Abstract

To evaluate the phase and structural components of grinding media made of cast iron with a high content of copper and silicon obtained by extracting iron from copper-smelting slags, phase equilibria in the iron – carbon system were calculated with the addition of copper and silicon in various concentrations. The calculation was carried out using the ThermoCalc software package with construction of phase diagrams by the Calphad method. At the same time, temperatures of the beginning of phase transformations were estimated taking into account the presence of all thermodynamically possible phases in the system at various combinations of copper and silicon concentrations.
铜和硅对铁-碳体系中相变的影响
为了评估通过从铜冶炼渣中提取铁而获得的铜硅含量较高的铸铁研磨介质的相和结构成分,计算了添加不同浓度的铜和硅时铁-碳体系中的相平衡。计算使用 ThermoCalc 软件包,并通过 Calphad 方法构建相图。同时,考虑到在不同的铜和硅浓度组合下,体系中可能存在的所有热力学相,对相变开始时的温度进行了估算。
