A device for producing hot-rolled metal strips has a casting machine that produces and transports slabs in a transport line of the casting machine. A rolling mill forms the slabs into corresponding metal strips during transport along a transport line of the rolling mill. A combination transport and temperature-influencing device is arranged between the casting machine and the rolling mill transports the slabs at least along the transport line of the rolling mill, feeds the slabs to the rolling mill and sets the temperature of the slabs to a rolling temperature. A surface device is arranged between the casting machine and the combination transport and temperature-influencing device and processes and/or treats and/or inspects at least one of the surfaces of the slabs. A temperature-influencing device is arranged between the casting machine and the combination transport and temperature-influencing device and modifies the temperature of the slabs.

A steel continuous-casting machine including: a cooling apparatus that is configured to cool cast steel with water, wherein: the cooling apparatus includes a plurality of cooling-water-discharging nozzles configured to be arranged in a width direction of the cast steel, and the plurality of cooling-water-discharging nozzles are configured to be arranged such that spray discharge surfaces of adjacent cooling-water-discharging nozzles of the plurality of cooling-water-discharging nozzles that are adjacent to each other in the width direction of the cast steel do not overlap.

A process that produces a microalloyed steel in an integrated casting-rolling plant having a continuous casting machine with a mold, a single- or multi-stand prerolling train, a finish-rolling train having a first stand group with at least one first finish-rolling stand and a second stand group having at least one stand cooler. A metallic melt is cast in the mold to obtain a partly solidified thin-slab strand, which is supported, deflected and cooled. The solidified thin-slab strand is rolled by the prerolling train to obtain a prerolled strip that is finish-rolled in the first stand group to obtain the finish-rolled strip, which is fed to the second stand group and force-cooled in the second stand group, the finish-rolled strip having a thickness that results in a cooling rate of the core of the finish-rolled strip in the second stand group greater than 20 C./s and less than 200 C./s.
