Abstract (en)

[origin: EP0881017A2] The method concerns production of continuously cast (preferably steel) billets (7). A process parameter determined during casting is compared with a limit value, and the result is used to decide on the subsequent treatment of the billet. Either the continuous billet (7) or the separated billet (7') still in its hot state is machined to remove its surface or near-surface faults, with the machining process activated and deactivated on the basis of relevant process parameters. The installation includes a machine (10) for machining at least one surface region of the billet (7) or (7'). This machine is controlled on the basis of process parameters such as casting speed, melt temperature, melt level fluctuations in the mould (6), the chemical composition of the melt etc.
