摘　　要：某厂在高品位冰铜吹炼过程中,时常发生锅炉辐射区结焦现象,如何避免锅炉结焦是铜转炉高品位冰铜吹炼面临的一大难题。发生锅炉结焦不仅会降低锅炉的热交换率,降低余热锅炉负压,还会造成锅炉刮板机损坏,同时也影响铜转炉的直收率,造成铜元素减少。为解决该厂锅炉结焦问题,详细分析了锅炉结焦产生的原因,并根据生产实践,提出转炉高品位冰铜吹炼过程中减少锅炉结焦的具体措施。During the process of high-grade copper smelting in a certain factory,coking often occurs in the radiation zone of the boiler.How to avoid boiler coking is a major challenge faced by high-grade copper smelting in copper converters.The occurrence of boiler coking not only reduces the heat exchange rate of the boiler and lowers the negative pressure of the waste heat boiler,but also causes damage to the boiler scraper,and also affects the yield of copper converter,resulting in a decrease in copper element.To solve the problem of boiler coking in the factory,a detailed analysis was conducted on the causes of boiler coking.Based on production practice,specific measures were proposed to reduce boiler coking during the smelting process of high-grade ice copper in the converter.
