据俄刊《冶金工作者》报道加拿大冶金专家发明了一种高喷煤量氧气炼铁新工艺。该工艺仍用传统的高炉作为反应容器 ,通过风口喷入非炼焦煤可达到 3 0 0kg t以上 ,使焦比降至 2 0 0kg t以下 ,接近维持炉内料柱必要透气性的最少焦炭用量值 ,获得了以煤代焦、煤为主而改变了炼铁工 According to the Russian issue of “Metallurgical Workers,” Canadian metallurgical experts have invented a new technology for high-oxygen coal-fired ironmaking. The process is still using the traditional blast furnace as a reaction vessel, through the tuyere injection of non-coking coal can reach more than 300kg t, so that the coke ratio to less than 200kg t, close to maintain the furnace gas column material required minimum permeability of coke Value, obtained by coal coke, coal-based and changed the ironworks
