摘要

ROCKWOOL INTERNATIONAL A/S METHOD OF PRODUCING MOLTEN STONE MATERIAL IN A CUPOLA FURNACE Method of producing a melt from rock materials in a cupola furnace which materials are charged as uniformlyshaped briquettes together with coke. In order to recue the content of CO in the exhaust and to increase the metling capacity of the furnace, the flow of combustion air related to the cross-section of the furance is at least 60 Nm3/ m2 minute, and the briquettes having such a shape that a porosity in the combustion zone is more than 0.45.
