The analysis of the causes of cross cracking in concast slab via two numerical models
Original language description
This paper deals with the causes of a transversal crack in a steel slab with 145x1300 mm cross-section by means of two numerical models. The chemical microheterogeneity of the steel matrix and the surface of cracking have been estimated by means of X-raymicro-analyser JEOL JXA 8600/KEVEX. The analyses of Al, Si, P, Ti, Cr, Mn and Fe on the metallograpic samples of matrix of steel, of the neighbourhood of cracking and of the surface of cracking have been realized. There has been found out that the crosscracking is characterized of high macro-heterogeneity of manganese, carbon and sulphur. The causes of cross cracking have been explained by means of a thermokinetic calculation of a slab transient temperature field. There has been confirmed that two solidification cones are formed asymmetrically in the course of slab solidification and it is probable that the asymmetrically passing crack initiated on one of these two apexes.
