On the mechanism and causes of cross cracking in concast low alloy manganese steel slab

Popis výsledku v původním jazyce

The paper deals with surface morphology, the mechanism of origination and causes of cross cracking of concast low alloy manganese steel slab. The cross cracking was identified in steel slab with sectional size 145x1300 mm and the length of the asymmetrical cracking was approximately 600 mm. The light microscopy and the scanning electron microscopy have been applied for determination of metallographic structure of steel and for the study of micro-morphology and the trajectory of cracking. The chemical microheterogeneity of the steel matrix and the surface of cracking have been estimated by means of X-ray micro-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 neighbourhoodof cracking and of the surface of cracking have been realized. There has been found out that the cross cracking is characterized of high macro-heterogeneity of manganese, carbon and sulphur. The causes of cross cracking have been explaine
