| Abstract: | An environmental-friendly patching brick for basic oxygen furnace(BOF) was prepared using sintered magnesia(w(MgO)>92.21%) and waste MgO-C material(oil contaminated,w(MgO)=84.34%) as starting materials,modified asphalt as flow agent,a little sulphur as flow aid,and calcium lignosulphonate solution as binder.The on-site test was carried out.The results show that the patching bricks perform good soften ability at high temperatures,short sintering time,energy saving and environmental protection. |
