Abstract
The macrostructure of 10, 20, 09Γ2C, and дб steel billet (diameter 150 and 220 mm) is investigated. Regardless of the casting parameters and grade of steel, the metal in the continuous-cast billet studied contains sections distributed randomly over the length that are characterized by impermissible central porosity in tests. The nonuniform distribution of this defect over the length of the billet is due to unstable solidification of the central zone and is not eliminated in continuous casting of the steel. The research permits the adoption of a new edition of Technical Specifications TU 14-159-324-2012 for continuous-cast billet, with requirements on the extent of the central porosity.
