摘要

1. A method of manufacturing hot-rolled seamless pipes of 530 mm × 25-60 for steam boilers, steam plants and reservoirs with high and supercritical steam from steel 10H9MFB-III comprising electroslag remelting ingots smelting, machining, turning of ingots, billets ingots , drilling ingot billet center hole diameter of 100 ± 5 mm, heating the ingots, billets to plasticity temperature, their firmware in helical mill rolling billets liner cooling liner blanks, D Mounting liner blanks if necessary, reheating the liner blanks with cold posad to plasticity temperature, flash-rollers of sleeves mill blanks in a helical rolling sleeve rolling pilger mills on sleeves into salable tube size 530 × 25-60 mm, heat treating, etching, edit, ultrasonic inspection and acceptance of a tolerance on pipe diameter + 1.25 / -1.0% and a wall thickness of 20 + / -5.0%, characterized in that the tube size 530 mm × 25-30 made from hollow ingots electro-slag remelting, ingot hollow grind and stretch achivayut a hollow billet ingot size 660hvn.490 × 3200 ± 50 which is heated to a temperature of 1180-1190 ° C and rolled at 8-16 TPU "with pilger into pig tube size 550 × 45 × 550 × 5300-5500 and 48 × 5000-5200 with hoods respectively, μ = 2,10, μ = 1,99 and planted in the diameter of 16.7%, with feeds cores in the deformation zone m = 20-22 mm, cut process waste hot saw cutting rule in a six-high leveler, heat-treated, re-authorize a six-high leveler with the metering tubes in total curvature length not more than 5.0 mm, the tube is transmitted to uch
