Abstract
The technology of soft reduction of continuously cast 350 mm thick slabs of pipe steel is considered in the work. Variants of reduction with different intensities in two and three segments of the secondary cooling zone of the continuous casting machine were tested. Analysis of the quality of the macrostructure of slabs cast at different speeds with two-segment reduction is done. Recommendations of the parameters of the soft reduction mode are given for obtaining the internal structure of castings with a lower degree of defect development.
