Rolling of nickel base hardly deformable alloys in four-roller mills

Results are presented of the optimization procedure relating to a new rod rolling technology in the case of hard-to-deform nickel alloys of the type EhP220VD and some others on four-high mills. The rods 22, 16 and 12 mm in diameter being rolled on the mills MK-165 and MK-200 show an adequate surface quality, high mechanical and heat-resistance properties. The main principles of the rolling technology as applied to the treatment of hard-to-deform nickel alloys developed
