Hydrogen-enrich iron making process is certainly to be an effective method to reduce greenhouse gases emission.However,the effect of hydrogen addition on the low temperature metallurgical property of sinter is still unclear.A detailed investigation was performed on the above topic.The results are as follows.When CO is partially replaced by H2,the RDI〈3.15（RDI〈2.8） of sinter decreases with the increase of the H2 content;when the content of H2 increases,the CO,CO2 and N2 decrease proportionally,in this case,RDI〈3.15（RDI〈2.8） of sinter increases with the increase of H2 content;the value of RDI〈3.15（RDI〈2.8） basically depends on the reduction index（Ri）.The experimental data of RDI〈2.8 based on Japanese industrial standard（JIS） are a little higher than the data of RDI〈3.15 based on Chinese industrial standard（CIS） in the same condition.In addition,for part of CO is replaced by H2：RDI〈2.8=3.38394＋1.1585 RDI〈3.15;for other gases,except H2,are decreased proportionally：RDI〈2.8=17.39678＋0.42922 RDI〈3.15
