kinetics of corrosion of bn zro2 sic ceramics in contact with si Killed Steel
Journal of the American Ceramic Society, 2015Co-Authors: Abhishek Kumar, Vivek Thapliyal, D G C Robertson, Jeffrey D. SmithAbstract:The mechanism and kinetics of corrosion of BN–ZrO2–SiC (MYCROSINT®SO43) by molten Si-Killed Steel was studied. Isothermal corrosion tests were performed for duration between 2 and 8 h. Refractory and Steel composition and morphology changes were investigated. A kinetic model using process simulation software METSIM and thermochemical software FactSage was developed to understand refractory–Steel interactions. The corrosion process showed a deviation from parabolic kinetics and was fitted by a combination of linear and parabolic terms. It was determined that corrosion of the BN–ZrO2–SiC refractory was governed by dissolution of SiC and BN and removal of ZrO2 as the other phases were eliminated.

Total oxygen prediction model of ultra-low carbon aluminum Killed Steel in RH treatment and its application
Journal of University of Science and Technology Beijing, 2009Co-Authors: Cai Kai-keAbstract:Based on the experimental data of ultra-low carbon aluminum Killed Steel in a 300 t ladle of RH treatment,a model for predicting the total quantitatively oxygen content of molten Steel was established. Some factors such as treatment time,argon flow rate,molten Steel circulation rate,snorkel diameter,FeO and MnO content in ladle slag were considered in the model. Potential improvements for RH operation were discussed. According to model analysis,the methods for promoting inclusion rising are increasing the argon flow and enlarging the snorkel diameter,but they have proper ranges.

Improvement of CSP castability in low carbon Al-Killed Steel
Journal of University of Science and Technology Beijing, 2005Co-Authors: Cai Kai-keAbstract:The fundamental or common thermodynamical relations between calcium-treated aluminium-Killed molten Steel and non-metallic inclusions were discussed. The thermodynamic properties of low carbon Al-Killed Steel and inclusions in the CSP process were calculated using the interaction coefficients of activity and the Bjorkvall method respectively. A detailed analysis of the CaO-Al_2O_3 binary system established the modification of solid alumina inclusions via the following intermediate phases: 3CaO·Al_2O_3, CaO·Al_2O_3, liquid phase 12CaO·7Al_2O_3 and CaS. The conditions of forming liquid calcium-aluminate inclusions and avoiding the formation of CaS in calcium-treated aluminium-Killed molten Steel were also discussed using these thermodynamic relations. The results are in good agreement with the plant data.

Analysis of Traditional Process on Deep-Drawing Properties of Cold-Rolled Low Carbon Killed Steel Sheet
Ironmaking & Steelmaking, 2010Co-Authors: Ju WeiAbstract:The production of low carbon Al-Killed Steel has been separated into CCR and TSCR.Though analysis of microstructure,SEM,EDS and texture,the stamping properties have been studied on structure,grain,free cement and main texture.Furthermore,the reasons of stamping cracking have been investigated.Practice shows if three critical factors,including free cement,ferrite grain and AlN precipitation,were controlled reasonably in traditional process,the stamping properties could satisfy the requirement of DC04,up to micro-carbon mechanical,making enormous economic benefits.

Analysis on Surface Peeling of Cold-rolled Low Carbon Killed Steel
Physics Examination and Testing, 2009Co-Authors: Ju WeiAbstract:In recent years,the objection to quality of cold-rolled strip mostly fall into surface defects.The surface defect patterns of cold-rolled strip are differ in thousands ways and the reasons are varied also.Various processes,including Steelmaking,hot-rolling,cold-rolling,can cause surface defect directly or indirectly.The surface peelings by cold-rolling were analyzed comprehensively on low carbon Killed Steel for cold rolling mill of Tangshan Jianlong Industrial Co Ltd.The research has proved that the subsurface inclusions and bubbles are origin of the surface peeling.Through correctly detecting and analyzing defect,the reason of defects are identified.The product quality are improved by taking corresponding measures.
