摘　　要：安钢干熄焦年修期间焦炭水分偏高且波动较大,针对焦炭水分的影响因素,采取相应措施规范熄焦车接焦、控水时间及凉焦台循环放焦操作,优化熄焦大小水量时间,在保证没有红焦的前提下,减少熄焦时间,最终控制焦炭水分在8%左右,保证了高炉的稳定顺行。During annual maintenance for CDQ system in Anyang Iron&Steel,the coke moisture stays high and fluctuates.In view of the factors influencing the coke moisture,measures were taken such as to standardize coke receiving by quenching car,to control dewatering time and coke discharging on the coke wharf,to optimize quenching time for high and low water volume,as well as to minimize the quenching water volume to maintain the coke moisture around 8%on the premise of no red hot coke so as to ensure stable operation of blast furnace.
