Installation for electroslag melting of heavy-weight metal ingots

摘要

An installation has a hollow cooled mould with a bottom plate having a cooled protrusion which partially enters the cavity of the cooled mould from underneath and forms the bottom of the mould at the beginning of melting. The protrusion is of a height exceeding that of the ingot forming walls of the cooled mould, and of a cross section allowing the cooled mould to be lowered to a level at which the ingot forming section of the cooled mould wall is below the upper end face of the cooled protrusion. The installation is compact in size and permits the use of a crane for upward removal of an ingot from the cooled mould.
