Two versions of TSK-K-20 mixture are selected for the casting of 300 × 340 mm rail-steel billet on a radial continuous-casting machine: TSK-K-20B1 and TSK-K-20B1m. Their chemical composition and thermophysical characteristics are investigated. The mixtures ensure the required surface quality of the billet and the rolled product; the life of the submersible nozzles is at least 20 h. At present, these mixtures are used instead of ShOS-1 mixture for continuous casting in the electrosmelting shop.
