摘要
分析了高炉 中频炉双联熔炼短流程生产工艺的特点,采用液态金属状态测评系统研究短流程铁液状态。通过比较短流程生产和常规流程生产的铁液状态,提出了短流程铁液状态调控措施,来改善其凝固组织和力学性能。结果表明,高炉 中频炉双联短流程工艺能生产出完全符合技术要求的高质量铸件。同时,探讨了短流程生产工艺在能源消耗、环境保护、生产成本等方面的优势。
It was investigated that the short-cut process of producing high quality iron castings by duplex melting with blast furnace and medium frequency induction furnace. The quality of iron melt was paid the same attention as the chemical composition and temperature during smelting process and was analyzed by using a self-developed melt quality evaluation system. The melt quality, microstructure and mechanical properties obtained in common medium frequency induction melting process and the short-cut process were compared respectively. Correspondingly, the adjusting methods for the quality of iron melt were advised. It was shown that after quality adjustment high quality iron castings like engine blocks produced by the shot-cut process can meet the specification of the conventional process. It was analyzed that the great merits of energy saving, environment protection and cost efficiency in addition.
