Abstract

A shaft furnace such as a blast furnace or a hot blast basic cupola furnace is restored to or towards its normal operating temperature, e.g. 1000-1400 DEG F., after its temperature has been reduced below this because of slips and scaffolding by adding raw petroleum coke, e.g. containing between 8% and 15% volatile content and less than 1% ash content and preferably having a particle size between 1/8 inch and 5 inches average dimension, to the charge, e.g. ore, coke and limestone, already contained in the furnace. Specification 999,352 is referred to.
