  • Climate Change in Iron and Steelmaking Review 02 Iron

    At the steelmaking site, iron ore is converted to metallic iron by reduction of the iron ore pellets with coke in a blast furnace. The iron oxide and carbon then react to form CO and CO 2 gases, as well as metallic iron. Now in liquid form, the iron is further processed before a semi-finished steel product is cast.

    Dec 10, 2012 Investment and operational costs of the process are reported to be $344.4 and $183.1 per ton of steel, based on a scrap cost of $120/t-scrap (US DOE, 2003. p. 4/4.) Commercial. Waste Heat Recovery for Rotary Kiln Direct Reduction. The coal consumption is about 800 kg/t DRI.

  • Direct Reduced Iron Industrial Efficiency Technology

    Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.

  • Direct Reduced Iron and its Production Processes Page 10

    Mar 16, 2013 These reactors are (i) rotary kiln, (ii) shaft furnace, (iii) fluidized bed reactor, and (iv) rotary hearth furnace. Rotary kiln is the most popular reactor for the coal based process. The principle of the direct reduction of iron ore is shown in Fig 1.

  • Heat and Mass Transfer in Reduction Zone of Sponge Iron

    Numerical prediction is performed on reduction zone of iron ore reactor which is a part of counter current gas-solid reactor for producing sponge iron. The aim of the present study is to investigate the effect of reduction gas composition and temperature on quality and capacity of sponge iron products through mathematical modeling arrangement and simulation.

  • Influence of direct reduced iron on the energy balance of

    Oct 01, 2011 An alternative production route of steel is based on the reduction of iron ore to direct reduced iron, DRI, with reformed gas enriched in carbon monoxide, CO, and hydrogen, H 2.Reformer gas is produced from natural gas, biomass or gasified coal. 71.3 Mio tonnes DRI were produced in 2010 with continuously increasing trend during the last three decades despite increasing energy costs of

  • Integrated minimill for iron and steel making Techint

    Rotary kiln 116 transports the hot DRI 110 to EAF 118. Rotary kiln 116 is refractory lined and insulated to reduce heat loss from DRI. Since rotary kiln 116 does not process the DRI, it may be designed to be any desired length and inclination to match the distance between DRR 110 and EAF 118 and to suit the layout of integrated mini-mill 100.

  • Remove Rotary Kiln

    Rotary Kiln In Magneticreduction Roasting. Magneticreduction roasting is a process in which nonmagnetic ore is converted by the action of reducing gases to a state in which subsequent magnetic separation can achieve the best balance between recovery and grade the principal characteristics of the rotary kiln method of magneticreduction roasting are complete processing and heat exchange within

  • 11 Current status of the iron and steelmaking industry

    Rotary kilns (such as the SL/ RN) typically have capacities ranging between 150000 and 200000 tpa. These processes charges lump ore, pellets and fines (1.42 t/t HB), fine coal (0.85 t/t HBI) and limestone and dolomite (mainly for sulphur removal) into an inclined kiln that rotates at speeds less than 1rpm. The ore is dried, pre-heated
