FIELD: metallurgy. ^ SUBSTANCE: procedure consists in loading charge of various composition and dimension into melting installation, in melting with flare of plasmatron or electron beam producing melt of metal, and in correction of melting process with consideration of parametres change. Surface of melts is thermo-graph scanned in infra-red range of heat radiation with determination of temperature field and thermal image recording. At local changes of the range of temperature field in the direction of temperature decrease, when charge is melted not completely, temperature of melt surface is equalised by correction of trajectory of plasmatron flare transfer of electron beam directing it on sections of surface with reduced temperature. ^ EFFECT: stabilisation of melt temperature and maintenance of maximal area of melt surface on cold bottom. ^ 3 cl, 1 dwg, 2 ex |
