高鋁耐火磚產品介紹：

?

????高鋁耐火磚，即氧化鋁含量在48以上的一種硅酸鋁質耐火材料。由礬土或其他氧化鋁含量**的原料經成型和煅燒而成。熱穩定性高，耐火度在1770以上。抗渣性較好。

?

高鋁耐火磚的分類：

?

通常分為三類：

等：Al2O3含量75-80；

等：Al2O3含量6075；

等：Al2O3含量4860；

?

生產工藝：

?

????高鋁耐火磚和粘土磚的成型生產方法基本相同，只是有些工藝參數有所差別。也有粉碎混煉成型干燥燒成檢驗包裝等工藝過程。低溫下其壓應力承受較好但高溫時略有減低所以窯中棧放**1米。高鋁耐火磚和多熟料粘土磚的生產工藝類似不同之處在于配料中熟料比例**可高達9099熟料在破碎前需分級揀選和篩分除鐵燒成溫度**如、等高鋁質耐火磚用隧道窯燒成時一般為15001600。

?

高鋁耐火磚用途：

?

????主要用于砌筑高爐、熱風爐、電爐爐頂、鼓風爐、反射爐、回轉窯內襯。此外，高鋁耐火磚還廣泛地用做平爐蓄熱式格子磚、澆注系統用的塞頭、水口磚等。
