Abstract
ABSTRACT The influence of Al2O3/TiO2/Na2O component in steelmaking slag on the corrosion rate and mechanism of MgO refractories is significant for promoting the development of non-fluorine fluxes in steelmaking processes. In this study, static method was used to analyze the effects of Al2O3/TiO2/Na2O components on the corrosion rate of MgO refractory, which was characterized by measuring the MgO content in the final slag after the same reaction time. The results showed the corrosion rate of the MgO refractory was controlled by the diffusion of FetO in the slag to the crucible and the chemical reaction of MgO with FetO. When the amount of each oxide was less than 15%, the ability of the slags to corrode the MgO refractory material were as follows: Na2O
期刊介绍：
Ironmaking & Steelmaking: Processes, Products and Applications monitors international technological advances in the industry with a strong element of engineering and product related material. First class refereed papers from the international iron and steel community cover all stages of the process, from ironmaking and its attendant technologies, through casting and steelmaking, to rolling, forming and delivery of the product, including monitoring, quality assurance and environmental issues. The journal also carries research profiles, features on technological and industry developments and expert reviews on major conferences.
