Characteristics of high speed steel casting at billet CCM of ОАО CHMK

Characteristics of 2 high-speed CCMs for billets in oxygen-converter shops of ОАО ChMK have been considered. The main problems of billet production at high-speed CCMs are to ensure uninterruptible technology «heat to heat», i.e. without loss of strands and emergency stoppage of heat sequences, as well as to provide the quality of continuously cast billet without defects. It was shown that for provision of high productivity and quality of cast billets is necessary to carry out the correction of the steel chemical composition.
