Method and device for hot rolling metal rolling stock

The invention relates to a method for hot-rolling a metal rolled material using a plurality of rolling devices arranged in a rolling train, the method comprising providing a semi-finished product having a thickness greater than or equal to 150 mm as the rolled material, the rolled material is rolled in a rolling train from a first large open-rolling cross-section by a step-by-step thickness reduction to a relatively smaller target cross-section, characterized in that the thickness reduction from the open-rolling cross-section to the target cross-section takes place only by means of a single rolling device or by means of a plurality of similar rolling devices of a single rolling stand type. The invention also relates to a hot rolling system for carrying out the method. 本发明涉及一种用于热轧金属轧材的方法，所述方法使用多个布置在轧制机组中的轧制装置，其中，所述方法包括提供厚度大于或等于150mm的半成品作为轧材，其中，所述轧材在轧制机组中从第一大开轧横截面通过逐步的厚度减小而轧制成相对更小的目标横截面，其特征在于，从所述开轧横截面到所述目标横截面的厚度减小仅借助单个轧制装置或利用单个轧机机架类型的多个同类轧制装置实现。本发明还涉及一种用于执行所述方法的热轧设备。
