麦尔兹石灰窑悬挂缸用耐磨浇注料的研究与应用

Research and application of wear-resistant castables for suspension cylinder of Maerz lime kiln

麦尔兹石灰窑悬挂缸用耐磨浇注料对石灰窑的正常生产具有举足轻重的作用。为了提高悬挂缸耐磨浇注料的使用性能和施工性能,系统研究了SiC细粉、堇青石、氧化铝空心球、烧结助剂硼酸以及纳米氧化物添加剂对刚玉质浇注料性能的影响。结果表明:所研发的悬挂缸用耐磨浇注料各方面性能均优于原用进口耐磨浇注料的指标,使用寿命有了明显的提升,超过当前使用的进口产品。

The wear-resistant castables for suspension cylinder of Maerz lime kiln play a crucial role in the normal production of the lime kiln.In order to improve the performance and construction applicability of wear-resistant castables for suspension cylinders,the effects of SiC fine powder,cordierite,hollow-structured alumina,sintering aids(boric acid),and nano oxide additives on the performance of corundum castables are systematically investigated.The results show that the developed wear-resistant castables for suspension cylinder have better performance than the originally used imported wear-resistant castables in all aspects,and their service life has been significantly improved,exceeding that of the current imported products used.
