As一向认为是钢铁中的有害元素。除少数耐腐蚀钢种外,脱As是钢铁冶炼的一个问题。欲脱As必先知As在铁液中的热力学行为。文献中只报道过As的活度相互作用系数e_(As)~C,e_(As)~S及e_(As)~N。本文是继续前文研究As在Fe液中的热力学行为,旨在利用下列反应: 3(CaC_2)+2[As]=(Ca_3As_2)+6[C] (1) 求出Fe-As-C-j熔体中的
As has always been considered a harmful element in steel. With the exception of a few corrosion-resistant steels, off As is a problem in steel smelting. To take As As Prophet As in the molten iron in the thermodynamic behavior. Only reported in the literature activity of As interaction coefficients e_ (As) ~ C, e_ (As) ~ S and e_ (As) ~ N. In this paper, we continue to study the thermodynamic behavior of As in Fe solution. The purpose of this work is to find the melt of Fe-As-Cj with the following reaction: 3 (CaC_2) +2 [As] = (Ca_3As_2) +6 [C] middle
