from the primary melting furnace and solidification in the continuous casting or ingot mould. Today, most of the melt treatment steps involved are essentially carried out in the ladle, which has thus changed from a simple transfer or pouring means to a metallurgical treatment vessel. As a result, 'ladle metallurgy' has evolved into a fixed term.
