Abstract
The paper compares the quality of the macrostructure of the axial zone of thick slabs with a thickness of 350 mm made of strength class K60 pipe steel with soft reduction and without it. Data on changes in the content and zonal chemical heterogeneity of several elements over the thickness of the workpieces are presented. Soft compression during the casting of slabs improves the quality of the macrostructure of the axial zone of the workpieces.
