Abstract (en)

[origin: WO2013083391A1] The present invention relates to in each case one method for the operation of a strand casting machine (1) at the beginning of casting, at the end of casting, and during the manufacturing of a transition piece (21). The problem addressed by the invention is that of - improving the quality of the strand ends (16, 18) and - preventatively protecting the strand casting machine (1) against damage during the implementation of the method. Said problem is solved by means of a method for the operation of a strand casting machine (1) at the beginning of casting by means of the following additional method steps: - detecting a position of the beginning of the strand (16) in the strand guide (4); - after the beginning of the strand (16), preferably an upper end (17a) of the beginning region of the strand (17) has passed the pair of adjustable strand-guiding rollers (5): adjusting the pair against the strand (2) such that the pair makes contact with the strand (2); - cooling the beginning region of the strand (17) with Q < QNenn, wherein the cooling nozzle (10) discharges a coolant flow rate Q lower than a nominal coolant flow rate QNenn onto the beginning region of the strand (17); and - cooling the main part of the strand (20) with Q ≈ QNenn, wherein the cooling nozzle (10) discharges a coolant flow rate Q substantially equal to QNenn onto the main part of the strand (20).
