The Carbon Cost of Slag Production in the Blast Furnace A
The Carbon Cost of Slag Production in the Blast Furnace A Scientific Approach. The quality of raw materials (iron ore coal and coke) has a clear impact on the carbon emissions of the hot metal production in steel making. So far very little work has been done to measure and quantify this impact. In the iron and steel sector for example they would be found controlling the production process at a blast furnace or at steel furnace or the production of coils in a hot rolling environment. These processes are large scale operations involving a high level of responsibility.

Dead-Man Behavior in the Blast Furnace Hearth—A Brief Review
The blast furnace campaign length is today usually restricted by the hearth life which is strongly related to the drainage and behavior of the coke bed in the hearth usually referred to as the dead man. Because the hearth is inaccessible and the conditions are complex knowledge and understanding of the state of the dead man are still limited compared to other parts of the blast furnace process. enhancement of blast furnace functions summarizes our blast furnace operations historically and technologically and provides a view towards future blast furnace operation. 1.
