| 为实现水泥熟料生产的节能降耗与资源综合利用，探索工业副产炭黑作为辅助燃料在水泥熟料生产中的应用可行性，解决炭黑掺入后可能出现的氯离子超标、熟料强度下降等问题，本文结合某公司一线熟料生产线（同时使用炭黑和氟化钙污泥）的生产实践、岩相分析数据与 XRD 检测结果，研究了煤粉制备过程中炭黑掺入量与掺入位置的优化效果，以及配套强度补偿方案的应用效果。通过优选仅在分解炉掺入且用量控制在5 t/h以内的工艺，可将熟料氯离子含量控制在合理范围；同时采用优化熟料KH值、搭配氟化钙污泥的补偿方案，提升熟料3 d、28 d强度，成功抵消炭黑掺入对熟料强度的不利影响。岩相显微观测与 XRD 图谱表明，最优工艺下熟料矿物结晶均匀、C3S 含量充足、无有害物相，微观结构满足优质熟料要求。研究表明，炭黑在水泥熟料生产中合理选择掺入位置并精准控制掺量，可实现资源回收利用与熟料质量稳定的双重目标，为水泥行业节能降碳提供新路径。 |

| To achieve energy saving, consumption reduction, and comprehensive resource utilization in cement clinker production, this study explores the feasibility of using carbon black as an auxiliary fuel in cement clinker production, and addresses the issues of excessive chloride ion content and reduced clinker strength that may arise after carbon black incorporation. Based on the production practice of a company's clinker production line (using both carbon black and calcium fluoride sludge simultaneously), combined with petrographic analysis data and XRD test results, this paper investigates the optimization effects of the amount and feeding location of carbon black during coal powder preparation, as well as the application effect of a supporting strength compensation scheme. By adopting the optimized process of feeding carbon black only into the calciner and controlling the dosage within 5 t/h, the chloride ion content in clinker can be kept within a reasonable range. Meanwhile, a compensation scheme involving optimization of the clinker KH value and the addition of calcium fluoride sludge is employed to enhance the 3 d and 28 d strength of clinker, successfully offsetting the adverse effect of carbon black incorporation on clinker strength. Petrographic microscopic observations and XRD patterns indicate that under the optimal process, the clinker minerals are uniformly crystallized, with sufficient C3S content and no harmful phases, and the microstructure meets the requirements for high-quality clinker. The research demonstrates that by rationally selecting the feeding location and precisely controlling the dosage of carbon black in cement clinker production, the dual goals of resource recycling and stable clinker quality can be achieved, providing a new pathway for energy conservation and carbon reduction in the cement industry. |
