sponge iron production corex process in venezuela

Technology and Processes Behind Steel Production

Sponge iron, such as direct reduced iron (DRI) and hot briquetted iron (HBI), produced from iron ore in direct reduction plants is converted to crude steel in electric arc furnaces. Steel is 100 percent recyclable, so crude steel is also produced by recycling steel scrap in electric arc furnaces. Get price

The Energy Blog: Cleaner Iron Production with Corex

2006/11/24A special manufacturing process is making the production of iron much more environmentally friendly. The outstanding feature of the "Corex process" is that it uses conventional coal instead of coking coal, the customary ingredient. Siemens is currently building the world's largest Corex-based plant in China. Scheduled to begin operation in late 2007, this steel mill requires no coking Get price

Cleaner Iron Production with Corex Process

In a separate process in a melter gasifier, these vile smelling, and highly toxic, compounds are almost completely combined in sponge iron, aggregates, and slag. In conventional pig iron production at iron works, coking coal is first mixed with charge consisting of pellets, sinter and lump ore, and then the mixture is put into a blast furnace. Get price

Sponge Iron

Unlike the iron sponge process, the SulfaTreat material is non-pyrophoric and has a higher capacity than iron sponge on a volumetric or mass basis. In the process, the inlet gas stream enters the unit through a small inlet separator to separate out any entrained liquid, salt water, and any liquid hydrocarbon in the gas stream. Get price

Different Steel Production Proceses

in this process the sponge iron is remelted, melting scrap is main inputs to produce finished steel. It uses 400-500 kWh/ton of electricity. ISPAT,ESSAR and the Jindal group uses this technology. COREX or Cipcor Process: it is an advance process of making Get price

Hot metal and crude steel production

The sponge iron is mainly used for steel production in electric arc furnaces. Two steps are required with the smelting reduction method. First the ore is reduced to sponge iron and this is then converted to a blast-furnace-like form of hot metal through the use of coal and oxygen. Get price

Recycling of steel plant mill scale via iron ore pelletisation

2013/11/29Mill scale is an iron oxide waste generated during steelmaking, casting and rolling. Total generation of mill scale at JSWSL is around 150 t/day and contains 60–70%FeO and 30–35%Fe 2 O 3 . To recover the iron, the mill scale must be smelted in a blast furnace or other reduction furnace; however, it is usually too fine to use without previous agglomeration such as via pellet or sinter mix.
