As a mainstream of modern non-blast furnace ironmaking method, direct reduction of shaft furnaces was rapidly developed at present, but in recent years it has been ebb and flowed down by many factors such as energy and scrap situation, etc. The grim reality has forced shaft furnace reduction to seek new The direction of development.Some of the new furnace reduction technology adapted to the energy structure and economic situation are showing their prospects of development.How to establish the guidelines for the development of shaft furnace reduction in this situation in our country, Is a question worth serious discussion. First, the direct reduction of foreign shaft furnace and its hair
