METHOD FOR MAKING FUNNELS OF CUMULATIVE CHARGES

摘要

A method for making funnels of cumulative charges includes setting and volumetric deformation of copper ingot with thermal processing and end form-forming processing of semi-finished product. To simplify technology setting and volumetric deformation of copper ingot are performed at temperature 630-. Thermal processing is carried out through heating copper ingot to temperature 660-740 °С till setting ingot and cooling to temperature not higher than after volumetric deformation, and end form forming processing is carried out with turning processing of semi-finished article.
