The effect of heating condition for continuously-cast slabs of different cross section on the probability of corner crack formation is analyzed. Versions are considered for correction of cooling water and air flow rates in secondary cooling zone (SCZ) sprayers with the aim of optimizing the thermal profile of continuously-cast billets poured from crack-resistant steels. SCZ operating regimes are developed for the Azovstal Metallurgical Combine CBCM-6 making it possible to reduce the overall level of slab surface cleaning by 30%.
