Effects of SiO₂ and Al₂O₃ Contents of Converter Slag on its Sticking to MgO-C Brick

Abstract:

Using ladle slag, ferrovanadium smelting slag as well as slagging materials as starting materials, the converter slags with SiO₂ contents of 11.3% to 2.6%, Al₂O₃ contents of 3.3% to 19.1% were prepared and some cylinder-shaped MgO-C samples were processed to fulfill slag sticking tests conducted at 1600°C in atmosphere furnace. The research results show that the amount of slag adhesion decreases with a reduction of SiO₂ content and an increase of Al₂O₃ content in slag, owing to larger viscosity and higher foam index of molten slag. To control the variations of SiO₂ and Al₂O₃ contents in converter slag is conducive to better slag splashing. Furthermore, the mechanism of SiO₂ and Al₂O3 contents of converter slag impacted on slag sticking to MgO-C brick has been further discussed.
