Abstract

The invention relates to a method and an installation for the production of hot-rolled steel strip from continuously cast material, preferably thin slabs with working steps of a CSP method taking place in succession at the same temperature, the thin slabs leaving a soaking furnace being heatable to temperatures above the maximum temperature achievable in the soaking furnace, the thin slabs being left a sufficient time to recrystallise after the roughing pass, and the thin slabs then being cooled to the rolling temperature for the finishing train.
