摘要

1. A process for the production of pig pipe size 292 × 12 mm TPU 8-16 "with pilger billets from ingots electroslag remelting nizkoplastichnyh steels 04H14T3R1F-W and W-04H14T5R2F a boron content from 1.3 to 3.5% for manufacturing hexagonal pipe-size blanks "turnkey" 257 + 2,0 / -3,0 × 6 + 2,0 / -1,0 × 4300 + 80 / -30 mm for compact storage in pools of NPP and transportation of spent nuclear fuel comprising electroslag remelting ingots casting size 480 × 70 or 1750 ± 1675 ± 500 × 70 mm, refacing ingots on the outer surface to have Dalen casting defects origin in ingots, billets measuring 460 ± 1 750 ± 10 × 70 or 10 × 480 ± 1 675 ± 70 mm, drilling a central hole diameter of 100 ± 5.0 mm, heating the ingots, billets to plasticity temperature, firmware ingot billets in mill helical rolling sleeve vn.295 size 470 × × 480 × 2370-2800 and 2310-2710 mm × vn.295 with extracts from 1.41 μ to 1.57, rise of δ diameter from 0 to 4.5 % and planted Δ from 0 to 2.4%, respectively, the rolling of sleeves in pilger with backing rings carbonaceous size 480 × × vn.295 250-300 mm, for a partial removal pilig Ream heads on carbon metal in the caliber of 295 mm with an angle transverse to release polishing portion 20 ° on the mandrel diameter of 264/265 mm in steel making tube-lash size 290 × 12 × 290 × 21000-24000 and 21500-25000 × 12 mm stretch μ = 10,0-10,7 and swaging diameter Δ = 37,7-39,0%, segment hot saw cutting process waste - pilger seed heads and ends, cutting of pipe-lashes on two tubes of equal length for straightening tubes six-high leveler using rolling heating temperature, cutting of the workpiece into two tubes - not less than 5000 times range length
