Research Status and Development Trend of Numerical Simulation on Blast Furnace Lining Erosion

Analysis of Blast Furnace Hearth Sidewall Erosion and Protective Layer Formation

“…3,4) Many studies on the relationship between inner hearth condition and BF operating conditions, such as heat load, molten iron flow, the lower boundary level and permeability distribution of deadman in hearth have been carried out by using numerical simulation method. 5,6) Considering the complexity and variety of phenomena and reactions occurring in the BF, our current knowledge of the inner condition of the BF is still limited. The inner erosion condition of BF can only be observed by the dissection of the furnace after blow-out.…”

Dissolution Mechanism of Carbon Brick into Molten Iron

“…1,2) The hearth sidewall which is considered as the key area of BF has attracted more and more concerns. 3,4) The direct contact between carbon refractory and carbon-unsaturated molten iron is regarded as the main reason for the hearth sidewall erosion. The erosion is inevitable due to the carbon is easily dissolved into molten iron.…”

Sensitive Influence of Floating State of Blast Furnace Deadman on Molten Iron Flow and Hearth Erosion

“…Many authors have studied the large coke free zone from the deadman to the wall. 20,23,24) In this paper, the authors aim to study the molten iron flow and erosion at different floating heights of deadman. Therefore, it is assumed that there is a coke free zone near the hearth wall and the thickness of the zone is 0.1 m, which is shown in Fig.…”
