ROLLING MILL FOR PRODUCING BAR Russian patent published in 1994 - IPC

FIELD: rolling of metal. SUBSTANCE: mill has two parallel production lines 19,20 interconnected with vehicles. One of the lines has two reverse stands 6,7 of screw rolling, cutting device 8, and cooler 9. The other line has stand for rolling up pinches, cutting device 15 for cutting bar over bottom of pinches, cooling device 16, furnace 17 for preliminary heating, and heating furnace 18. There are three working variants: for deformation of 770-800 mm ingots of one and two phase titanium alloys in beta-region for making 250- 350 mm bar; for deformation ingots of one and two phase alloys for making rod of 130-250 mm diameter or less in beta-region; for deformation of ingots of two phase titanium alloys for making rod of 130-200 mm diameter with a given alpha+beta structure in alpha+beta region. EFFECT: enhanced efficiency. 1 dwg, 1 tbl
