主 题：MgO-based refractory Corrosion Basic slag Electromagnetic field
摘 要：To illuminate the corrosion behavior of MgO-based refractories under electromagnetic field(EMF),herein,the slag corrosion and penetration resistance of MgO–MgAl_(2)O_(4),MgO–CaO,and MgO–C refractories were investigated using the rotary immersion slag resistance test at 1873 K for 1 *** results showed that the order of the good slag resistance of as-tested refractories was MgO–CMgO–CaOMgO–MgAl_(2)O_(4).The EMF accelerated the corrosion and penetration of slag to the refractories,which caused the molten slag to be easier into the refractories by natural convection and Marangoni *** addition,the MgO–C refractories did not show an overwhelming advantage in slag resistance because EMF impeded the formation of the dense protection ***,in view of the present results,the MgO–C refractories are still the most promising slag line material for refining furnace among MgO–MgAl_(2)O_(4),MgO–CaO,and MgO–C refractories.
