Abstract: Method for the manufacture of a steel strip, wherein molten steel is cast into a slab, conveyed through a furnace, roughed in a roughing apparatus and finish-rolled in a finishing apparatus. The method comprises an endless or semi-endless process having either step a or step b, wherein a and b respectively comprise (a) manufacturing a ferritically rolled steel strip, wherein the slab is rolled in the roughing apparatus in the austenitic range and then cooled to a ferritic structure, and wherein the strip is rolled in the finishing apparatus at speeds essentially corresponding to the entry speed into the finishing apparatus, and (b) manufacturing an austenitically rolled steel strip, wherein the strip leaving the roughing apparatus is heated to the austenitic range and is rolled in the finishing apparatus and then cooled down to the ferritic range. In both step a and b, there is no material connection between the steel in the continuous casting machine and the steel being rolled in the finishing apparatus, and the strip is fed from the roughing apparatus to the finishing apparatus without intermediate storage. Additional steps include cutting the ferritically or austenitically rolled strip, after reaching the desired finished thickness, to portions of the desired length, and coiling the cut portions.

Abstract: PURPOSE: To obtain a high quality material, to which the hot-rolling of a carbon steel can be applied by the use of a Steckel hot-rolling mill and of which metallurgical structure is reformed. CONSTITUTION: A rolling material 1 is heated by a heating device 5 arranged between a furnace coiler 16 and the rolling mill 2 and held for a fixed time to execute again the solid-solution heating to deposited material. For minimizing the necessary heating capacity in the heating device 5, the solid-solution heating pass is made to non-rolling reduction or extremely light rolling reduction and low speed plate passing and if necessary, this pass is repeated plural times. Particularly, the solid-solution heating pass is executed just before the last rolling pass, or the rolling material temperature just before starting the rolling is controlled to un-recrystallized austenite range or ferrite range by utilizing the heating device 5 and a cooling device 6, or at least in the last rolling pass, hot-rolling oil is applied on the rolling material 1 or an accumulated rolling reduction ratio in the un-recrystallized austenite range is made to >= 50%, densirably >= 60% to prevent the coarsening of the metallurgical structure crystallization in the rolled material 1.
Abstract translation: 目的：通过使用Steckel热轧机并对其进行改性的冶金结构，获得能够应用碳钢的热轧的优质材料。 构成：轧制材料1被设置在炉式卷取机16和轧机2之间的加热装置5加热，并保持固定时间，以再次执行对沉积材料的固溶加热。 为了最小化加热装置5中的必要的加热能力，固溶加热通道进行非滚动压下或极轻的轧制压下和低速板的通过，如果需要，可以重复该次通过多次。 特别是，在最后的轧制过程之前执行固溶加热通道，或者通过利用加热装置5和冷却装置6将刚刚开始轧制之前的轧制材料温度控制为未再结晶的奥氏体范围或铁素体范围， 或至少在最后的轧制过程中，对轧制材料1施加热轧油，或者将未再结晶奥氏体范围的累积压下率设为> 50％，致密地> 60％，以防止粗化 的轧制材料1中的冶金结构结晶。
