高喷煤氧气炼铁新工艺加拿大冶金专家发明的这种新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达吨铁３００ｋｇ以上，使焦比降到２００ｋｇ以下，接近维持炉内料柱必要透气性的最少焦炭用量值，获得了以煤代焦的重大进展。同时还把高炉的生产能力提高了１倍以... High-jet coal oxygen metallurgy new technology Canadian metallurgists invented this new process is still using the traditional blast furnace as a reaction vessel, injected through the tuyere of non-coking coal up to more than 300kg of iron, so that the coke ratio below 200kg, close to maintain the furnace The minimum amount of coke required for gas permeation within the column is a significant improvement on coal coke substitution. At the same time also increased the production capacity of blast furnace doubled ...
