ВЛИЯНИЕ ПАРАМЕТРОВ ИМПУЛЬСНОГО ПРОЦЕССА НА КАЧЕСТВО ФОРМЫ И ОТЛИВОК

The article examines the impact of parameters of impulse process on the quality of form and the castings. The results of study of the pressure effect over a mixture on the form durability and pressure on the model surface are given. A mathematical yield surface for the form durability depend- ing on hermetic criterion of model-flask accessory and pressure in the receiver in estimating the form parameters without an additional experimental investigation is constructed.
