34孔(kong)硅(gui)磚是目(mu)前被(bei)世界煉鐵界廣泛認同(tong)和接受的一種(zhong)熱(re)(re)(re)交換能力強、蓄(xu)(xu)熱(re)(re)(re)面積大、通(tong)氣順暢、阻力小等(deng)諸多優各型34孔(kong)硅(gui)磚各型34孔(kong)硅(gui)磚越熱(re)(re)(re)工特性的載熱(re)(re)(re)蓄(xu)(xu)熱(re)(re)(re)體。34孔(kong)硅(gui)磚是一種(zhong)傳熱(re)(re)(re)介(jie)質(zhi)，應用(yong)在高(gao)爐(lu)熱(re)(re)(re)風(feng)爐(lu)蓄(xu)(xu)熱(re)(re)(re)室(shi)里(li)，通(tong)常是在蓄(xu)(xu)熱(re)(re)(re)室(shi)里(li)有(you)序排列，在“燒爐(lu)期”間起蓄(xu)(xu)熱(re)(re)(re)作用(yong)，在“送風(feng)期”間則(ze)通(tong)過對流熱(re)(re)(re)交換和輻射熱(re)(re)(re)交換，把(ba)冷風(feng)加熱(re)(re)(re)成熱(re)(re)(re)風(feng)。

34孔硅磚應用

目前34孔硅磚主要(yao)用在高爐熱風(feng)爐和火焰爐上。

34孔(kong)(kong)硅(gui)(gui)磚(zhuan)(zhuan)(zhuan)主要用(yong)在(zai)熱(re)(re)(re)(re)風(feng)(feng)(feng)爐(lu)(lu)的蓄熱(re)(re)(re)(re)室里(li)，由結構(gou)一(yi)(yi)定的帶(dai)格孔(kong)(kong)的34孔(kong)(kong)硅(gui)(gui)磚(zhuan)(zhuan)(zhuan)有序排(pai)列，34孔(kong)(kong)硅(gui)(gui)磚(zhuan)(zhuan)(zhuan)上下通(tong)(tong)(tong)孔(kong)(kong)可(ke)任由氣體通(tong)(tong)(tong)過(guo)。根據(ju)不同(tong)溫度區域的技術要求(qiu)，一(yi)(yi)般(ban)選用(yong)硅(gui)(gui)質34孔(kong)(kong)硅(gui)(gui)磚(zhuan)(zhuan)(zhuan)、粘土磚(zhuan)(zhuan)(zhuan)等(deng)，在(zai)一(yi)(yi)些熱(re)(re)(re)(re)風(feng)(feng)(feng)爐(lu)(lu)里(li)，也(ye)有選擇(ze)高(gao)(gao)鋁(lv)磚(zhuan)(zhuan)(zhuan)、莫來(lai)石(shi)磚(zhuan)(zhuan)(zhuan)、硅(gui)(gui)線石(shi)磚(zhuan)(zhuan)(zhuan)等(deng)。熱(re)(re)(re)(re)風(feng)(feng)(feng)爐(lu)(lu)的作用(yong)是把鼓(gu)風(feng)(feng)(feng)機(ji)送至高(gao)(gao)爐(lu)(lu)的冷風(feng)(feng)(feng)加(jia)(jia)熱(re)(re)(re)(re)成(cheng)熱(re)(re)(re)(re)風(feng)(feng)(feng)，然后(hou)(hou)，熱(re)(re)(re)(re)風(feng)(feng)(feng)通(tong)(tong)(tong)過(guo)熱(re)(re)(re)(re)風(feng)(feng)(feng)管送至高(gao)(gao)爐(lu)(lu)內(nei)進行燃燒反應(ying)。高(gao)(gao)爐(lu)(lu)熱(re)(re)(re)(re)風(feng)(feng)(feng)爐(lu)(lu)有燒爐(lu)(lu)期(qi)(qi)和送風(feng)(feng)(feng)期(qi)(qi)，兩個(ge)工(gong)作期(qi)(qi)周期(qi)(qi)地輪換(huan)。在(zai)燒爐(lu)(lu)期(qi)(qi)中，燃燒后(hou)(hou)的高(gao)(gao)溫煙氣從(cong)熱(re)(re)(re)(re)風(feng)(feng)(feng)爐(lu)(lu)34孔(kong)(kong)硅(gui)(gui)磚(zhuan)(zhuan)(zhuan)的孔(kong)(kong)洞中通(tong)(tong)(tong)過(guo)，把熱(re)(re)(re)(re)量傳給34孔(kong)(kong)硅(gui)(gui)磚(zhuan)(zhuan)(zhuan)在(zai)送風(feng)(feng)(feng)期(qi)(qi)中，從(cong)鼓(gu)風(feng)(feng)(feng)機(ji)出來(lai)的冷風(feng)(feng)(feng)進入(ru)熱(re)(re)(re)(re)風(feng)(feng)(feng)爐(lu)(lu)，被34孔(kong)(kong)硅(gui)(gui)磚(zhuan)(zhuan)(zhuan)加(jia)(jia)熱(re)(re)(re)(re)成(cheng)熱(re)(re)(re)(re)風(feng)(feng)(feng)后(hou)(hou)，通(tong)(tong)(tong)過(guo)熱(re)(re)(re)(re)風(feng)(feng)(feng)管送至高(gao)(gao)爐(lu)(lu)內(nei)。
