制定合理的锰合金脱磷工艺是铁合金界的重要课题。为了解决这个难题,必须了解磷溶液在锰质熔体中的热力学特性。在著作[1]中先用测定锰从液态Mn—P合金中蒸发速率的方法来确定锰的活度,然后用图示积分法按方程进行数据换算,从而确定了1300℃时磷的活度与浓度的关系。在著作[2]里用Mn—P熔体载气 Develop a reasonable dephosphorization of manganese alloy ferroalloy sector is an important issue. In order to solve this problem, we must understand the thermodynamic properties of the phosphorus solution in the manganese-based melt. In the work [1], the activity of manganese was determined by measuring the evaporation rate of manganese from the liquid Mn-P alloy, and then the data was calculated by the equation of integration according to the equation, so as to determine the activity of phosphorus at 1300 ℃ Relationship with concentration. In the work [2] with Mn-P melt carrier gas
