatically measuring the shearing resistance of green sand used in a repetitive sand molding process using pattern plates, and for using the measurements in such a way as to modulate the various parameters of the process in which a measuring ring is placed upon one of the pattern plates. The measuring ring has an opening and stress gauges fastened within narrowed sections of said measuring ring on either side of said opening. The gauges are connected electrically through the pattern plate to an electronic measurement and operation device within which various physical measurements are computed, including the shearing resistance of the test sample of sand compressed within said opening. The result of said measurements is processed by a computer to determine the magnitude of modulations to be made, particularly that pertaining to the replenishment of agglomerating agents for the recycled sand.
