Since Ansteel implement the strategy of low cost to run, the system of ironmaking around company’s requirements optimized the structure of sinter blending, optimized the burden structure of blast furnace, and improved sinter and lump ore’s ratio imported , reduced the proportion of expensive pellets imported that into the furnace. At the same time we have done a good of job in other areas of concentrate. With changes of the burden structure. we have taken a series of technical measures to maintain a long-term stability of the blast furnace, and have achieved low-cost ironmaking running.
