摘　　要：介绍了回收利用不锈钢厂烟道灰和氧化铁皮中铬的前期试验研究。在烟道灰和氧化铁皮中配入水和焦粉等物质,在不同的配比下,对样品压块并测定和分析了其抗压强度。找出了样品块强度能够满足冶炼要求的合适工艺参数。根据所用的烟道灰、氧化铁皮和焦粉条件,为达到较高的抗压强度,烟道灰单独压块的原料合适含水量为12%;氧化铁皮与烟道灰的合适配比为1∶4;烟道灰与焦粉配合时,合适的焦粉含量为12%,相应的合适含水量为14%。The experiment and relevant results on recycling use of chrome in dust and scale from stainless steel-making process is introduced in this paper. The compressive strength of the briquets of dust and scale were measured with different water contents and powdered coke . Based on the relevant data, the experimental data of compressive strength was analyzed. The appropriate technological and process parameters of the sample which can satisfy the condition of smelting were selected. It is found that to reach the good compressive strength, the appropriate water content in briquetting dust is 12 % for dust; the appropriate ration of scale and dust is 1：4; the appropriate powdered coke content is 12% in dust, and the appropriate water content is 1496 correspondingly.
