直接還元鉄の電気炉溶解実績と熱間成型還元鉄の性状

抄録

The direct reduction process is now playing an important role, not only as a supplemental ironmaking procedure in the natural gas or coal producing regions of the world, but also as a technology to provide new iron source free of residual elements to iron and steelmakers, particularly those using electric arc furnace technology.
Continuous charging and slag forming operation of directly reduced iron in electric arc furnace can decrease tap to tap time and refractory wear and lowers electrode consumption.
Recentry, new technical improvements of the hot briquetted iron has been completed which is hardly reoxidized and pulverized during transportation and storage.
Commercial application of this research will permit further increase of market demand for the hot briquetted iron.
