摘要

The present invention provides a method of ironmaking using full-oxygen hydrogen-rich gas which comprises hot transferring and hot charging the high-temperature coke, sinter and pellet into the ironmaking furnace (3) through transferring and charging device, and injecting oxygen and hydrogen-rich combustible gas at a predetermined temperature into the ironmaking furnace (3) through the oxygen tuyere and the gas tuyere disposed at the ironmaking furnace (3), respectively. It also provides an apparatus for ironmaking using full-oxygen hydrogen-rich gas which comprises a raw material system, a furnace roof gas system, a coke oven gas injecting system, a dust injecting system, a slag dry-granulation and residual heat recovering system and an oxygen system (11). Additionally, it further provides an apparatus and method for hot transferring and hot charging of ironmaking raw material.
