Abstract: A stable skull layer formed on the inner surface of the hearth could effectively protect the lining and extend blast furnace campaign life. This is the first comprehensive work of using integrated heat transfer, fluid flow dynamics and solidification numerical simulation to investigate skull formation phenomena in a blast furnace hearth. The impact of hearth design and furnace operation parameters on skull formation is examined, including lining property and structure, cooling water temperature and flow rate, … Show more

“…The rotational speed of the pedestal was 1 rpm, corresponding to a linear velocity of hot metal in the sleeve vicinity of about 1.5 mm s −1 . It should be noted that in a normal BF hearth operation the hot metal velocity varies within the range of 0.1–0.4 mm s −1 except for regions near the taphole . As depicted in the left part of Figure , the refractory sleeves were identical in those two experiments.…”

“…A number of studies have investigated the hearth erosion of the BF, but the information on the composition and the microstructure of lumped skull lining material are still very limited. [7][8][9][10][11][12][13][14][15][16] An improved understanding of the skull formation and the wear…”

“…Other modeling included simulation of the process of skull formation within the furnace hearth, including the processes of solidification, flow, and heat transfer, with parametric studies on the hot metal temperature, production rate, and cast practices, among other operating conditions . Analyses of hearth liquid level during tapping were also conducted to explore the release of gas from the tap hole due to pressure differentials.…”
