Abstract:
A method for the endless production of hot-rolled, flat products from thin cast strip on an installation comprising a single-stand roughing train, a multi-stand finishing train, a delivery roller table with devices for cooling the hot-rolled strip and upstream and downstream coiling machines for coiling up the hot-rolled strip, the method comprising the steps of: cooling the strip cast in a thickness of 5-18 mm in a controlled manner under an inert gas atmosphere before reaching the single-stand roughing train so that no other method steps take place between the cooling of the strip in the inert gas and the introduction of the strip to the roughing train; one of selectively cooling, heating and maintaining the temperature of the hot pre-rolled strip in a controlled manner in a device downstream of the roughing train; and subsequently heating edges of the hot-rolled strip.
