關于高溫輥道窯的用途以及特點,大家可以參考小編之前的文章進行了解,今天小編將簡單為大家介紹一下該如何設計輥道窯的尺寸,對于高溫輥道窯尺寸的設計一般包括了:內高、內寬、拱中心角,其中:
1、高(gao)溫(wen)輥道窯的(de)(de)內(nei)高(gao)一般(ban)指的(de)(de)是(shi)窯車臺面至窯頂(ding)的(de)(de)空(kong)間高(gao)度(du),內(nei)高(gao)的(de)(de)多少一般(ban)由材料所能允許的(de)(de)堆垛(duo)高(gao)度(du)來確(que)定,例如:鎂磚由于其(qi)荷重軟(ruan)化溫(wen)度(du)和他的(de)(de)燒成溫(wen)度(du)接近(jin),磚跺高(gao)度(du)不宜太高(gao),窯內(nei)高(gao)通(tong)常在(zai)1米(mi)左右;而硅磚由于其(qi)荷重軟(ruan)化溫(wen)度(du)高(gao),其(qi)窯內(nei)高(gao)通(tong)常在(zai)1.9—2.1米(mi)。一般(ban)情況下,磚跺上(shang)下所允許的(de)(de)溫(wen)差也是(shi)考慮(lv)窯內(nei)高(gao)時應注意的(de)(de)影響因素之一。窯高(gao)增(zeng)加(jia),上(shang)下溫(wen)差加(jia)大,容易造成燒成質量不均(jun)勻。
2、高溫輥道窯的內寬一般指的是窯內兩側窯墻之間的距離,與窯的產量和允許的溫差有關,隨著高溫輥道窯窯寬的增加而增加,一旦寬度過大則會引發中心溫度偏低,現在市場上很多廠家的高溫輥道窯多采用扁寬型斷面設計,窯的寬高比一般為HB,其中B為窯的內寬,H為窯的內高。
3、拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)心(xin)角(jiao)(jiao):我們(men)知道(dao)(dao),高溫輥道(dao)(dao)窯的(de)窯頂(ding)有拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)頂(ding)和(he)吊頂(ding)兩種類型。耐火材料(liao)輥道(dao)(dao)窯,燒成(cheng)溫度高,多為拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)頂(ding)窯,拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)頂(ding)采用(yong)楔形磚砌筑,拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)心(xin)角(jiao)(jiao)的(de)選擇很重要,拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)心(xin)角(jiao)(jiao)太(tai)小(xiao),拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)磚受(shou)力太(tai)大,在(zai)使用(yong)過程中(zhong)還會產(chan)生(sheng)下沉現象;反(fan)之若拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)心(xin)角(jiao)(jiao)大,拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)半徑(jing)(jing)小(xiao),當受(shou)熱時,拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)磚膨(peng)脹,拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)會被擠起而產(chan)生(sheng)開裂現象,同時拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)過高,拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)頂(ding)制品之間孔(kong)隙加大,增(zeng)加上下溫差。拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)心(xin)角(jiao)(jiao)一半在(zai)60°~180°之間,其(qi)(qi)中(zhong)60°的(de)拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)心(xin)角(jiao)(jiao)采用(yong)較多。它的(de)拱(gong)(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)心(xin)角(jiao)(jiao)采用(yong)60°,其(qi)(qi)半徑(jing)(jing)為3016mm,矢高為403mm。
作為一種產量高、能耗低的高效率窯種,高溫輥道窯被廣泛用于鈷酸鋰、錳酸鋰、鋰離子三元材料、氧化鈷、珠光粉、超純粉體、磁性材料、石油催化劑、玻璃晶化等在1200℃以下工作溫度使用,并具有結構簡單、操作便利等優點。
