Способ изготовления стальной полосы, заключающийся в том, что осуществляют непрерывную разливку стальной полосы, направляют полосу через камеру с атмосферой, препятствующей окислению поверхности полосы и последующему образованию окалины, подают полосу через прокатный стан, в котором ее подвергают прокатке в процессе изготовления, пропускают прокатанную полосу через окалиноломатель для удаления с нее окалины после выхода из прокатного стана, и подают прокатанную и очищенную от окалины полосу в моталку.1. A method of manufacturing a steel strip, which consists in the continuous casting of a steel strip, direct the strip through a chamber with an atmosphere that prevents oxidation of the surface of the strip and the subsequent formation of scale, feed the strip through a rolling mill, in which it is subjected to rolling during the manufacturing process, the rolled strip through the descaler to remove scale therefrom after exiting the rolling mill, and the rolled and descaled strip is fed to a coiler. 2. Способ по п.1, в котором в прокатном стане осуществляют горячую прокатку полосы при температуре в интервале от 750 до 1250°С.2. The method according to claim 1, in which in the rolling mill carry out hot rolling strip at a temperature in the range from 750 to 1250 ° C. 3. Способ по п.1 или 2, в котором полосу выпускают из камеры до ее пропускания через прокатный стан.3. The method according to claim 1 or 2, in which the strip is released from the chamber before it passes through the rolling mill. 4. Способ по п.1 или 2, в котором прокатный стан расположен внутри камеры, чтобы полоса проходила через прокатный стан до ее выхода из камеры.4. The method according to claim 1 or 2, in which the rolling mill is located inside the chamber, so that the strip passes through the rolling mill until it leaves the chamber. 5. Способ по любому из пп.1-4, в котором осуществляют непрерывную разливку полосы, удерживая литейную ванну расплавленной стали на паре охлаждаемых литейных валков, образующих между собой зазор, и получают затвердевшую полосу путем вращения валков во взаимно противоположных направлениях, чтобы затвердевшая полоса перемещалась вниз от зазора.5. The method according to any one of claims 1 to 4, in which the continuous casting of the strip is carried out, holding the molten steel casting bath on a pair of cooled casting rolls forming a gap between them, and a hardened strip is obtained by rotating the rolls in mutually opposite directions so that the hardened strip moved down from the gap. 6. Способ по любому из пп.1-5, в котором атмосферу в камере образуют инертными или восстановительными газами.6.
