Effects of FeO content(0,5%,10%,and 15% in mass,respectively) in lab-synthesized smelting reduction slag with iron bath and test temperature( 1 450,1 500,1 550,and 1 600 ℃) on corrosion amount and microstructure of fused rebonded magnesia- chrome brick with 26. 02 mass% of Cr2O3 were researched by rotary cylinder method. The results show that:(1) the corrosion amount of magnesia- chrome brick by slag without FeO is higher than that by the slag with 5% FeO,and the corrosion amount increases when FeO content increases from 5% to 15%;(2) the test temperature is one of the important factors affecting the slag corrosion resistance of magnesia- chrome brick,and the corrosion of smelting reduction slag to brick increases with the temperature rising.
