FIELD: metallurgy.
SUBSTANCE: method involves casting by electroslag remelting of hollow ingots from low-ductility steel "04Х14Т5Р2Ф-Ш" with boron content of 2.0 to 3.0% with the dimension of 470±5×inner270±5×3000±25 mm. Bottom and shrinkage parts of ingots with height of 0.06-0.07 and 0.08-0.10 respectively of total height of ingots are cast from ductile carbon-bearing grades and form seed ends and pilger heads at rolling of semi-finished pipes. Hollow ingots are turned and bored into hollow cakes with the dimension of 455±5×inner280±5×3000±25 mm, heated to the temperature of 1030-1050°C and rolled into semi-finished pipe lengths on mandrels 263/264 with drawing µ of 9.79 to 10.98 and swaging as to diameter Δ of 36.8 to 38.3%. Pilger heads and seed ends are removed, cut into pipes of multiple length, and then, into two shells of equal length of at least 5000 mm. Shells of equal length are turned and bored into pipe shells with the dimensions of 278.7±1.8×5+1.5/-1.0 mm and shaped into hexagonal pipes with the flat-to-flat dimensions of 252.6±1.8×1.5/-1.0×4300+80/-30 mm.
EFFECT: reduction of consumption of "04Х14Т5Р2Ф-Ш" steel.
