Analysis of the Deadman Features in Hearth Based on Blast
A large area of coke called deadman is formed in the low part of ironmaking blast furnace. The recognition of the deadman is significant to the evaluation of the performance for blast furnace. 1) In recent years with the increase of smelting intensity the molten iron flow brings much more heat into the hearth and therefore the hearth refractory is exposed to high temperature iron and
