介绍了热镀锌立式还原退火炉的生产实践,通过采取空煤比的合理调整、炉温的优化控制、生产节奏的合理掌握、N2净化站的应用、热值的稳定控制等技术措施有效解决了炉墙掉砖和锌层漏镀问题,改善了辊面结瘤问题,从而大大减少了停炉开盖次数,避免了非正常停炉启炉时的废品量,延长了退火炉使用周期,使退火炉的各项经济技术指标迈上了一个新台阶,为镀锌机组的连续稳定运行提供了保障。
The production practice of hot-dip galvanizing vertical reduction annealing furnace is introduced. By adopting reasonable adjustment of empty coal ratio, optimal control of furnace temperature, reasonable control of production rhythm, application of N2 purification station and stable control of calorific value The invention solves the problems of out-of-furnace and out-of-layer zinc plating, improves the nodularity of the roller surface, greatly reduces the number of open-door shutdowns, avoids the amount of waste products during abnormal shutdown, and prolongs the service life of the annealing furnace , So that the annealing furnace economic and technical indicators to a new level for the continuous operation of galvanized units provided a guarantee.
