Method for quantitative evaluation of intial solidfication layer in continuous casting slab

摘要

The present invention relates to a method for quantitatively evaluating the initial solidification layer of continuously cast slabs and, more particularly relates to the quantitative assessment of the initial solidified layer of continuously cast slabs which can quantitatively evaluate the thickness of the initial solidification of the slab layer . Quantitative assessment of the initial solidification layer of the continuous casting slab according to the present invention for achieving the object as described above, comprising the steps of extracting the tissue images using the image processing apparatus from a sample of the slab ; Step to separate the boundary layer of the initial coagulation in tissue image; And by measuring the position of the initial solidified layer thickness by using the image processing apparatus is characterized in that it comprises a step for calculating a quantitative index of initial solidification layers . ;
