【摘要】 针对传统的竖炉海绵铁生产工艺法，提出了“以焦炉煤气代替天然气非预转化竖炉法生产海绵铁”的新观点。实践证明：此工艺不仅技术上可行，而且ＣＨ４在竖炉里可以得到转化，完全可以生产出合格的海绵铁。更多还原

【Abstract】 In view of traditional shaft furnace process of sponge iron,the new viewpoint was put forward,in which sponge iron could be produced by non preinverting shaft furnace with coke oven gas other than natural gas.It has been proved by practice:the process not only possesses possibility in technology,but also CH 4 can be inverted in shaft furnace,therefore,qualified sponge iron can be produced undoubtedly.更多还原
