Breakout of a Slab as the Result of Changes in the Thermo-physical Properties of Continuously Cast Steel
Original language description
The so called secondary cooling zone is an important part of the continuous casting machine. In this zone a breakout may occur due to an increase of the local and temperature heterogeneity of steel, resulting from an increase of the stress caused by bending of the slab and by high local concentration of non-metallic slag inclusions. Changes of the chemical composition of steel during continuous casting are particularly dangerous. In the event that two melts are cast one right after another, i.e. if the melt of steel with chemical composition A ends and it is immediately followed by the steel B, it may automatically stop the CCM and an atypical breakout may take place. It happened during continuous casting of the slab. 250x1530 mm in the area of straightening, 20 minutes after flying change of tundish. In the present paper, by employing the dimensional analysis, eight dimensionless numbers are derived. If the values of this dimensionless numbers for two immediately followed steels significant differs, the atypical breakout may take place.
