PROCESS ENGINEERING CONTROLS IN A continuous casting machine of casting BEI, BEI of casting AND IN THE MANUFACTURE OF A TRANSITION PIECE

摘要

The present invention relates to a respective method of operating a continuous casting machine (1) at the start of casting, at the end of casting and for the production of a transition piece (21). The object of the invention is to improve the quality of the strand ends (16, 18), and preventively to protect the continuous casting machine (1) during the application of the method from damage. This object is achieved by a method for operating a continuous casting machine (1) at the start of casting by the following additional method steps: detecting a position of initial strand (16) in the strand guide (4); after the strand beginning (16), preferably an upper end (17a) of the strand starting region (17) has passed through the pair of adjustable strip guide rollers (5): Starting of the pair of the strand (2) so that the pair of contacts the strand (2) ; Cooling the strand initial region (17) with Q Qnom, said cooling nozzle (10) has a refrigerant quantity Q a nominal amount of coolant to the strand Qnom initial region (17) ausbringt smaller; and cooling the extruded body (20) with Q ~ Qnom, said cooling nozzle (10) has a refrigerant quantity Q is substantially equal to the strand Qnom ausbringt main part (20).
