Analysis of operation conditions of knives for hot cutting of metal was performed and the main types of their working edge wear were determined. Self-shielded flux-cored strip PL-Np-40Kh2N6G2S2M2FB (PL-AN183) and specialized machine UD-298M were developed for automatic surfacing of blooming mill hot cutting knives. Process automation is conducted through application of SU-360 control system, which is based on modern components. Application of the new flux-cored strip and specialized surfacing machine allowed 2 to 3 times increase of surfacing efficiency. Here, surfaced knife resistance increased 1.5 to 2 times. This development has been successfully introduced at Company «Arselor Mittal Krivoj Rog». 5 Ref., 2 Figures.
