Effects of Temperature, Refractory Composition and Mass Transfer Rate on Corrosion Rate of Al₂O₃–SiO₂ System Bricks into CaO–SiO₂–Al₂O₃–MgO Slag

Influence of TiO2 on the Viscosity of a High Alumina Slag and on Carbon Brick Corrosion

“…Um et al investigated the corrosion behavior of MgO–C brick in CaO–SiO 2 –Al 2 O 3 –MnO slags, indicating that the corrosion of refractory increased with the addition of MnO. Hino et al investigated the corrosion rate of Al 2 O 3 –SiO 2 bricks into CaO–SiO 2 –MgO–Al 2 O 3 slags, and the corrosion rate decreased with the Al 2 O 3 content in the brick increased or temperature decreased. The corrosion mechanism of refractories in contact with different slags has been studied extensively.…”

Behavior and Kinetic Mechanism Analysis of Dissolution of Iron Ore Particles in HIsmelt Process Based on High-temperature Confocal Microscopy

“…In addition, the study of the dissolution process has applications in many fields. In the study of steel materials, many studies have reported the dissolution behavior of inclusions or refractory materials in metallurgical slag for steel purity [16][17][18][19][20] or prevention of refractory erosion [21][22][23] . Different types of high-temperature confocal microscopes were used in these studies to make in situ observations of the dissolution mechanism of oxides [16][17][18][19][20][21][22][23][24][25][26] .…”

Effects of Sulfur and Titanium Interaction in Molten Pig Iron on Erosion of Carbon Brick

“…The service life of blast furnace (BF) is largely determined by the erosion of carbon brick, 1,2) the erosion is inevitable due to the direct contact between carbon-undersaturated molten pig iron and carbon brick. 3,4) The erosion rate is affected by temperature, element content, the flow of molten pig iron et al, 5) to reduce the erosion rate of carbon brick has become the primary target to prolong the service life of BF.…”
