Analysis of Atypical Breakout During Radial Continuous Casting of Slab in the Straightening Zone II. Analysis of the Causes of the Breakout by Application of the Theory of Physical Similarity

Original language description

The so called secondary cooling zone, which is divided into thirteen sections, is an important part of the CCM. In this zone, specifically in the area of the beginning of slab straightening, 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-metalic slag inclusions. 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. With useof dimensional analysis altogether 8 criteria of similarity were derived according to the ?-theorem. Table of 12 technological, geometrical and thermo-physical dimensional quantities was compiled for these criteria, which characterise bo
