| 发明名称 | Method for producing a hot rolled strip and hot rolled strip produced from ferritic steel | ||
| 摘要 | The invention relates to a method for producing a hot strip from transformation-free ferritic steel, wherein a melt is cast into a roughed strip and the latter is subsequently rolled into a hot strip. For this purpose, it is provided that the melt is cast in a horizontal strip casting facility under conditions of a calm flow and free of bending into a roughed strip in the range between 6 and 20 mm and is subsequently rolled into hot strip having a degree of deformation of at least 50%. | ||

| 主权项 | 1. A method for producing a hot strip from a transformation-free ferritic steel, comprising the steps of: casting a melt in a horizontal strip casting facility under conditions of a calm flow and free of bending to form a roughed strip having a thickness in a range between 6 and 20 mm; and rolling the roughed strip into a hot strip with a degree of deformation of at least 50%, wherein the transformation-free terrific steel has a chemical composition in weight-% of <1.8C; <30Cr; >5Al, remainder iron including unavoidable steel-accompanying elements. | ||
