耐火磚(zhuan)有重質(zhi)(zhi)和輕質(zhi)(zhi)之(zhi)分(fen),輕質(zhi)(zhi)有比重、材質(zhi)(zhi)之(zhi)分(fen)。重質(zhi)(zhi)有堿(jian)性、酸(suan)性、中性之(zhi)分(fen)。那么(me),窯爐內襯(chen)怎么(me)選用(yong)合適的耐火磚(zhuan)呢?
1、首先要(yao)考慮材(cai)(cai)質(zhi)(zhi),選(xuan)擇什么材(cai)(cai)質(zhi)(zhi)要(yao)看爐子的溫度(du)(du)(du)、侵蝕程度(du)(du)(du)和性質(zhi)(zhi)。然后再(zai)看是(shi)(shi)輕(qing)(qing)質(zhi)(zhi)和重質(zhi)(zhi)的,如(ru)果是(shi)(shi)輕(qing)(qing)質(zhi)(zhi)的,也要(yao)看溫度(du)(du)(du)再(zai)選(xuan)定用(yong)輕(qing)(qing)質(zhi)(zhi)黏土磚(zhuan)(zhuan)或是(shi)(shi)輕(qing)(qing)質(zhi)(zhi)高(gao)鋁磚(zhuan)(zhuan),溫度(du)(du)(du)大(da)于(yu)1300℃的保溫層,就(jiu)要(yao)選(xuan)莫來(lai)石聚輕(qing)(qing)磚(zhuan)(zhuan)或是(shi)(shi)高(gao)鋁聚輕(qing)(qing)磚(zhuan)(zhuan)了,如(ru)果直(zhi)接接觸火(huo)焰就(jiu)要(yao)選(xuan)用(yong)剛玉(yu)莫來(lai)石聚輕(qing)(qing)磚(zhuan)(zhuan)或是(shi)(shi)氧化(hua)鋁空(kong)心球磚(zhuan)(zhuan)了。
2、如(ru)果(guo)是工作層,就要(yao)考慮重質耐火磚(zhuan),還是先看溫度,如(ru)果(guo)溫度在1000℃,不大于1100℃,就選用(yong)黏土(tu)磚(zhuan),如(ru)果(guo)大于1200℃,就要(yao)選擇(ze)高鋁(lv)磚(zhuan),當然(ran)溫度在1300-1350℃,要(yao)選擇(ze)一級高鋁(lv)磚(zhuan),1200℃選用(yong)二級高鋁(lv)磚(zhuan),或是三(san)級高鋁(lv)磚(zhuan)。1500℃以上就得用(yong)剛玉(yu)耐火磚(zhuan)了。
3、另外要(yao)考慮到(dao)窯爐內襯是酸性(xing)氣(qi)氛(fen)(fen)(fen)還是堿(jian)性(xing)氛(fen)(fen)(fen),酸性(xing)氣(qi)場就(jiu)(jiu)要(yao)選擇(ze)(ze)硅磚。如(ru)(ru)果玻璃窯池,那就(jiu)(jiu)是鋯質(zhi)澆(jiao)注耐火磚系列。如(ru)(ru)果是堿(jian)性(xing)氣(qi)氛(fen)(fen)(fen)要(yao)選擇(ze)(ze)堿(jian)性(xing)耐火磚,也(ye)就(jiu)(jiu)是鎂質(zhi)耐火磚系列。
4、還(huan)要(yao)(yao)考(kao)慮的(de)(de)(de)是設計的(de)(de)(de)耐(nai)火(huo)(huo)磚(zhuan)磚(zhuan)型(xing)(xing)尺寸(cun),要(yao)(yao)滿(man)足筑爐操作還(huan)必須考(kao)慮耐(nai)火(huo)(huo)磚(zhuan)的(de)(de)(de)生(sheng)(sheng)產(chan)方(fang)(fang)便(bian)(bian)(bian),因(yin)為耐(nai)火(huo)(huo)磚(zhuan)在成(cheng)型(xing)(xing)工序是否能機壓成(cheng)型(xing)(xing)、耐(nai)火(huo)(huo)磚(zhuan)的(de)(de)(de)尺寸(cun)太長(chang),不能機壓成(cheng)型(xing)(xing),手工成(cheng)型(xing)(xing)的(de)(de)(de)耐(nai)火(huo)(huo)磚(zhuan)強度低(di)于機壓成(cheng)型(xing)(xing)的(de)(de)(de)耐(nai)火(huo)(huo)磚(zhuan),強度低(di)勢必影(ying)響耐(nai)火(huo)(huo)磚(zhuan)的(de)(de)(de)使(shi)用(yong)壽命(ming)。所以(yi)選(xuan)擇耐(nai)火(huo)(huo)磚(zhuan)既(ji)要(yao)(yao)考(kao)慮方(fang)(fang)便(bian)(bian)(bian)筑爐操作,又要(yao)(yao)方(fang)(fang)便(bian)(bian)(bian)耐(nai)火(huo)(huo)磚(zhuan)生(sheng)(sheng)產(chan)廠家制造。當然,設計最好用(yong)國家在標的(de)(de)(de)型(xing)(xing)號。
像鼓風爐(lu)(lu)爐(lu)(lu)身上(shang)部(bu)(bu)用(yong)(yong)黏土(tu)磚(zhuan)(zhuan)砌筑(zhu);中部(bu)(bu)用(yong)(yong)鎂(mei)(mei)磚(zhuan)(zhuan),鎂(mei)(mei)鉻磚(zhuan)(zhuan)或鎂(mei)(mei)鉻磚(zhuan)(zhuan)砌筑(zhu);爐(lu)(lu)身下部(bu)(bu)及風口區(qu)溫度為(wei)1300℃用(yong)(yong)高鋁(lv)磚(zhuan)(zhuan),單個部(bu)(bu)位在1500℃,運用(yong)(yong)條件嚴苛(ke)的選用(yong)(yong)細(xi)密黏土(tu)磚(zhuan)(zhuan),高鋁(lv)磚(zhuan)(zhuan)或鎂(mei)(mei)鉻磚(zhuan)(zhuan)。爐(lu)(lu)缸用(yong)(yong)鎂(mei)(mei)磚(zhuan)(zhuan),鎂(mei)(mei)鉻磚(zhuan)(zhuan)砌筑(zhu)。
鉛(qian)(qian)(qian)鋅密閉鼓(gu)風爐,是處理鉛(qian)(qian)(qian)鋅氧化礦或鉛(qian)(qian)(qian)鋅的新爐型,是直接鍛(duan)煉(lian)出產鉛(qian)(qian)(qian)和鋅,爐缸和爐腰(yao)選用鎂鉻磚砌筑(zhu)(zhu)(zhu),爐頂及與鉛(qian)(qian)(qian)霧室(shi)銜接處用致密黏(nian)土磚砌筑(zhu)(zhu)(zhu),側墻用黏(nian)土結合碳(tan)化硅(gui)磚砌筑(zhu)(zhu)(zhu)。鉛(qian)(qian)(qian)鋅別離室(shi)的底和頂用致密黏(nian)土磚砌筑(zhu)(zhu)(zhu)。鉛(qian)(qian)(qian)液流(liu)槽(cao)和出鉛(qian)(qian)(qian)槽(cao)的槽(cao)底,用二級高鋁耐火磚砌筑(zhu)(zhu)(zhu),槽(cao)壁用鎂鉻磚或鉻磚砌筑(zhu)(zhu)(zhu)。
總之,選(xuan)用耐火磚是根據不同爐型、不同溫度、不同侵蝕(shi)程度而選(xuan)用的。
