Abstract
Reducing gases at a temperature of at least 800 DEG C. are withdrawn from a blast furnace, which is otherwise operated in the normal manner for the production of pigiron from ore, and used to effect the reduction of ore to spongy iron. Specifications 9463/98 and 9464/98, [both in Class 72, Iron &c.], are referred to.
