摘　　要：以市售w（Cr2O3）=26.02%的电熔再结合镁铬砖和自制预合成的不同FeO含量的铁浴式熔融还原渣为研究对象,采用旋转圆柱法,研究了铁浴式熔融还原渣中FeO含量（其质量分数分别为0、5%、10%和15%）和试验温度（1 450、1 500、1 550和1 600℃）对镁铬砖试样侵蚀量、显微结构的影响。结果表明：（1）不含FeO的渣对镁铬试样的侵蚀量大于FeO含量（w）为5%的渣,渣中FeO含量（w）为5%~15%时,随着FeO含量的增加,镁铬试样的侵蚀量增大,侵蚀加剧;（2）温度是影响镁铬材料抗渣性能的重要因素之一,温度提高,熔融还原渣对耐火材料的侵蚀加剧。Effects of FeO content（mass percent is 0,5%,10%,and 15%,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 re-bonded magnesia-chrome brick with 26.02% 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.
