Claims (5)

1. Способ изготовления горячекатаной стальной ленты из полученного непрерывной разливкой полуфабриката в, по меньшей мере, две стадии деформационной обработки, каждая из которых состоит из одной или нескольких прокатных клетей, в котором раскатывают полуфабрикат на первой стадии деформации с выходной скоростью полуфабриката из установки для непрерывной прокатки, который перед второй стадией деформации наматывают без разрезания в промежуточный рулон со скоростью выхода из первой стадии деформации для того, чтобы подвергнуть промежуточный рулон как бы бесконечной чистовой прокатке, после которой его разрезают на рулоны желаемого веса и наматывают в виде готовой ленты, отличающийся тем, что на установке для непрерывной разливки отливают, по меньшей мере, 40 тонн литейного ассортимента с получением полуфабриката ленты и раскатывают на первой стадии деформации в промежуточную ленту, металлургические свойства которой изменяют путем изменения температурного режима перед намоткой промежуточной ленты и/или перед второй стадией деформации, а также путем гибкого регулирования скорости, изменяемой в пределах длины промежуточного рулона.1. A method of manufacturing a hot-rolled steel strip from a semi-finished product obtained by continuous casting into at least two stages of deformation processing, each of which consists of one or more rolling stands, in which the semi-finished product is rolled in the first stage of deformation with the output speed of the semi-finished product from the continuous installation rolling, which before the second stage of deformation is wound without cutting into an intermediate roll with a speed of exit from the first stage of deformation in order to expose between the final roll, as it were, to endless rolling, after which it is cut into rolls of the desired weight and wound in the form of a finished tape, characterized in that at least 40 tons of the casting assortment are cast on a continuous casting machine to produce a semi-finished tape and rolled out on the first stages of deformation into an intermediate tape, the metallurgical properties of which are changed by changing the temperature regime before winding the intermediate tape and / or before the second stage of deformation, as well as by flexible adjustment Ia rate variable within the length of the intermediate roll. 2. Способ изготовления горячекатаной стальной ленты из полуфабриката ленты, полученного непрерывной разливкой по п.1, отличающийся тем, что путем соответствующей регулировки параметров прокатки во время деформации промежуточной ленты внутри второй стадии деформации изменяют геометрические свойства готовых рулонов, полученных из промежуточного рулона. 2. A method of manufacturing a hot-rolled steel strip from a semi-finished tape obtained by continuous casting according to claim 1, characterized in that by adjusting the rolling parameters during deformation of the intermediate tape inside the second stage of deformation, the geometric properties of the finished rolls obtained from the intermediate roll are changed. 3. Способ изготовления горячекатаной стальной ленты из полуфабриката ленты, полученного непрерывной разливкой по пп.1 и 2, отличающийся тем, что намотку промежуточной ленты осуществляют в промежуточный рулон на оправке. 3. A method of manufacturing a hot-rolled steel strip from a semi-finished tape obtained by continuous casting according to claims 1 and 2, characterized in that the intermediate tape is wound into an intermediate roll on a mandrel. 4. Способ изготовления горячекатаной стальной ленты из полуфабриката ленты, полученного непрерывной разливкой по пп.1 и 2, отличающийся тем, что намотку промежуточной ленты осуществляют в промежуточный рулон без оправки. 4. A method of manufacturing a hot-rolled steel strip from a semi-finished tape obtained by continuous casting according to claims 1 and 2, characterized in that the intermediate tape is wound into an intermediate roll without a mandrel. 5. Способ изготовления горячекатаной стальной ленты из полуфабриката ленты, полученного непрерывной разливкой по любому из пп.1-4, отличающийся тем, что во время намотки промежуточной ленты в промежуточный рулон экранируют, по меньшей мере, кромки промежуточной ленты от охлаждения. 5. A method of manufacturing a hot-rolled steel strip from a semi-finished tape obtained by continuous casting according to any one of claims 1 to 4, characterized in that at least the edges of the intermediate tape are shielded from cooling during winding of the intermediate tape into the intermediate roll.
