Abstract

See full text

A method for operating a continuous casting machine (1) at the start of casting, at the end of casting and when producing a transitional piece (21) for improving the quality of the ends of the strand (16, 18), and protecting the machine from damage. At the start of casting, perform the following additional method steps: recording a position of the beginning of the strand (16) in the strand guide (4); after the beginning of the strand (16) and after an upper end (17a) of the beginning region of the strand (17), has passed a pair of adjustable strand guiding rollers (5) adjusting the roller pair to touch the strand (2); cooling the beginning region of the strand (17) by the cooling nozzle (10) delivering an amount of coolant Q less than a nominal amount of coolant Qnom to the beginning region of the strand (17); and cooling the main part of the strand (20) by the cooling nozzle (10) delivering an amount of coolant Q that is substantially equal to Qnom to the main part of the strand (20).
