HIsmelt process of Ironmaking
High phosphorus iron ore fines have no adverse effect on the phosphorus reporting to the hot metal. The process allows the use of non coking hsmelt and iron ore fines with significant impurities.
Designed by Elegant Themes Powered by WordPress. The new plant is expected to be commissioned in Hot metal is tapped continuously through an open forehearth and is free of slag.
Electronic books The e-book database EBC. It is envisaged that commercial plants will techology significant levels of reverts which will reduce operating costs. HIsmelt, die Zukunft tecnology Technologie der Roheisenherstellung. The main product of the process is hot metal. This reduction reaction produces iron Fe and carbon monoxide CO. Since the slag is batch tapped through a slag notch, the hot metal is slag free.
Scientific Data Management Research Staff. This operating flexibility maximizes productivity, as it is easy to maintain a steady state operating window. Injected iron ore fines are injected deep into the yechnology where they are reduced instantly on contact with carbon dissolved in the bath for smelting to take place. Posted by Satyendra on Jul 2, in Technical 2 comments. The projected improvements from the process are as follows.
This combustion occurs in the relatively oxidizing region in the upper section of the SRV. Regrettably, indication of copyright fee is not available. The main product of the process is liquid iron or hot metal which can be used in steel melting shop or cast in pig casting machine to produce pig iron. The next stage for HIsmelt is hiamelt by scaling up from a 2. Reaction gas CO and coal devolatilization products which are generated from deep within the bath form a fountain of mostly slag and some metal.
Ask for availability for Tecnnology. Unlike blast furnaces, the HIsmelt process can be started, stopped or idled with ease. The partnership seeks to finalize the development of HIsmelt technology and to work together to further improve the technology to higher levels of environmental and economic techonlogy.
HIsmelt- plant goes to China | Steel Times International
This stage of operation confirmed that the process was ready to be scaled up to level of a commercial plant. For LUH campus users we will be happy to check if free access is available for you. Byproducts of the process are slag rechnology off gas. Cold commissioning commenced in the second half of while the hot commissioning was carried out in second quarter It is cleaned, cooled and used as a fuel and for power generation.
Typical temperature of hot metal is around — deg C and typical composition of the hot metal is as follows:.
Advanced Search Watchlist Search history Search help. The plant had achieved a production rate of 80 tons of hot metal per hour in early with a coal rate of kg per ton of hot metal. The HIsmelt process smelts iron ore and coal in a water cooled refractory lined vertical vessel to produce hot metal suitable as feed to BOF’s and EAF’s. HIsmelt process is highly flexible. Located in Kwinana, Western Australia, the merchant pig iron facility was designed and engineered with a 6 meter hearth diameter Hismrlt.
Once there are successful operating references available for these technologies then all the future installations will be of these technology based iron making units.
Liquid slag and metal splash acts as a carrier of the heat. However they need support of some dedicated entreprenuers to prove to the world that they are better technologies.
Editions de La Revue de MetallurgieNanterre; A range of iron feeds including high phosphorus iron ore fines and steel plant wastes in conjunction with low and high volatile coals were hismflt smelted at the Kwinana pilot plant over an hour techonlogy period. Trials were conducted in a 60 tons OBM converter to demonstrate the fundamentals of the smelt reduction process. The refractory hearth contains the molten iron bath and liquid slag.
The process has been developed to treat iron ore fines with minimum pretreatment, making the process more flexible in terms of the quality of iron ore it can treat. To develop the HIsmelt technology further, Rio Tinto has signed a development agreement with a Chinese steelmaker.
