摘要：
The invention relates to a method for producing hot strips (18) from a deformable lightweight steel which is especially suitable for cold deep drawing and includes as main elements Fe, Mn, Si and Al, and which has a high tensile strength and TRIP and/or TWIP properties. Melt is cast close to its final dimension in a horizontal continuous strip casting installation (1) under a protective gas in order 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. According to the invention, the pre-strip is passed through a device (10) 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 carried out in inline or in a decoupled manner in dependence on the ratio of casting speed to rolling speed.
