【摘要】 针对陕西钢铁研究所软磁合金1JHA1原生产工艺真空感应熔炼(VIM)过程中出现的问题，从降低生产成本，提高带材的表面质量角度出发，进行了生产工艺的改进与研究，并且就这种工艺改进对合金质量的影响进行了分析。本论文旨在通过对冶炼工艺的探讨，提出影响1JHA1质量的因素和降低成本的有效措施，从而为生产提供一种行之有效的冶炼工艺路线。 进行了冶炼过程不同脱氧工艺制度(SiCa合金和SiCaBa合金)的对照试验。结果显示，采用非真空感应熔炼(AIM)方法生产1JHA1合金具有工艺上和经济上的可行性。所试炼的合金化学成分易于控制、磁性能高、质量较好、成本降低。 确定了非真空感应冶炼1JHA1合金的脱氧工艺制度，进行了成分、金相和夹杂物显微分析，对合金的冶金质量控制、夹杂物控制及成本控制提出了自己的见解。更多还原

【Abstract】 Based on the problems occurred in the former vacuum induction smelting process for soft magnetic alloy 1JHA1 in Shaanxi Iron and Steel Research Institute, smelting process improvement and research has been carried out to enhance surface quality and lower production cost. This paper analyzes the influence of different factors on quality and proposes effective measures to lower cost. The main aim is to draw a satisfying process route by means of discussing the smelting process.During the experiment, contrast trials of different deoxidization and modification agents (SiCa alloy and SiCaBa alloy) are made. The experimental results show that it is feasible to produce 1JHA1 by air induction melting based on technics and economics. The productions have good chemical compositions and magnetic properties as well as surface quality at lower cost.According to the analysis of chemical compositions and magnetic properties along with nonmetallic inclusion microstructure, this paper put forward opinions on the control of component and nonmetallic inclusion modification together with production cost. Smelting Process route with suitable deoxidization technology of air induction melting for soft magnetic alloy 1JHA1 is also fixed.更多还原
