Reduction in specific energy requirements through optimization of charge in Hismelt(Ironmaking) Process Presented by Mainak Saha. ABSTRACT. Direct smelting of iron ore is an alternative process for pig iron production that is currently coming of age. The. HIsmelt Direct. The China HIsmelt plant was commissioned and operated in , after about But sintering and coking is a high pollution emission process.

It is cleaned, cooled and used as a fuel and for power generation. Hence this process has flexibility to use high phosphorus containing ores. Your email address will procesz be published. Slag can be granulated or directed into pits for further processing.

HIsarna ironmaking process – Wikipedia

Smelting Bloomery produces sponge iron Blast furnace produces pig iron Cold blast Hot blast Anthracite iron Direct reduced iron. This reduction reaction produces iron Fe and carbon monoxide CO. The process allows the use of non coking coal and iron ore fines with significant impurities. Retrieved from ” https: This hsmelt was last edited on 1 Decemberhismlet Any other technology to reach the level of BF will take a lot of time.


Annealing Low hydrogen Short circuit. Designed by Elegant Themes Powered by WordPress.

hismept The main product of the process is hot metal. This is done through large amounts of liquid splash moving between the two regions.

HIsarna is considered one of the most promising developments in reducing CO 2 emissions from the steel industry. Design and engineering for the vertical SRV Fig 1 was completed in The core of the HIsmelt process is the smelt reduction vessel SRV which has a refractory lined hearth and water cooled upper shell.

But some iron making technologies like finex, HIsmelt and HIsarna are technologically sound and have potential to have better techno-economics. Once there are successful operating references available for these technologies then all the future installations will be of these technology based iron making units. Cold commissioning commenced in the second half of while the hot husmelt was carried out in second quarter Donate Grateful for your donation!

At that time the desire was mostly a cost-cutting measure in order to make the process cheaper in trying economic times.

Low hydrogen Short circuit. Bessemer process Open hearth furnace Electric arc furnace Basic oxygen process. Blast furnace process is no doubt proven route globally.

However they need support of some dedicated entreprenuers to prove to the world that they are better technologies. These process capabilities allow for raw material feed rates to be changed very efficiently without affecting product quality.


HIsmelt process of Ironmaking |

The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron or hot metal.

From Wikipedia, the free encyclopedia. In the traditional process one cannot use powdered coal alone since the strength of the coke is required to support the burden. Schematic of the HIsarna process Rio Tinto [8].

Posted by Satyendra on Himelt 2, in Technical 2 comments. Slag is formed by fluxing the gangue in the iron ore and ash in the coal with lime and dolomite.

HIsarna ironmaking process

In November it was announced that a large scale HIsarna pilot facility would be built at the Tata Steel site in JamshedpurIndia[25] [26] but that the site in IJmuiden would still be a potential location for further industrial implementation of the technology. The refractory hearth contains the molten iron bath and liquid slag. The plant had rpocess a production rate of 80 tons of hot metal per hour in early with a coal rate hismeelt kg per ton of hot metal.
