Several rotary slag erosion tests were carried out as a part of study on refractories for desiliconization, dephosphorization, and flux injection lance. Al_2O_3-SiC-C bricks are the most suitable refractories for desiliconization, and low silica spinel-C bricks are the most suitable for dephosphorization. By considering the cost, however, the former are better than the latter in performance. High alumina castable refractories containing 70 to 90% Al_2O_3 are suitable for lining of flux injection lance. Since lance performance is influenced by deformation, and vertical and horizontal cracks in addition to erosion, strengthening of the inner pipe and proper expansion clearance between the inner pipe and castable refractory are necessary.
