METHOD FOR PRODUCING PIPE pig large and medium-diameter ingots and billets of titanium alloys AT TPU With pilger

摘要

1. A process for the production of pig pipes of large and medium-diameter ingots and billets of the alloys based on titanium on a TPU pilger comprising ingot casting in vacuum-arc furnaces, followed by forging and machining - turning them into the blank, drilling the central hole diameter of 100 ± 5.0 mm, the charging of blanks in the muffle, put on a clean methodical hearth heating furnace, heating to plasticity temperature, in the host firmware helical rolling in the sleeve, the rolling of sleeves in steel making pipe TPU pilger using backer carbon rings for partial removal pilger heads on carbonaceous metal periodic mill stopping and removal by grinding adhering titanium alloy rims flannel part rolls segment saw hot cutting process waste - not completely run-pilger heads and seed end, edits of mother tubes using rolling heating temperature, machining in boring and turning of commodity or steel making pipes for Later of their redistribution on mills HPT, characterized in that after the n-th rolling of mother tubes amount of titanium-based alloys for the removal of alloy rims produce rolls rolling the tube of a given size carbon stali.2 mark. A method according to claim 1, characterized in that the number of mother tubes rolled from alloys based on titanium alloy to form a flange sticking to the rollers and rolling the tuning tube defined by the expression where ΣL = 50-55 - total length of mother tubes made of alloys based on titanium rolled in caliber in
