LAWS GOVERNING THE FABRICATION OF CASTING BLENDS AND CASTING MOLDS PRODUCED FROM MATERIALS BASED ON THE SYSTEM GYPSUM - METAL PHOSPHATE SOLUTION FOR NON-FERROUS CASTING

摘要

A mechanism that produces the effect of metal phosphate solutions on the rate of solidification of plaster blends is proposed on the basis of theoretical and experimental investigations. Optimal parameters for treatment of metal phosphate tempering agents by means of nonsinusoidal electromagnetic pulses are established and determined. A highly efficient technology for the fabrication of plaster molds for art casting from wax patterns is developed.
