VERFAHREN ZUR ENTSCHWEFELUNG VON EISENSCHMELZEN BEI MINIMALEM SCHLACKE-ANFALL UND EINE DAFUER GEEIGNETE VORRICHTUNG

摘要

The invention relates to a process for desulphurising irons melts with minimal slag production, and a suitable device therefor. In the process, a slag with the chemical analysis (I) and impurities arising from the raw material is taken to a temperature of 1400 to 1800 DEG C by the resistance heating of the slag by means of electrodes immersed in the slag in a tippable low-shaft furnace or an electric or pan furnace adapted for the process of the invention and with this slag the sulphur-containing irons melt is desulphurised and either discontinuously or continuously cast beneath the desulphurising slag, and the ratio between the irons melt and the slag may not exceed 10 : 1 parts by weight and the desulphurising slag is continuously and/or discontinuously regenerated.
