| Abstract: | The moulded blanks are pressed by blending with iron scale as raw material,adding 2%accelerant for reducing and 1%binding agent.Then the directly reduced iron is manufactured by retort process with external heat method with braize of 29%of weight of iron scale as reducing agent,desulfurizing agent of 6%of weight of iron scale,temperature of reduction of 1280℃and soaking time of 8 h,which could replace steel scrap in steel-melting with converters. |
