Due to the softening-melting of the burden in the cohesive zone of the blast furnace, the ore layer becomes compacted and the gas passes predominantly through the sandwiched coke layer known as coke slits. For improved productivity and reduced coke rate, it is required to minimize the size and lower the position of the cohesive zone in the blast furnace. This work is designed by arriving at a slag composition through actual experimentations which will ensure the lowering of the cohesive zone of the blast furnace with simultaneous decrease in the difference between the softening temperature (ST) and flow temperature (FT) of the slag. Slag samples from SAIL, Rourkela were collected and their flow characteristics were measured using the heating microscope. With the same composition as obtained from the steel plant, a synthetic slag was prepared in the laboratory using pure oxides, by another group. It was melted to 1600 °C and then water quenched to form the glassy state. Flow characteristics for the same were also determined. The flow characteristics data of Blast Furnace slag were compared with that obtained from synthetic slag. All the slag samples were sent to DISIR, Rajgangpur for slag analysis as well as to determine the mineralogical phases present in them, for which the slag samples were heated to 1500 °C followed by slow cooling to convert them to crystalline form. Then, XRD analysis was done to determine the mineralogical phases. Finally, with relevant phase diagram study, we arrived at a composition which will ensure the lowering of cohesive zone.

Investigation Of Thermal Properties Of Blast Furnace Slag To Improve Process Energy Efficiency written by Sara Yasipourtehrani and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2016 with Iron slag categories.
Blast furnace slag (BFS) is the main by-product of iron making and is produced in large amounts worldwide. Analysing the properties of BFS, such as viscosity and heat exchange, at high-temperature conditions will help improve energy efficiency during the process. One of the steps in the iron making process is to heat the pig iron up to 1500°C for the next phase of steel-making. During this heating, a significant amount of energy is transferred to the BFS, and utilising some of this heat energy from the slag to contribute to heating pig iron would achieve energy efficiency. To improve energy usage, it is necessary to understand behaviour of the slags with differing compositions at varying temperatures. This knowledge is also important to assess the slag for further applications, such as use as concrete or cementitious material; however, the cooling process is known to have a significant effect on the end product properties and determine the end use of the slag. This study determines the thermal properties of selected slag samples using several in-situ experimental techniques. By comparing the chemical composition of the slags and their thermal behaviour, the effect of magnesium oxide and aluminium oxide was evident. Besides, the content of silicon dioxide had an effect on crystallization temperature and network strength.
