Abstract

The concentration regions of the phase equilibria of the components in a metallic Fe–Mg–Al–Ca–C–O melt at a temperature of 1600°C have been calculated and built for low-, medium-, and high-carbon steels by simulating the solubility surfaces of the components in a metal. The conditions of formation of calcium aluminate inclusions in the system are determined. Carbon is shown to influence the sequence of phase formation with the participation of strong deoxidizers, such as calcium, magnesium, and aluminum. The liquid metal is found to contain composition regions in equilibrium with a gaseous CO-based phase or a gaseous phase based on calcium and magnesium vapors.

镁存在下铝和钙脱氧的钢液中的相平衡

摘要

计算并建立了低碳，中碳和高碳钢在温度为1600°C的金属Fe–Mg–Al–Ca–C–O熔体中各成分的相平衡的浓度范围。模拟组分在金属中的溶解度表面。确定系统中铝酸钙夹杂物形成的条件。碳在强脱氧剂（例如钙，镁和铝）的参与下会影响相形成的顺序。发现液态金属包含与基于CO的气态相或基于钙和镁蒸气的气相平衡的组成区域。
