| 摘 要： | 借助FactSage热力学软件分别对1873、1823和1773 K三个不同温度下60Si2MnA弹簧钢液与MnO--SiO2--Al2O3系、CaO--Al2O3--SiO2系和CaO--Al2O3--SiO2--15%MgO系夹杂物间的平衡进行了计算.通过上述计算分析,确定了三个不同温度下分别形成上述低熔点夹杂物时所对应的钢液成分.经过对比还发现:低温更有利于钢液在低溶解氧含量条件下实现上述不同类型夹杂物的低熔点化控制.钢液中生成低熔点SiO2--Al2O3--CaO--15%MgO系夹杂物要比生成低熔点SiO2--Al2O3--CaO系夹杂物所需的钢液Al含量高很多,这在实际生产中更容易控制.

| Abstract: | Equilibria between 60Si2MnA molten spring steel and such low melting point inclusions as MnO-SiO2-Al2O3 inclusions,CaO-Al2O3-SiO2 inclusions and CaO-Al2O3-SiO2-15%MgO inclusions were thermodynamically studied by the thermodynamic software FactSage at three different temperatures of 1 873,1 823 and 1 773 K.On the basis of these calculations,the compositions of the liquid steel were determined when these low melting point inclusions formed at the different temperatures.Simultaneously,it was also discovered by... |
