Effect of Hydrogen Concentration in Reducing Gas on …

7) Increase in the hydrogen concentration leads to a decrease in the shaft region temperature of BF. Therefore, higher reducibility of iron ore burden at lower temperature is required under higher hydrogen condition. Iron ore sinter, pellet, and lump ore are typical iron burdens of BF, and especially sinter is major one in East Asian countries.

Enrichment of Phosphorus from Iron Ore to Dicalcium ...

Abstract. Due to the low quality of available iron ore, it is necessary to develop a new technology to produce high quality steel from ore containing a high concentration of phosphorous. In this study, we propose a new process for producing low-P steel by concentrating P in the dicalcium silicate phase through a partial reduction process.
