Ironmaking in the digital age

Professor Bob Loo is the Director of the Centre for Ironmaking Materials Research (CIMR), which is a partnership between Newcastle Institute for Energy and Resources (NIER) and BHP Billiton.

Professor Bob LooA PhD graduate from the University of Oxford in the UK, Professor Loo's main area of expertise is the behaviour of iron ores in the ironmaking process. He has authored over 55 journal articles on which and how fundamental ore properties influence the efficiency of the blast furnace and sintering properties. He has also assisted BHP Billiton in the evaluation of new deposits, defining the specification of the ores from these deposits and their marketing to steel mills all over the world.

In 1998 Professor Loo's team received a Major Innovation Award for research and technical contributions in marketing, which resulted in an unprecedented demand for a new ore (Yandi) in the marketplace.  This ore, which was previously considered a problematic material and, hence, only used at low levels, is now a major component in most Asia Pacific ore blends. At the University of Newcastle, research on world iron ores, and the relationship between fundamental ore properties and performance in the ironmaking process continue to be Professor Loos' major activities and his work is fully funded by BHP Billiton.

Professor Loo has successfully supervised three BHP Billiton sponsored postgraduate research students. These include a PhD project at Zhejiang University which was aimed at building a mathematical model of the sintering process based on the fundamental knowledge acquired from research. Further work to improve and fine-tune the complex model is now being carried out at the University of Newcastle under a three-year BHP Billion funded agreement. The model is able to predict the performance of blends under a range of sintering conditions and is used by BHP Billiton to help understand the behaviour of new ores and ore blends, and provide performance data to help determine the value of an iron ore.

Since joining the University of Newcastle Professor Loo has also been successful in obtaining ARC grants. The first was a three-year Linkage grant with partner organisations BHP Billiton and Bluescope Steel, to examine the factors controlling sinter product size and strength. The ability to control these two parameters has a major influence on the economics of both the sintering and blast furnace operations. More recently, Professor Loo was part of the team involved in establishing an ARC Research Hub for Advanced Technologies for Australian Iron Ore. Professor Kevin Galvin (Priority Research Centre for Advanced Particle Processing and Transport) and Emeritus Professor Alan Roberts (Centre for Bulk Solids and Particulate Technologies, TUNRA Bulk Solids) are the other collaborators and BHP Billiton is the major partner organisation.

The Research Hub aims to develop fundamental knowledge in the areas of iron ore beneficiation, handling and end-use, which will be used to support the development of new separation and handling technologies to sustain and grow value in iron ore production and sales.

Iron ore sintering is the most popular process used to produce a suitable feed for the blast furnace. With changing iron ore supplies and composition, steel mills have to continually adjust the blended ore mix composition to the sinter plant. To help decision making in this area, and also obtain increased understanding of the process to allow improvements in sintering operations, laboratory-scale sinter pot tests are conducted. The use of a pot for routine testing and for research is discussed. When used as a research tool, the experimental approach used to simulate a plant will have to be modified to facilitate the interpretation of results. Airflow rate through a bed is a critical parameter and this paper highlights the important relationship between post- and pre-ignition airflow rates and also the effect of changing bed suction and coke level in the sinter mix.

The generation of sufficient melt of appropriate properties is essential for the transformation of a blended sinter mix bed into a bed composed of large discrete sinter particles. For a chosen sinter mix, melt properties are determined by the quantity of heat transferred from the moving flame front and the chemical properties of the bed. Temperature-time profiles from embedded thermocouples are used to assess the transferred heat. From considerations of melt initiation and solidification temperatures, a critical sintering reaction area in the profiles is defined. The area is about three times the flame front area as it includes high temperature regions outside the front. It represents the total amount of heat available to the material in the partially molten state. Reasonable correlations are obtained between this area and the tumble strength of the sinter product. Temperature-time profiles are quite variable and strong correlations cannot be expected.

The performance of a sinter machine and the quality of the ensuing product are strongly dependent on the processes occurring in the descending flame front. As it is not possible to measure flame front properties in a sintering bed directly, embedded thermocouples are used to provide information in this area. Through making some assumptions, it is possible to assess flame front properties using the obtained thermocouple profiles. Flame front speed, thickness and maximum temperature are identified as important parameters. The total heat transferred to the material from the flame front is a function of these parameters. Experimental results show that increasing flame front speed decreases residence time, maximum temperatures and total heat transferred to the bed. Only indicative trends can be obtained because of the variability in thermocouple results, which are inherent in the experimental technique. Coke combustion efficiency also depends on flame front speed.

In an iron ore sintering bed, the combustion behaviour of coke particles together with velocity of the flowing gas stream determines the temperature, width and speed of the traversing flame front. A bed heat treatment mathematical model was formulated in an earlier study to describe this complex relationship. An area of improvement in the model is the description of the coke combustion process, which is highly dependent on the resistances controlling the flow of gases to and from the coke particles. These vary for different coke particles because of the prior coarsening of the sinter mix by granulation. The characteristic structure of granules - nuclear particle with an adhering fines layer - indicates that gases have better access to finer coke particles. In this study, an available granulation model is integrated into the heat treatment model to provide a novel description of coke positioning within granules. In addition to this change, two endothermic reactions were introduced into the model. Using the previous and modified models, predicted bed temperature-time profiles as a function of position down the bed, were compared against embedded thermocouples results from seventeen laboratory sinter tests. Generally, the modified definition of coke combustion behaviour resulted in improved comparison with experimental results. In the sintering literature, studies have been reported on: the use of charcoal/biomass char to replace coke, the preferential placement of coke particles on the outside of granules, and varying the size distribution of the coke particles. Improving the access of gases to coke particles and decreasing coke size are comparable to using more reactive fuels. Combustion rate, efficiency and flame front properties are all influenced by fuel reactivity. Model predictions of changes in bed temperatures, flame front properties and sintering performance caused by fuel type, location and size are consistent with reported observations.

Controlling particulate emission from a sinter strand is important to minimizing its impact on the environment. Several factors influencing particulate emission from an iron ore sinter strand were investigated in the current work using a laboratory scale sinter pot. A blend fairly typical of that currently used in the Asia Pacific region, as well as another containing 30 mass% Marra Mamba ore that could represent a future ore blend were used. It was established that most of the particulates emitted were less than 1.18 mm and were mostly from the calcination and dried zones of the bed. In addition, most particulates were released from the bed after the wet zone in the bed had ceased to exist. This work suggests mix moisture and coke rate had a significant impact on particulate emissions. Increasing moisture from 5.5 to 9.0mass% decreased particulate emission while increasing coke content from 5.5 to 7.5mass% increased particulate emission. Therefore when altering the ore blend changes in mix moisture and coke rate may also need to be accounted for when evaluating the impact on particulate emission. It was also found that particulate emission could be decreased by decreasing sintering suction just before burn-through. © 2007 ISIJ.

Significant advances have been made to understand the iron ore sintering process. The laboratory sinter pot provides a good simulation of the process occurring on a sinter strand. The controlling variables and their inter-relationships can be obtained from carefully controlled pot tests. The sintering process has also been divided into the various sub-processes for study. Granulation has been studied very extensively; in recent years the flame front has been the focus of research efforts. There is now good understanding of the melt formation process and the dependence of this process on iron ore properties. More work on the interactive behavior of ores in a blend is required. The aim in sintering research must be to obtain sufficient fundamental understanding so that a generally applicable mechanism-based sintering model can be formulated. In the area of sinter quality, advances have also been made to understand the factors controlling sinter degradation and reduction.

Eleven single coals covering a wide rank range were coked individually in a pilot oven. The product cokes and their parent coals were characterized using conventional tests. In addition, coke micro-structure was quantified using 2-D image analysis. Although several coal and coke parameters were found to influence coke micro-structure, it was not possible to establish consistent trends for all the eleven samples. Clearly the structural transformation of coal to coke is a complex process influenced by many variables. Results also suggest that coke strength is dependent on micro-texture, micro-structure and the adhesion forces holding the assemblage together.

The nature of fracture and the factors that control the extent of fracture in the tumble-drum and drop-tower tests have been identified. The product-size distribution, on which the standard strength indices for these tests are based, and the breakage rate constants are shown to depend on a number of factors other than the strength of the lumps. The standard indices and rate constants are meaningful only in a comparative context and for events whose loading mechanism is similar. The results are used in combination with fracture mechanics theory to explain why different tumble-drum standards have been found to be not fully consistent. A more meaningful measure of strength could be the parameters of the Weibull function, i.e. scatter and average strength. © The Institution of Mining and Metallurgy 1997.

Studies were carried out to examine the effect of adding pisolitic limonite (Yandi) into an Australian iron ore blend, among which Yandi has higher porosity. The porosity increases further after dehydration, resulting in the formation of an extreme porous structure composed of fine hematite grains. This unique structure has a significant effect on the sintering properties of the blend. Pilot-scale sintering studies and plant trials showed that the productivity, sinter reductibility and low-temperature reduction size-degradation rate would change obviously when the Yandi content in the blend is more than 15%.
