Study on High Temperature Smelting Hydrogen Metallurgy

It was studied by thermodynamics calculation in different patterns that the feasibility of decreasing the heat burden of melting furnace by blowing hydrogen to replace C as reducing agent in this paper.The results showed that the heat burden of melting furnace can't be reduced by blowing hydrogen for the current smelting reduction processes,but it can be realized by modifying the current smelting reduction processes by reducing the quantity of coal injection and increasing the quantity of hydrogen injection to make the C:0 lessthan 1:1.Exclusive-hydrogen smelting reduction can realize green metallurgy,but it should be further developed.
