Improving the Continuous Copper Converting Process Using Ferrous Calcium Silicate Slags

由于炉渣侵蚀而更换耐火材料是制铜过程中的一项主要成本。冶金学家需要找到一种更好的炉渣，既能保留现有炉渣的优点，又能减少对耐火材料的侵蚀。本项目将评估新提出的硅酸亚铁钙渣用于连续炼铜的适用性。结果将是：(1)提供有关SiO2-CaO-FeO渣体系性质的基本知识；(2)提供有关该渣的耐火侵蚀速率和机制的数据；(3)使铜冶炼行业能够评估该渣降低运营成本的潜力。

Replacement of refractories due to slag attack is a major cost in the copper making process. Metallurgists need to find a better slag which retains the benefits of current slags but is less aggressive towards refractories. This project will assess the suitability of a newly proposed ferrous calcium silicate slag for continuous copper converting. The outcomes will be to: (1) provide fundamental knowledge of the properties of the SiO2-CaO-FeO slag system, (2) provide data on the rate and mechanism of refractory attack by this slag and (3) enable the copper smelting industry to assess the potential of this slag to reduce operating costs.
