发明名称 Electroslag facing process
摘要 The disclosed process consists in filling the gap between a billet and the wall of a sectional mould with a molten slag in at least two stages. When the first portion is poured in, the gaps between the sections of the mould are filled. Once the slag in the gaps is solidified completely, voltage is supplied and the second and next portions of the slag are added. The creation of an electromagnetic field inside the mould takes place following the starting of the cladding process. The liquid metal is then added for the cladding process, which is carried out by means of the stable rotation of the slag and metal. The process can be carried out with varying levels of slag inside the current-carrying part of the mould. The billet can be preheated at the short-circuiting conditions prior to the cladding process.
