| Abstract: | Dericiase-spinel samples are made from electrofused magnesia clinker and the presynthesized electrofused at clinker and then fired at high tempeatures.The effect of little chrome on the thermal shock resistance and slag resistance of the samples have been studied.The tests show that the properties can be largely increased.The periclase-spinel system reftactories were tested by corrosion from the high CaO converter slag by the crucible method,nd the effects of Cr_2O_3 on the slag resistance of peciase-spinel tefractories are analyzed by the methods of XRD,SEM,EDAX and mineral phase analysis. |
