Аннотация: The advantages of the AlpHaset process, the features of its application, the requirements for the materials used are considered. Molding sands, making in Russia are analyzed. It is noted that the consumption of molding and core mixture used in the manufacture of castings using this process is reduced by 3-4 times. The mixture after knocking out is regenerated up to 90%, which, in comparison with liquid glass, does not require the removal of spent molding and core mixtures to the dump, thereby, improving the environmental situation in the industrial zone. In addition, this process contributes to the introduction of environmentally friendly technological process of manufacturing castings in foundries of machine-building enterprises and individual foundries. The best values of strength are achieved on quartz sand, with a content of fine dust particles ranging in size from 0 to 0.125 mm less than 2% and a residue on the grid of 0.125 mm maximum 5%. The average grain size of such sand should be 0.25-0.30 mm. The molding sands produced in Russia are analyzed. The conclusion is made on the application of the AlpHaset process, based on the use of molding sand, produced according to Russian State Standard 2138-91. © 2020 Trans Tech Publications Ltd, Switzerland.
