Hot Metal De-Sulphurisation by KR Process
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
The objective of this project is to present an analysis of the use of residual mixtures in the pig iron desulphurization process. This study involves the Effect of Aluminium dross, fluorspar, and lime. These mixtures were made and added to a liquid hot metal with known chemical composition at a temperature of 1300 to 14200C. The mass of each element was calculated from its chemical analysis and compared with an industrial mixture. All of the mixtures used in the experiments were stirred by a mechanical stirrer. Samples were collected, and analysis was performed to check sulphur variation in the bath with time. The results were analyzed and the verified that it was possible to use as a desulfurizers. This project seeks to optimize parameters, reduce the cost of desulphurization and the consumption of operation about KR pre-treatment of hot metal. Based on the theoretical analysis of physical chemistry in metallurgy, simulation experiments of the KR desulphurization of hot metal were in a laboratory and the composition of the desulphurization was optimized, by means of chemical analysis. The optimized parameters of the process are put forward.
