Abstract

There are several known technologies and processes for desulpurization of hot metal used for the production of ductile and compacted graphite iron, but none of them do not deal with an aspect of continuous desulphurization of cupola iron as it is used in IMP Livar d.d. Low calcium carbide yield achieved by applied mechanical method of adding desulphurization mixture in the stream of iron is conected with higher production costs; variations of sulfur in basic iron melt, sulphide inclusions in ductile iron, slag disposal with high percentage of unreacted calcium carbide. The purpose of the research project is to reduce the pressure to the environment by the slag depositing on account of the procedure optimization of the melt desulphurization in the flow laddle and of the development of the alternative reagent mixture with the possibility of the slag recycling. Expected research procedure includes the desulphurization technology of the foundry-plant IMP Livar d.d. and the analysis of used agent for the desulphurization, melt, slag and lining. By the study of the melt flow on the physical water model of the flow laddle the reaction zone will be established and the modification of the technology of adding of desulphurization agent will be suggested. On the base of the study of thermodynamics and the reaction kinetics of desulphurization the optimal demands of the composition and granulation of the reactant mixture will be established to assure maximal yield of the process.
