FIELD: mechanical engineering.
SUBSTANCE: method is proposed for manufacturing blanks of seamless cylindrical solid fuel gas generator housings using a hollow centrifugal cast blank with a 1 mm thick parting paint on the inner surface of the mold with a rotational speed providing centrifugal pressure on the crystallizing metal layer of at least 0.5 MPa, and after extraction of the solidified casting, it is sent without mechanical processing for further broaching and calibration into a four-die forging block to obtain a long tube billet, a multiple for the manufacture of four to six of the aforementioned housing blanks.
EFFECT: ensuring the necessary strength characteristics of the metal.
