1. Способ получения высокопрочной стальной полосы, в котором расплавленную сталь разливают по меньшей мере в одной установке (1) для непрерывной разливки с одной или более поточными линиями для получения сляба и, используя тепло разливки, транспортируют сляб через печь (7), подвергают черновой прокатке в средстве (10) для черновой прокатки и чистовой прокатке в средстве (14) для чистовой прокатки для получения стальной полосы нужной конечной толщины, и в непрерывном, бесконечном или полубесконечном процессе сляб подвергают черновой прокатке преимущественно в аустенитном диапазоне в средстве (10) для черновой прокатки и прокатывают в аустенитном диапазоне в средстве (14) для чистовой прокатки, или прокатывают по меньшей мере в одной клети средства (14) для чистовой прокатки в двухфазном аустенитно-ферритном диапазоне, и после выхода из средства (14) для чистовой прокатки прокатанную полосу быстро охлаждают для получения нужной структуры.1. A method of obtaining a high-strength steel strip, in which molten steel is poured in at least one installation (1) for continuous casting with one or more production lines to obtain a slab, and using the heat of casting, the slab is transported through the furnace (7), subjected to roughing rolling in the means (10) for rough rolling and finishing rolling in the means (14) for finishing rolling to obtain a steel strip of the desired final thickness, and in a continuous, endless or semi-infinite process, the slab is subjected to rough rolling mainly in the austenitic range in the tool (10) for rough rolling and rolled in the austenitic range in the tool (14) for finish rolling, or in at least one stand, means (14) for finish rolling in the two-phase austenitic-ferritic range, and after exit from the means (14) for finishing rolling the rolled strip is quickly cooled to obtain the desired structure. 2. Способ по п. 1, отличающийся тем, что полосу прокатывают в устройстве (14) для чистовой прокатки при температуре, при которой имеется нужное количество феррита, причем полосу, выходящую из средства (14) для чистовой прокатки быстро охлаждают до температуры ниже Ms (начало образования мартенсита) в температурном диапазоне, в котором образуется мартенсит.2. The method according to p. 1, characterized in that the strip is rolled in the finish rolling device (14) at a temperature at which the desired amount of ferrite is present, and the strip exiting the finish rolling means (14) is rapidly cooled to a temperature below M s (the beginning of the formation of martensite) in the temperature range in which martensite is formed. 3. Способ по п. 1, отличающийся тем, что полосу прокатывают в устройстве (14) для чистовой прокатки при температуре, при которой имеется нужное количество феррита, и тем, что полосу, выходящую из средства (14) для чистовой прокатки, быстро охлаждают до температуры выше Ms (начало образования мартенсита) в температурном диапазоне, в котором образуется мартенсит.3. The method according to p. 1, characterized in that the strip is rolled in the finish rolling device (14) at a temperature at which the desired amount of ferrite is present, and that the strip exiting the finish rolling means (14) is rapidly cooled to a temperature above M s (the beginning of the formation of martensite) in the temperature range in which martensite is formed. 4. Способ по любому из пп. 1-3, отличающийся тем, что прокатку выполняют со смазкой по меньшей мере в одной клети, предпочтительно во всех клетях средства (10) для черновой прокатки и/или по меньшей мере в одной клети, предпочтительно в каждой клети средства (14) для чистовой прокатки. 4. The method according to any one of paragraphs. 1-3, characterized in that the rolling is performed with lubrication in at least one stand, preferably in all stands of the roughing means (10) and / or at least one stand, preferably in each stand of the finishing means (14) rolling. 5. Устройство для получения стальной полосы для выполнения способа по любому из пп. 1-4, содержащее по меньшей мере одну установку (1) для непрерывной разливки тонких слябов, печь (7) для гомогенизации сляба, который может быть подвергнут обжатию до предварительного размера, и средство (14) для прокатки сляба с получением полосы нужной конечной толщины, и моталку (16) для смотки полосы, отличающееся тем, что средство охлаждения (15) с охлаждающей способностью по меньшей мере 2 МВт/м2 размещено между последней чистовой клетью средства (14) для прокатки и моталкой (16).5. A device for producing a steel strip for performing the method according to any one of paragraphs. 1-4, containing at least one apparatus (1) for continuous casting of thin slabs, a furnace (7) for homogenizing a slab that can be crimped to a preliminary size, and means (14) for rolling the slab to obtain a strip of the desired final thickness and a coiler (16) for winding the strip, characterized in that the cooling means (15) with a cooling capacity of at least 2 MW / m 2 is placed between the last finishing stand of the rolling means (14) and the coiler (16).
