<p>In a method for producing hot strips from a deformable lightweight steel which includes as main elements Fe, Mn, Si and Al, melt is cast close to its final dimension in a horizontal continuous strip casting installation under a protective gas to form a pre-strip between 6 and 20 mm, and the temperature of the pre-strip is adjusted after complete solidification and before the beginning of a hot-rolling process. The pre-strip is passed through a device under a protective gas for homogenization in concert with a selective maintenance of the temperature, cooling or heating, and subsequently subjected to a hot-rolling process having at least one pass with a total degree of deformation of at least 50%, and is then reeled as a hot strip following the cooling process. The hot-rolling process is executed in-line or in decoupled manner depending on the ratio of casting speed to rolling speed.</p> |
