【摘要】 研究了温度、保温时间、粗铜的加入量和气氛等因素对镁铬耐火材料抗粗铜侵蚀性能的影响。结果表明 :随着侵蚀温度的升高 ,侵蚀保温时间的延长和粗铜加入量的增加 ,其渗透面积增大 ;气氛对粗铜渗透性影响较大 ,粗铜熔体中 [O]浓度越高 ,粗铜的渗透性越强。更多还原

【Abstract】 The attack of blister copper on magnesia-chrome refractories was studied in the laboratory.At the same time,the effects of temperature,holding time,atmosphere and addition of blister copper on corrosion resistance of magnesia-chrome refractories were discussed.The results show that,with the increases of temperature,holding time and addition of blister copper,the penetration areas of blister copper increase,and the effect of atmosphere was serious.更多还原
