Abstract

Studies have been carried out on the choice of compositions of molding sands for especially critical parts of the rolling stock. Quantitative statistical dependences in the formulation of mixtures have been obtained. dependences of gas permeability, work, cost for destruction and rigidity of the sample on the magnitude of various loads.
