Abstract
Disclosed are a method and an installation for producing steel products () having an optimum surface quality, especially extremely low carbon contents (UCL steel or IF steel), nitrogen contents, total oxygen contents, high-strength or stainless steel qualities. According to the invention, the liquid steel is cast into a thin slab () from a process route (, or) that is selected according to the desired final structure () based on an electric-arc furnace (), is descaled, cut into billets () having a partial length, optionally descaled once again, subjected to final descaling downstream from a holding furnace (), milled in a finishing mill train (), rolled up in a rolling station () located downstream from the last finishing mill stand () or downstream from a cooling section (), and the final structure () is adjusted in the cooling section () according to the desired steel quality by cooling on a run-out roller table (), whereupon the rolling stock () is completely rolled up in a second rolling station ().
