摘要
ENERGIRON is the Direct Reduction innovative technology,jointly developed by Danieli and Tenova HYL alliance,that provides an extremely productive and flexible process,combined with high energy efficiency and very low environmental impact.It finally results in a DRI characterized by a lower cost,highest quality and the uniquely stable characteristic,which makes it a product safely transportable avoiding briquetting cost.In DRI-based integrated minimills,the use of the HYTEMP(R) system allows the delivery of Hot DRI directly to the EAF,thus further reducing electric energy consumption and tap-to-tap time.ENERGIRON plants are competitive even in those areas where Natural Gas is not economically convenient,as they can be designed to use also Coke Oven Gas ( COG) and Coal Gasification Gas ( SYNGAS),or a mix of them.among others,as reducing media.Moreover the raw material can be fed in the form which is preferably available in each specific plant site: from 1000% iron ore pellet in a wide range of sizes,up t0 1000% lump ore,or in a chosen mixture of both the forms.ENERGIRON Zero-Reformer ( ZR) technology is a major step in simplifying the DR process,reducing CAPEX and OPEX,with the elimination of the reformer and improving the availability of the plant.In ENERGIRON ZR technology,natural gas reforming is performed inside the reactor,taking advantage of the DRI as reforming catalyst.
