Adhesion And Corrosion Mechanism And Improvement Of Material Properties Of Panzhihua Iron & Steel (Group) Co.BF Through

This paper mainly research on action between Ti-rich slag and material for BF through and put forward the mechanism of slag adhesion and mechanism of slag corrosion. On the basement of those researches, study the effect of non-oxide on the properties of material.Through chemical analysis, X-rays analysis and EPDX analysis about used material on BF through and surveying Ti-rich slag' 1 -t curve , find that the main factor of slag adhesion is the self character of Ti-rich slag, the dissolve of Al2O3 from material to slag and the reaction between slag and material.Through thermodynamics analysis, slag corrosion experiment of pure oxide and slag corrosion experiment of multi-material, find the main reason of serious corrosion of Ti-rich slag on material is that the solubility of Al2O3 in Ti-rich slag is higher than the solubility of Al2O3 in ordinary BF slag.On the basement of those researches, study the effect of non-oxide on the properties of material. Find that the material for BF through has good properties when the carbon grain was added into material.
