升液管入爐前應當充分預熱，如果用燃氣炬加熱，要內(nèi)外上下緩慢均勻，避免局部過度受熱。溫度達到600°C罐體發(fā)暗紅時即可，時間大約三十分鐘左右。也可以把升液管架在爐中，讓管的底口距鋁液面2厘米左右，等待管壁全部發(fā)紅后(時間大約三十分鐘)即可緩慢放入鋁液中。此項操作既可以把管內(nèi)的潮氣烘干，又避免升液管因突然升溫而引起炸裂。升液管使用時一-定要注意減少對管口的敲擊，特別是堵鋁后不能硬砸。在更換模具、修理設備時，盡量減少沖擊震動，對升液管暴露的部位要注意保溫，防止急冷。扒渣時注意不要直接碰撞升液管，加注鋁液時注意避免直接沖澆到升液管體上。停爐維修設備必須要把升液管拿出爐時，不要把熱的升液管直接倒放在地_上，應該用耐火材料包裹后立放在不受冷風直吹處。升液管的使用壽命與設備本身的結(jié)構(gòu)特點和使用中的各種條件及升液管徑尺寸有關。機臺鋼性好震動較小，爐體移位較少且平穩(wěn)、模具更換不頻繁、管體受熱溫差不大、管徑較粗壁厚均勻且不易堵鋁的，使用壽命較長。因受氮化硅升液管材料自身特性的影響，特提出一-些應多加注意的原則:1、盡量減輕機械碰撞，特別是在搬運及安裝調(diào)試時，猛烈的撞擊和不均勻的受力，將極大縮短升液管的使用壽命。</p></p><br
