【 摘 要 】

The paper introduces the influence of the control over steel ingot solidification upon the quality characteristics of carbon steels. The laboratory experiments focused on the solidification control of steel ingots with cylindrical cross-section, by addition of crystallizing germs (micro-coolers) in their central area, in order to influence their inner structure and quality characteristics. The use of graphical and analytical correlations allows the establishing of optimal technological domains of variation for the steel casting parameters, with use of micro-coolers, in order to obtain the desired values for their mechanical characteristics.
