There is no doubt that the technology of the blast furnace/basic oxygen (BF/BOF) route has improved steelmaking efficiency, productivity, and product quality compared to the open-hearth furnace. However, the direct reduced iron/electric arc furnace (DRI/EAF) route is a better option for North Africa and the Middle East-North Africa (MENA) region.

Under the same condition, the reduction rates of hydrogen and carbon monoxide gases are quite different. This process results in high porosity product, and for this reason, the product has another name called sponge iron. In this paper, the feasibility of producing direct reduced iron using water hydrogen instead of reducing gas was investigated.
Sep 05, 2019 Scrap-fed electric arc furnace (EAF) steelmaking is on a growth trajectory around the world, according to presenters at the 4 th Steel Scrap, Billet & DRI Trade Summit, hosted by SteelMint in Bangkok in late August.. In the first two decades of this century, China soared to become by far the world’s largest steel producer, relying largely on the iron ore-fed basic oxygen furnace (BOF) process.
Much of that new capacity, they noted, is coming in the form of scrap-fed electric arc furnace (EAF) or induction furnace production. Sanjoy Ghosh, senior manager of supply chain management at Bangladesh-based steelmaker BSRM , said the “40 active mills” producing steel in his nation imported 19 percent more ferrous scrap in the first half ...

Sponge Iron Production Process Arij Trading. This process is one of the oldest direct reduction methods and the idea of its structure is based on a horizontal cement kiln. In this method, heat coal (as a reducing agent) is mixed with iron ore and sponge iron is produced in a horizontal furnace.get price
Adaptation to Electric Arc Furnace to Drive the Direct Reduced iron (DRI) Market. As per a report available on XploreMR, the global Direct Reduced Iron (DRI) market is expected to scale new heights between 2020 and 2030. The Direct Reduced iron (DRI) market is being driven by the fact that steel manufacturers are going for a paradigm shift.
Direct reduced iron Wikipedia. Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 ...
