DRI use in blast furnace - American Metal MarketAdvantages of HBI Use in BF's. • Use of HBI allows greater flexibility in BF production rates, allowing output to be increased during periods of increased hot metal demand. (vs. restarting an idled furnace). • HBI is easier to use than scrap in the materials handling system of the blast furnace. • Rule of thumb is that for each 10.Recycling of Ferrous Scrap from Incinerator Residue in Iron and .Ferrous scrap from incinerator residue from four sources has been evaluated for potential use in iron and steel making. These evaluations consisted of 42 induction furnace melts, nine laboratory electric furnace melts and a blast furnace test. The studies were conducted at the. National Steel Research Center and the Great.
The growing importance of steel scrap in China - McKinseyhas had limited amounts of obsolete (or postconsumer) scrap to use as a material in steel- making. However, as . based on basic oxygen furnace (BOF) technology to electric arc furnace (EAF) technology that relies more ... noted earlier, markets with excess blast furnace capacity such as China tend to favor hot metal over.the making of iron and steel - SEAISIThe electric arc furnace uses primarily electrical energy to supply heat to melt scrap steel, sponge iron, or mixtures of . furnace. However, if fine ore were to be used as feed to a blast furnace its powdery nature would restrict the passage of the blast air up through the furnace, limiting its permeability. The problem of using.
