摘要
针对转炉大面修补料使用寿命短、烧结时间长等问题,加入铝粉作为助燃剂、铁鳞作为促烧剂,并引入促流剂,研究了新型结合体系对材料性能的影响。结果表明:Al粉的引入可明显提高材料强度,但同时导致材料流动性降低,加入量为1%时,材料综合性能最好;铁鳞起到了促烧作用,加入量以1%为宜;促流剂B可明显提高材料的流动性,加入量为2%。改进后的修补料使用寿命提高两倍。
Because converter patching refractory service life was too shorter and sintering time was too longer, adding Al powder as buming-rate accelerator, iron scale as acceleration of sintering and running formulation, the effects of new binder system were discussed. The results show that： the patching refractory strength is increased obviously when the Al powder was added, and the running quality is reduced. When the AI powder addition is 1%, the iron scale addition is 1%, the running formulation addition is 2%, and the best combination property was obtained.
