Abstract
The macrostructure of continuous-cast high-carbon steel (in particular, rail steel) billet may be improved by introducing macrocooling additives to prevent overheating of the melt in the casting-machine mold. The liquidus temperature of the macrocooling additives is 5–20°C lower than for the cast steel. Macrocooling strip is alloyed with boron, which ensures additional modification of the rail steel.
