| 摘 要： | 生产低碳铝镇静钢过程中,为了控制夹杂物形态,一般要对其进行钙处理。如何使钙处理过程中生成液态的钙铝酸盐夹杂是生产控制的难点和重点。通过理论计算得出在一定条件下Ca]-Al]、S]-Al]关系图,以某低碳铝镇静钢为例,当w(Al])为0.03%时,控制w(Ca])为(9~15.8)×10-6,可以生成成分接近(CaO)12(Al2O3)7的液相夹杂。钢中w(S])为30×10-6,w(Al])为0.03%~0.04%,温度降低到1 723 K以下时,在(CaO)12(Al2O3)7上会析出CaS。

| Abstract: | Generally,in order to control the morphologies of inclusions,the low carbon Al-killed steel should be treated with calcium.It's difficult and important to make the inclusions to be liquid(CaO)x(Al2O3)y inclusions though the processing control.Correlation figures between solute calcium and solute aluminum,also between solute sulfur and solute aluminum have been established theoretically.Taking a kind of low carbon Al-killed steel for example,when the solute aluminium is 0.03 percent and the calcium is contro... |
