- Abstract
The slag resistance of two kinds of natural bauxite clinker blocks and three kinds of homogenized bauxite clinker blocks was studied by cutting and static crucible inlaying at 1 500 °C for 6 h. The results show that the iron slag resistance of the natural bauxite clinkers is significantly better than that of the homogenization bauxite clinkers, which has no positive correlation with the AI203 content and the water absorption rate;for natural bauxite clinker with AI203 content more than 88 mass%, the water absorption rate determines the slag resistance homogenized bauxite clinker, the iron slag resistance increases with the increase of the AI203 content, has no correlation with the water absorption. According to SEM. it can be found that the difference of glass phase distribution is the main reason for the huge difference of the iron slag resistance between natural bauxite clinkers and homogeneous bauxite clinkers. Therefore, no matter the alumina content, homogenization bauxite clinkers are not suitable for the parts contacting with molten slag, such as iron runners.
