中文摘要: 通过分析目前国内外大吨位真空自耗电弧炉普遍采用的结构型式,指出了这些型式的电弧炉存在的缺陷和不足,提出了一种双炉室真空自耗电弧炉结构。详细介绍了该SZHL8双炉室真空自耗电弧炉的主体设计方案、主要技术特点和性能指标,重点介绍了研制过程中主要解决的技术难点,包括双炉室共用整流电源技术、水冷炉室结构的优化、坩埚冷却系统、智能熔速控制系统、充氩熔炼实时控制系统等。
Abstract:Based on the analysis of structure styles which had been adopted widely on domestic and foreign large tonnage vacuum arc remelting(VAR) furnaces at present,this paper pointed out some shortcomings and deficiencies existing in these types of VAR furnaces, and put forward a new double chambers type VAR furnace structure. This paper also gave a detailed introduction on the main body structure design,main technical features and performance index of the SZHL8 double chambers type VAR furnace, especially focuses on the main technical issue being necessary to solve during development, including double chambers sharing one set of rectifiers, structure optimizing of water cooling furnace chamber,cooling system of crucible, intelligent melt rate control system and partial pressure real time control system.
