摘要
对某厂生产的高碳硬线盘条中的夹杂物成分进行了统计分析,并通过热力学计算软件FactSage计算分析了Al-Si-Mn复合脱氧条件下高碳硬线盘条中Al2O3-SiO2-MgO-CaO-MnO五元系夹杂物低熔点区域的控制范围.在五元系低熔点区域内Al2O3的质量分数可达56%,CaO的质量分数为20%～30%.
A statistical analysis on the compositions of inclusions in high carbon wire rod produced by one steel company was conducted. And the compositions of low melting point inclusions of Al2O3-SiO2-MgO-CaO-MnO system in a high carbon wire rod steel with Al-Si-Mn deoxidization were calculated and analyzed by the thermodynamic software FactSage. In the low melting point zone of the Al2O3-SiO2-MgO-CaO-MnO system for a high carbon wire rod steel,the Al2O3 content should reach 56%,and CaO 20%～30%.
