Analysis of Structural Components Existing in Steel Making Slag Sampled from Steel Making-Continuous Casting Flow Sheet

Résumé

Hereby paper work aims to identify and analyze the structural constituents from the steel making shop slag. Therefore, slag specimens sampled from different stages of steel making-continuous casting flow sheet in Mittal Steel Galaţi: after desulphuration, after converter tapping, from LF area, after continuous casting. By X ray difractometer analysis the existing phases in investigated stages based on diffracted crystallographic planes enhanced the variation graphs of lines intensity depending on diffraction angles drawn. The results achieved together with the followed technological parameters formed the data basis in order to perform a detailed analysis about progressing of each technological stage itemized (apparition conditions, effects) setting the requirements for optimization of steel making-continuous casting flow sheet in Mittal Steel Galati ferrous metallurgy area. The recorded information corroborated by values of physical-chemical characteristics of slag investigated should allow the making and testing of several technological solutions for capitalization and recirculating of these materials.
