進口石墨轉子

描述

石墨轉子是鋁合金熔煉設備的一部分。鋁合金熔煉過程中會產生氫氣和氧化渣,需要通過精煉除氣器凈化去除。石墨轉子是精煉除氣器不可缺少的附件之一。液態鋁合金的凈化處理是提高鋁合金綜合性能的主要手段。凈化過程中,將凈化氣體和溶劑混合,將石墨轉子吹入鋁熔體中進行凈化。

石墨轉子的工作原理是旋轉的轉子將吹入鋁熔體的氮氣(或氬氣)破碎成大量分散的氣泡,分散在金屬熔體中。在熔體中,氣泡通過氣體分壓差和表面吸附的原理吸收熔體中的氫氣,并吸收氧化廢渣。隨著氣泡的上升,它們被帶出熔體表面,從而凈化熔體。由于氣泡分散得很細,與旋轉的熔體混合均勻,然后呈螺旋狀慢慢上浮。與熔體接觸時間長,不會形成持續的直上氣流,從而去除鋁熔體中的有害氫,凈化效果明顯提高。
