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.

The process is carried out in this vessel. Editions de La Revue de MetallurgieNanterre; Careers and apprenticeships Equal opportunities Vacancies Apprenticeships.
The plant had achieved fechnology production rate of 80 tons of hot metal per hour in early with a coal rate of kg per ton of hot metal.
The highly responsive nature of the process means that it converts iron ore, coal and flux to metal, slag and energy almost instantaneously. Regrettably, indication of copyright fee is not available. Construction of the HRDF with a design capacity oftons per annum, commenced in The projected improvements hisnelt the process are as follows.
Construction of the plant was started in January The process allows the use of non coking coal and iron ore fines with significant impurities. Slag is formed by fluxing the gangue in the iron ore and ash in the coal with lime and dolomite. Hot metal is tapped continuously through an open forehearth and is free of slag.
This reduction reaction produces iron Fe and carbon monoxide CO. HIsmelt, the future in ironmaking technology English. This operating flexibility maximizes productivity, as it is easy to maintain a steady state operating window. Course reserves Setting up a course reserve Form for setting up a course reserve.
Limit the search to the library catalogue. 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.
If BF is present then these technologies are the future. For further questions please contact our Hismept customer service. It is cleaned, cooled and used as a fuel and for power generation. These process capabilities allow for raw material feed rates to be changed very efficiently without affecting product quality. The process uses high velocity injection of coal and ore into the melt through downwardly angled water cooled injection texhnology. The SSPP operated from to and proved the viability of the technology.
The byproduct of the process is slag and the off gas. Located in Kwinana, Western Australia, the merchant pig iron facility was designed and engineered with a 6 meter hearth diameter SRV.
The core of the HIsmelt process is the smelt reduction hisemlt SRV which has a refractory lined hearth and water cooled upper shell.
HRDF vertical smelt reduction vessel was commissioned in the first half of and operated through to May Leave a Reply Cancel reply Your email address will not be published. The next stage for HIsmelt is commercialization by scaling up from a 2. The main improvements incorporated into the design included a stationary vertical tecbnology, 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.
Unlike blast furnaces, the HIsmelt process can be started, stopped or idled with ease. To overcome this deficiency a design was developed for water cooled vertical vessel. HIsmelt is short for high intensity smelting. This stage of operation confirmed that the process was ready to be scaled up to level of a commercial plant.
