Clean Production is the best method for iron-steel making industry to eliminate pollution thoroughly. In order to achieve this object

smelting reduction technology should play the key role. Furthermore

process integration method can be used to solve the problem of residual gas utilization by integrating smelting reduction process with direct reduced iron unit

gasoline

methanol or dimethyl ether synthesis unit

etc. A new smelting reduction process has been proposed which can be constructed on the present plant site. Since this process can directly treat the lump coal and iron ore fines

it reduces st6ps necessary in traditional blast furnace process and Corex smelting reduction process.
