Abstract

The aim of the invention is to develop a hot rolling unit, comprising at least one continuous casting unit (1) with a post-arranged furnace (4), followed by a roughing stand (5) and, over a strip edge guide, a soaking furnace (15) and finishing train, such that downtime is reduced to a minimum level and even during said downtime, as well as in planned cases of withdrawal of pre-strip material, the pre-strip (14), behind the roughing stand in the soaking furnace, can be separated off from the normal rolling cycle. Said aim is achieved, whereby the strip edge guide has a length of at least 4 m, the soaking furnace has, or is preceded by, at least one device for recognition of the strip edge position, the soaking furnace has a pivoting cover segment (30-32), a discharge device (29) may be displaced at least alongside the soaking furnace, running in the longitudinal direction thereof and the devices for determining the strip edge position have analytical units (14) and an emergency breaker device and/or a device for releasing emergency cutters.
