一种新的炼铁工艺印度贾姆谢德布尔市的塔塔钢公司研究出一种新的炼铁工艺。该工艺包括将空气转化为含有煤粉的还原性气体，并利用这种气体将铁矿石还原为方铁体。然后将该还原铁在硫态化床上，以低灰分、燃烧率达１００％的洗精煤使其熔融。还原过程吨铁水需高质洗精煤３... A New Ironmaking Process Tata Steel, in Jamshedpur, India, has developed a new ironmaking process. The process involves converting air to a reducing gas containing pulverized coal and using this gas to reduce iron ore to ferrite. The reduced iron is then melted using clean coal having a low ash content and a burn rate of 100% on a sulfurized bed. Reduction process tons of hot metal needs high quality clean coal 3 ...
