34孔(kong)硅磚是(shi)目前被世界(jie)煉鐵界(jie)廣泛認同和接受(shou)的一種熱(re)(re)(re)(re)(re)(re)交換能力(li)強、蓄(xu)(xu)熱(re)(re)(re)(re)(re)(re)面積大、通(tong)氣順暢、阻力(li)小(xiao)等諸多優(you)各型(xing)34孔(kong)硅磚各型(xing)34孔(kong)硅磚越(yue)熱(re)(re)(re)(re)(re)(re)工特性(xing)的載熱(re)(re)(re)(re)(re)(re)蓄(xu)(xu)熱(re)(re)(re)(re)(re)(re)體。34孔(kong)硅磚是(shi)一種傳熱(re)(re)(re)(re)(re)(re)介質,應用在(zai)高爐(lu)熱(re)(re)(re)(re)(re)(re)風爐(lu)蓄(xu)(xu)熱(re)(re)(re)(re)(re)(re)室里,通(tong)常是(shi)在(zai)蓄(xu)(xu)熱(re)(re)(re)(re)(re)(re)室里有序排列,在(zai)“燒(shao)爐(lu)期(qi)”間起蓄(xu)(xu)熱(re)(re)(re)(re)(re)(re)作用,在(zai)“送風期(qi)”間則通(tong)過對流熱(re)(re)(re)(re)(re)(re)交換和輻(fu)射(she)熱(re)(re)(re)(re)(re)(re)交換,把冷風加(jia)熱(re)(re)(re)(re)(re)(re)成(cheng)熱(re)(re)(re)(re)(re)(re)風。
34孔硅磚應用
目前34孔硅磚主要用在高爐熱風爐和火焰(yan)爐上。
34孔(kong)(kong)硅(gui)磚(zhuan)主要用在(zai)熱(re)(re)(re)風(feng)爐(lu)(lu)的(de)(de)蓄熱(re)(re)(re)室里,由(you)結構一定的(de)(de)帶格孔(kong)(kong)的(de)(de)34孔(kong)(kong)硅(gui)磚(zhuan)有(you)(you)序排列,34孔(kong)(kong)硅(gui)磚(zhuan)上(shang)下通(tong)(tong)(tong)孔(kong)(kong)可(ke)任由(you)氣體(ti)通(tong)(tong)(tong)過(guo)。根據不同溫(wen)度區域(yu)的(de)(de)技術要求,一般選用硅(gui)質34孔(kong)(kong)硅(gui)磚(zhuan)、粘土磚(zhuan)等(deng),在(zai)一些熱(re)(re)(re)風(feng)爐(lu)(lu)里,也有(you)(you)選擇高(gao)(gao)鋁磚(zhuan)、莫來(lai)石磚(zhuan)、硅(gui)線石磚(zhuan)等(deng)。熱(re)(re)(re)風(feng)爐(lu)(lu)的(de)(de)作用是把(ba)鼓風(feng)機送(song)(song)(song)至高(gao)(gao)爐(lu)(lu)的(de)(de)冷(leng)風(feng)加熱(re)(re)(re)成熱(re)(re)(re)風(feng),然(ran)后(hou)(hou)(hou),熱(re)(re)(re)風(feng)通(tong)(tong)(tong)過(guo)熱(re)(re)(re)風(feng)管(guan)送(song)(song)(song)至高(gao)(gao)爐(lu)(lu)內進行燃(ran)燒反應。高(gao)(gao)爐(lu)(lu)熱(re)(re)(re)風(feng)爐(lu)(lu)有(you)(you)燒爐(lu)(lu)期(qi)和送(song)(song)(song)風(feng)期(qi),兩個工作期(qi)周期(qi)地輪換。在(zai)燒爐(lu)(lu)期(qi)中,燃(ran)燒后(hou)(hou)(hou)的(de)(de)高(gao)(gao)溫(wen)煙(yan)氣從熱(re)(re)(re)風(feng)爐(lu)(lu)34孔(kong)(kong)硅(gui)磚(zhuan)的(de)(de)孔(kong)(kong)洞中通(tong)(tong)(tong)過(guo),把(ba)熱(re)(re)(re)量傳給(gei)34孔(kong)(kong)硅(gui)磚(zhuan)在(zai)送(song)(song)(song)風(feng)期(qi)中,從鼓風(feng)機出(chu)來(lai)的(de)(de)冷(leng)風(feng)進入熱(re)(re)(re)風(feng)爐(lu)(lu),被34孔(kong)(kong)硅(gui)磚(zhuan)加熱(re)(re)(re)成熱(re)(re)(re)風(feng)后(hou)(hou)(hou),通(tong)(tong)(tong)過(guo)熱(re)(re)(re)風(feng)管(guan)送(song)(song)(song)至高(gao)(gao)爐(lu)(lu)內。
