帶鋼(gang)入鋅(xin)鍋溫度(du)過高導致鋅(xin)液(ye)在帶鋼(gang)表面冷卻凝(ning)固時間延長，帶鋼(gang)經(jing)過氣刀后鋅(xin)液(ye)在重力(li)作用下繼續回(hui)流;

氣刀噴嘴與(yu)帶鋼(gang)之間距離波動造(zao)成(cheng)鋅(xin)層(ceng)厚度不均(jun);

帶鋼(gang)出(chu)鋅(xin)(xin)鍋后的抖動、沉沒輥輥系壓靠不(bu)合理、鋅(xin)(xin)鍋段(duan)帶鋼(gang)張力控(kong)制不(bu)當引起的帶鋼(gang)晃動等，都會影響鋅(xin)(xin)液回流的時間(jian)，也會因為(wei)帶鋼(gang)表(biao)面受(shou)力不(bu)均導致鋅(xin)(xin)層厚度不(bu)均從而產生鋅(xin)(xin)流紋;

噴淋塔(ta)安(an)(an)裝(zhuang)主要(yao)(yao)功能(neng)是為各廠房(fang)通風(feng)散熱，噴淋塔(ta)安(an)(an)裝(zhuang)，由風(feng)機(ji)房(fang)內的風(feng)機(ji)及(ji)分布(bu)在廠房(fang)內的通風(feng)管(guan)道組成，國內某站通風(feng)管(guan)道采(cai)用鍍(du)鋅鋼板，隨(sui)著服役(yi)年限延(yan)長部分區(qu)域(yu)出(chu)(chu)現(xian)腐蝕(shi)(shi)情況，且由于腐蝕(shi)(shi)及(ji)設(she)(she)計(ji)(ji)(ji)不(bu)足多次出(chu)(chu)現(xian)脫(tuo)落問(wen)(wen)(wen)題，環保(bao)設(she)(she)備噴淋塔(ta)安(an)(an)裝(zhuang)，該系統(tong)(tong)雖與核安(an)(an)全(quan)無關，但腐蝕(shi)(shi)脫(tuo)落會帶(dai)來工業安(an)(an)全(quan)問(wen)(wen)(wen)題，因此有必要(yao)(yao)對風(feng)管(guan)腐蝕(shi)(shi)特點、原因進行分析并給出(chu)(chu)解決(jue)方(fang)案，同時匯(hui)總結構設(she)(she)計(ji)(ji)(ji)不(bu)足問(wen)(wen)(wen)題及(ji)應對措施，可為現(xian)役(yi)電(dian)站糾正維修及(ji)新建電(dian)站通風(feng)系統(tong)(tong)設(she)(she)計(ji)(ji)(ji)提供指引。
