本文简要的介绍“倒包”法试验工艺要点,试验结果,冶金质量及经济效益。并对试验数据进行了初步分析和比较,证明了“倒包”法对提高铬的回收率效果显著。1Cr_(18)Ni_9Ti钢由86.02％提高到94.38％,超低碳型不锈钢由76.00％提高到86.82％。并且使用的设备简单,操作方便,易于推广。 This article briefly introduces the key points of the “inverted packet” test, the test results, metallurgical quality and economic benefits. The preliminary analysis and comparison of the experimental data proves that the “inverted packet” method has a significant effect on increasing the chromium recovery rate. 1Cr_ (18) Ni_9Ti steels increased from 86.02% to 94.38%, ultra-low carbon stainless steels increased from 76.00% to 86.82%. And the use of equipment is simple, easy to operate, easy to promote.
