摘要
江苏沙钢集团有限公司的焦化厂干熄焦系统运行中,锅炉防磨罩冲刷磨损严重,甚至发生锅炉吊顶管磨穿爆管等问题,因此开展了干熄焦炉防磨罩耐磨涂层喷涂技术的研发及应用.通过对干熄焦炉防磨罩磨损的研究,提出了采用热喷涂技术进行镀层实验,并结合喷涂材料及沙钢焦化厂干熄焦工艺参数,设计了涂层加工的工艺结构,采用扫描电镜、显微硬度计、万能试验机等设备检测涂层性能,成功研发出耐磨性优良的干熄焦炉防磨罩,提高了干熄焦生产效率.
When CDQ system in coking plant of Jiangsu Shagang Group Co., Ltd. is operated, the wear mask of boiler is badly worn, or even the ceiling tubes of boiler are worn out and burst. Spray technology of wear-resistant coating of the wear mask in CDQ furnace is studied and carried out. Through the study of wearing of wear-resistant coating in CDQ furnace, coating experiment is carried out by the use of thermal spray coating technology. Crafts of coating process are designed combining with spraying material and process parameters of CDQ in coking plant of Shagang Group Co., Ltd. Coating performance is detected by using scanning electron microscopy, micro hardness tester, universal testing machines and other equipment. Wear mask of CDQ furnace is successfully developed to improve the production efficiency.
