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

Analysis of the Coke Particle Size Distribution and Porosity of Deadman Based on Blast Furnace Hearth Dissection

“…2) The hot metal quality, draining conditions of liquid phases, the campaign life and the blast furnace operation are determined by the deadman permeability and its state (sitting or floating). [1][2][3][4][5] The permeability of the deadman is directly related to the coke size distribution and its porosity. Therefore, it is important to study the coke particle size distribution and deadman porosity for understanding the blast furnace hearth performance.…”

A Visual PCI Blockage Detection in Blast Furnace Raceway

“…In fact, the campaign life and hot metal quality of blast furnace is directly influenced by the working condition of PCI. 2) During PCI blockage the pulverized coal injected to the tuyere can be discontinuous and uniformity, which causing local inhomogeneous permeability of the burden. To prevent the above situation happening, it is crucial to obtain a more reliable PCI blockage detection.…”

Microstructure and Phase of Carbon Brick and Protective Layer of a 2800 m³ Industrial Blast Furnace Hearth

“…1) The performances of carbon brick in blast furnace hearth have been widely studied. [1][2][3][4][5][6][7][8][9][10][11][12] These studies indicated that the peripheral flow of molten iron, dissolution of molten iron, attack of zinc and alkalis, thermal stress and fluid induced shear stress are the reasons for the corrosion of carbon brick. With the deterioration of raw materials and fuels, the blast furnace is facing great challenges.…”
