PROCESS AND DEVICE FOR SMELTING METALS IN CUPOLA FURNACES RUN WITHOUT COKE

摘要

The invention relates to a process and device for smelting in cupola furnaces run without coke. According to the invention, substances are injected into the space between the smelting grate (4) and the burners (7) located below it which improve the quality of the smelting product and keep it constant. The devices used for injection into the space between the grate (4) and the burners (7) are preferably lances (15) pointing obliquely downwards and designed so that the emergent stream is directed upwards.
