分類

1、線狀螺旋環繞(rao)電熱輻射管

這種電(dian)熱(re)輻射管由(you)耐熱(re)合金鋼套管和加(jia)(jia)熱(re)器組成，加(jia)(jia)熱(re)器一般由(you)電(dian)熱(re)絲繞在(zai)開有(you)螺(luo)旋溝槽的耐熱(re)絕緣陶瓷管芯上(shang)。

2、帶狀螺(luo)旋(xuan)環繞電熱輻射管

這種加熱器的結構基本(ben)上(shang)與種結構相同，只是加熱元(yuan)件采(cai)用(yong)電阻帶繞制，管芯多為多個(ge)分(fen)組式管芯組成，在(zai)同樣(yang)表面負荷下，熱輻射面大(da)，材料可節省，一(yi)般大(da)功率(lv)點(dian)加熱輻射管采(cai)用(yong)此種形式。

3、軸向(xiang)波折形籠(long)柜式(shi)電(dian)熱(re)輻(fu)射管（俗稱鼠籠(long)式(shi)）

其結(jie)構是將加(jia)熱元件的電阻絲（帶）彎(wan)成“U”形串入多塊絕緣耐(nai)(nai)高(gao)溫(wen)的陶瓷支撐盤中，中間用一(yi)根耐(nai)(nai)熱棒固定(ding)，這種輻射管壽命較長。

特點

1、核心材料采用直流氬弧焊接，使表面負(fu)荷、電阻差等各(ge)項技術指標得到保證。

2、耐熱絕(jue)緣瓷件熱震性好、耐高(gao)溫、壽(shou)命長。有高(gao)、中、低(di)溫爐(lu)用(yong)(yong)和特種(zhong)氣氛爐(lu)用(yong)(yong)規格(ge)任(ren)意選用(yong)(yong)。外(wai)套(tao)管(guan)系采用(yong)(yong)無縫耐高(gao)溫合金(jin)管(guan)及(ji)板卷管(guan)、離心鑄(zhu)管(guan)、非金(jin)屬專用(yong)(yong)抗滲碳(tan)套(tao)管(guan)等。安裝、檢(jian)測、維修方便，均在爐(lu)外(wai)進行。

3、結構緊湊，性能穩定、單根功率大、使用壽命是普通電加(jia)熱管(guan)的幾倍。
