1. Способ изготовления ленты из низколегированной теплоустойчивой стали, включающий двухпередельную холодную прокатку горячекатаной полосы-подката с промежуточной и окончательной термообработками, отличающийся тем, что первый холодный передел ведут с относительной степенью деформации 40- 60%, упомянутые термообработки ведут соответственно в три и две стадии, при этом на первой стадии промежуточной термообработки ленту-подкат выдерживают при 500-550oC в течение 4,5-5,0 ч, на второй стадии промежуточной термообработки ленту-подкат выдерживают при 800-820oC в течение 16-17 ч, на третьей стадии промежуточной термообработки выдержку осуществляют в присутствии паров воды с температурой точки росы от 10 - 20oC; на первой стадии окончательной термообработки прокатанную ленту выдерживают при 500-550oC в течение 2,5-3,0 ч, а после второй стадии окончательной термообработки упомянутую ленту охлаждают до 600-650oC со скоростью не менее 3oС/мин.1. A method of manufacturing a strip of low-alloy heat-resistant steel, including double-pass cold rolling of a hot-rolled strip with intermediate and final heat treatments, characterized in that the first cold redistribution is carried out with a relative degree of deformation of 40-60%, said heat treatments are carried out in three and two stages, respectively , while in the first stage of the intermediate heat treatment, the tape-tackle is kept at 500-550 o C for 4.5-5.0 hours, in the second stage of the intermediate heat treatment of the tape-tackle is held at 800-820 o C for 16-17 hours, in the third stage of the intermediate heat treatment, exposure is carried out in the presence of water vapor with a dew point temperature of 10 - 20 o C; in the first stage of the final heat treatment, the rolled strip is kept at 500-550 ° C for 2.5-3.0 hours, and after the second stage of the final heat treatment, the ribbon is cooled to 600-650 ° C at a speed of at least 3 ° C / min. 2. Способ по п. 1, отличающийся тем, что на второй стадии окончательной термообработки прокатанную ленту выдерживают при 780-850oC в течение 3-4 ч, после чего ее охлаждают до 600-650oC со скоростью 3-200oC/мин.2. The method according to p. 1, characterized in that in the second stage of the final heat treatment, the rolled strip is held at 780-850 o C for 3-4 hours, after which it is cooled to 600-650 o C at a speed of 3-200 o C / min 3. Способ по п. 1, отличающийся тем, что на второй стадии окончательной термообработки прокатанную ленту выдерживают при 850-900oС в течение 3-4 ч, после чего ее охлаждают до 600-650oС со скоростью 3-100oС/мин.3. The method according to p. 1, characterized in that in the second stage of the final heat treatment, the rolled strip is kept at 850-900 o C for 3-4 hours, after which it is cooled to 600-650 o C at a speed of 3-100 o C / min 4. Способ по п. 1, отличающийся тем, что на второй стадии окончательной термообработки прокатанную ленту выдерживают при 900-980oС в течение 3-4 ч, после чего ее охлаждают до температуры 600-650oС со скоростью 3-70oС/мин.4. The method according to p. 1, characterized in that in the second stage of the final heat treatment, the rolled strip is kept at 900-980 o C for 3-4 hours, after which it is cooled to a temperature of 600-650 o C at a speed of 3-70 o C / min
