    article discusses the application of a liquid slag viscosity model as worksheet functions in Microsoft Excel This follows on a previous post that discusses the model and background in greater detail together with the implementation thereof in a Microsoft Silverlight application This application of the viscosity model in Excel is specifically useful as it be more easily integrated with existing mass and energy balance calculations and used to calculate viscosities for multiple slag chemical compositions and temperatures The remainder of this article discusses the worksheet functions and the use thereof as per a demonstration spreadsheet that can be download following instructions below Continue reading Slag Ternary Diagramming Tool Posted on 6 February 2011 9 October 2015 by Jacques Muller In this post I introduce and demonstrate a ternary diagramming tool to calculate and analyse metallurgical slag properties such as viscosity liquidus temperature etc In short this could be used to calculate slag liquid viscosity and then to calculate and plot contours on a ternary diagram It is also possible to import property values from a csv file as a function of the varied components plotted on the diagram and then to calculate and plot the contour values The ternary diagramming tool can be found here This software was again based on the Microsoft Silverlight technology which make it possible to have rich internet application inside your browser or to easily install the software on your computer More on this can be found in a previous post The ternary diagram software component was developed in a way to easily be used in other applications as well Continue reading Smelting furnace refractory and freeze lining heat transfer model Posted on 11 December 2010 9 October 2015 by Jacques Muller In this post I would like to illustrate how to model heat transfer through the refractory of a smelting furnace and how to estimate the thickness of a freeze lining on the hot face This is targeted at readers familiar with smelting furnaces and would like to utilize measured data to evaluate the heat transfer performance or alternatively to investigate refractory options Although complex phenomena exists in the furnace influencing heat transfer and the formation of freeze lining which are in some cases largely unknown a simple approach is demonstrated to model the most important effects observed Continue reading A tool to calculate slag liquid viscosity using Silverlight Posted on 8 November 2010 27 November 2015 by Jacques Muller In this blog I present and discuss a tool to calculate metallurgical slag liquid viscosity This tool has been developed using the Microsoft Silverlight technology which will also be discussed in a bit more detail than was done in the previous post 2015 11 27 Update The slag liquid viscosity calculation was programmed in an updated Microsoft Excel add in and is discussed and available for download here Continue reading Kohonen Self Organizing Maps for Process Applications using Silverlight Posted on 6 November 2010 9 October 2015 by Jacques Muller In this blog I

  • Modelling of the Iron Ore Pelletising Process | Algoness
    properties of the fired pellets produced in the induration process are modelled as functions of the green pellet properties raw material properties e g concentrate surface area size distribution and the induration process variables e g temperature A flowsheet modelling approach is used with model components developed for pellet induration in either a grate section or a rotary kiln and where the processing and distribution of gas streams are modelled with mixers splitters blowers combustion components etc Since gas streams are recycled to optimally use energy added to the pelletising process the model has to be calculated until it converges The induration process in the grate and kiln components is modelled in detail using the finite difference method FDM solving heat and mass transfer as functions of the green pellet properties packed bed permeability and other process operating parameters The sub models with which the gas and pellets temperature and composition are modelled over the height and length dimensions for the grate kiln and cooler components include Gas solids heat transfer radiation convection and conduction Water evaporation condensation Coke combustion within pellets Magnetite oxidation Limestone dolomite calcination Fuel combustion injected natural gas or solid fuels Fig 1 The pelletising process model structure showing inputs and outputs of the balling and induration processes models Induration Process Model Results As examples of the model output results generated with the straight grate and grate kiln cooler pelletising process configurations of the induration model component are presented below Process variables calculated with the induration process model are visually displayed on a process flowsheet as heat maps over the height and length dimensions also showing properties of the gas streams total rate temperature pressure flowing between the induration process components An example of this is shown below with the heat maps displaying pellets temperature Fig 2 Induration model results of a grate kiln cooler pelletising process with heat maps showing pellets temperature Process variables are also illustrated on XY graphs showing values calculated along the lengths of the grate and kiln process components and at different depths of the pellet grate For a typical grate kiln cooler pelletising process the figures below show the temperature of both the gases and pellets along the length of the kiln as well as the Abrasion Index AI and Cold Crushing Strength CCS as it changes over the length of the kiln Fig 3 1 Pellets and gases temperature and 2 the pellets Abrasion Index AI and Cold Crushing Strength CCS along the kiln length in a grate kiln cooler pelletising process The figures below show for a typical straight grate pelletising process the temperature and Cold Crushing Strength CCS of pellets at different depths and along the length of the grate Fig 4 1 Pellets temperature and 2 Cold Crushing Strength CCS along the total grate length at different depths of the grate in a straight grate pelletising process Process Analyses and Optimisation This pelletising process model is useful to determine the effects of variations in process operating
