Abstract (en)
[origin: EP0727500A1] Metal blocks, in particular, those of steel and alloys on nickel and cobalt basis, are produced by melting of self-consuming electrodes under an electrically conductive slag in an atmosphere of controlled composition. Melting of the electrode takes place in a gas-tight space bounded by the slag bath surface, the wall of a mould (20), and a mould hood (24). Electrode change takes place by removing the hood (24) from the mould and replacing it with another hood (24a). The electrode rod (26) has a gas-tight fit with the hood opening (28).
