The core of the HIsmelt process is the smelt reduction vessel (SRV) which To develop the HIsmelt technology further, Rio Tinto has signed a. HIsmelt is an iron making technology that has several advantages over using blast furnaces. These advantages and the process are described. HIsmelt is a breakthrough iron making technology that has attained full-scale commercial viability and is taking rapid strides in China where.

HIsmelt process of Ironmaking |
HIsmelt process is highly flexible. An 8m SRV with a hot metal production capacity in excess of 1. The main improvements incorporated into the design included a stationary vertical vessel, top injection of solids, a simplified hot air blast lance, a fore hearth for continuous tapping of metal and water cooled panels to overcome refractory wear problems.
The SSPP operated from to and proved the viability of the technology. Slag is formed by fluxing the gangue in the iron ore and ash in the coal with lime and dolomite.
HIsmelt- plant goes to China | Steel Times International
Smelting steel plant wastes improved productivity account of the pre-reduced iron feed and reduced coal consumption. For further questions please contact our TIB customer service. The main objective of the HRDF was to demonstrate the process and engineering scale up of the core plant and to provide operating data for commercial evaluation. But some iron making technologies like finex, HIsmelt and HIsarna are technologically sound and have potential to have better techno-economics.
The highly responsive nature of the process means that it converts iron ore, coal and flux to metal, slag and energy almost instantaneously. Scientific Data Management Research Staff. Course reserves Setting up a course reserve Form for tschnology up a course reserve.
Typical flow sheet of the process is shown in Fig 2 and the typical layout of the process is in Fig 3. It is cleaned, cooled and used as a fuel and for power generation.
HIsmelt process of Ironmaking
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. The next stage for HIsmelt is commercialization by scaling up from a 2. Hot metal is tapped continuously through an open technologyy and is free of slag. The byproduct of the process is slag and technoology off gas. Located in Kwinana, Western Australia, the merchant pig iron facility was designed and engineered with a 6 meter hearth diameter SRV.
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. Press and information Press releases Press Archives. Injected iron ore fines are injected deep into the bath where they are reduced instantly on contact with carbon dissolved in the bath for smelting to take place.
The projected improvements from the process are as follows. Careers and apprenticeships Equal opportunities Vacancies Apprenticeships.
The main product of the process is hot metal. Construction of the HRDF with a design capacity oftons per annum, commenced in The process is carried out in this vessel. Browse subjects Browse through journals Browse through conferences.

High phosphorus iron ore fines have no adverse effect on the phosphorus reporting to the hot metal. The process uses high velocity injection of coal and ore into the melt through downwardly angled water cooled injection lances. Reaction gas CO and coal devolatilization products which are generated from deep within the bath form a fountain of mostly slag and some metal.
This stage of operation confirmed that the process was ready to be scaled up to level of a commercial plant. Posted by Satyendra on Jul 2, in Technical 2 comments. HIsmelt, die Zukunft der Technologie der Roheisenherstellung. The core of the HIsmelt process is the smelt reduction vessel SRV which has a refractory lined hearth and water cooled upper shell.
