Abstract
Through Kawasaki Steel Corporation's plating experience consecutively with Cr, Ni and MC (Multi-Coating) on the inner surface of the continuous casting mould, a Ni-Fe (4–10%) alloy has been newly developed for a single layer plating. Auxiliary anodes are adapted for the assembled mould plating practice to obtain a plating layer uniform in thickness along the horizontal section. Tapered plating technique is also developed to realize thin plating at the upper part of the mould in consideration of high thermal conductivity, and thick plating at the lower part from the viewpoint of good wear resistance. Ni-Fe plating has a higher heat conductivity than Ni plating and MC, and shows an excellent wear resistance at higher temperatures such as 400°C. Commercial application of the tapered single layer Ni-Fe plating proved a longer mould life, with mould cost per ton of strand reduced by 30% for bloom and 70% for slab.
