摘要

1. A method of producing a hot rolled seamless smooth, threaded, boiler rooms, and special-purpose thick-walled pipes with a diameter of 273 to 630 mm for a pipe-rolling pilger installation comprising forming month program execution process sequence of the program, the heating NLZ, forgings, solid and hollow ESR ingots, billets to plasticity temperature NLZ firmware forged blanks and billets in rolling mills ESR ingots helical rolling on a mandrel in a short sleeve or sleeves -zagotovki on one of the mills, firmware-rollers of sleeves blanks on a short mandrel mill in the second helical rolling without heating or after reheating, blowing sleeves, liners for transporting pilger mill, rolling the sleeves in smooth pipes commodity general purpose, threaded, boiler, commodity and steel making pipes for special purposes in rolls with a diameter of the barrel 980 to 1045 mm calibres from 280 to 562 mm on the mandrel tapered from 1.0 to 6.0 mm depending on the coefficient of linear expansion of steel, removal techno logical trim-pilger heads and seed end, cutting of tubes in multiple lengths saws hot cutting, heated smooth general purpose and threaded pipes in bushing section or furnace with walking beams, calibration tube, transport pipes on shlepperah with rotation straightening tubes in six-high leveler , provisional acceptance and inspection of pipes, with stippling applying chamfering to smooth pipes, general purpose, applying trimming pipes chamfer rifled tubes threading of casing couplings and before navertku
