Process for melting scrap iron, sponge iron and/or solid pig iron |
摘要 |
For the purpose of melting scrap iron, pelletized sponge iron in reduced condition, solid pig iron or the like, there is introduced into the melting heat from below a charge-accepting receptacle by means of burners the carbon content within the molten bath is adjusted by a sub-stoichiometric combustion of hydrocarbon. Addition of any coal to the charged material is avoided. By reducing the oxygen flow, in particular by performing the combustion with approximately 0.9-times of the stoichiometric amount of oxygen, and by optionally adding slag formers, the aggressivity of the slag in relation to the furance lining is simultaneously reduced.
