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.
