摘要

1. A method of producing seamless hot boiler and steam pipes of 426 × 21-70, 465 and 530 × 25-75 × 30-75 mm from heat resistant steel 10H9K3V2MFBR-III for power equipment with supercritical steam parameters, including the smelting of metal recycling tube blanks method eleelektroshlakovogo remelting as solid ingots of the size of 1750 ± 615 × 50 mm, machining - refacing solid ingots in billet size ingots 1750 ± 600 × 50 mm, drilling a central hole bullion - workpieces diameter of 100 ± 5.0 mm, the heating in-the-blanks ingots to plasticity temperature, firmware ingots, blanks in a mill helical rolling a billet sleeve, heating sleeves, preforms with hot or cold posad to plasticity temperature, firmware - rollers of sleeves, blanks mill helical rolling sleeve on mandrels having a diameter selected depending on the geometric dimensions of the sleeves, the sleeves on piligimovyh rolling mills in tube size 426 × 21-70, 465 and 530 × 25-75 × 30-70 mm extracts, depending upon the diameter and wall thickness, hot saw segment D dressing process waste - piligimovyh seed heads and ends, straightening, heat treating, etching, ultrasonic inspection and acceptance of pipes, characterized in that the tube size 426 mm × 21-70 produce hollow electroslag remelting ingots measuring 620 × × vn.280-380 3200 ± 50 mm, which grind and the bore in the hollow billet ingot size 600 × × vn.300-400 3200 ± 50 mm, bars, billets are heated in reheating furnace to a temperature of 1190-1210 ° C and rolled at 8-16 TPU " with a pilger pipe size 426 mm × 21-70 μ with extracts from 1.94 to 5.63, bol
