用不同返回比原料在真空感应炉中冶炼１Ｊ２２软磁合金时出现了不同的工艺现象，分析了这些现象产生的原因，采取相应工艺措施后使不同返回比原料试制的１Ｊ２２合金热轧带材的性能和质量均能达到国标要求，提高返回比对节约贵重金属钴和降低生产成本意义重大．
The different process phenomena occurred when smelting 1J22 soft magnetic alloy with different return ratio raw materials in a vacuum induction furnace. The causes of these phenomena were analyzed. After the corresponding technological measures were taken, different 1J22 alloy hot rolled strip Performance and quality can meet the national standard requirements, improve the return to save more than the precious metal cobalt and reduce the cost of production of great significance.
