FREMGANGSMAADE VED OG AGGREGAT TIL IFYLDNING AF EN KUPOLOVN

摘要

An improved charging process for an enclosure for melting materials such as blast furnace slags or basaltic glasses. The supply of combustive gas is carried out nonuniformly in order to create a gas circulation velocity gradient in the section of the cupola corresponding to the level of the tap hole, with the lowest circulation velocities meeting in the vicinity of the tap hole.
