style="text-indent:25px">有些小細節(jié)可能不注意就會造成嚴重的后果，損壞等直徑硅碳棒的本質，接下來介紹的這十個方面如果能夠很好的注意到就可以更好的發(fā)揮棒的價值。　　一、等直徑硅碳棒硬而脆，在運輸、開箱、安裝更換時要特別小心，輕拿、輕放、嚴防機械敲打，以免斷棒。　　二、新爐開始送電時，為了防止斷棒，應采用電爐額定功率的1/2空送一段時間，一切正常后再逐漸升高電壓，要按電爐升溫規(guī)范升溫，以免因功率過高炸斷等直徑硅碳棒。　　三、當棒穿過爐壁兩側（或上下）的棒孔后，應自由轉動360度，嚴防嚴格安裝與敲打，裝棒前可用與棒直徑的鐵管試裝。　　四、使用等直徑硅碳棒必須配置調壓器或可控硅調壓器及電壓、電流表和溫度自動控制儀表等。在使用過程中因棒氧化，電阻則逐漸增加，為保持爐溫正常，應提高使用電壓，當電壓提高到所用電壓器高限度仍不能滿足要求時，可停爐改變棒的接線方式在繼續(xù)使用。　　五、棒使用時每組棒應進行高溫阻值配阻，配阻的電值允許差為：≥φ12mm棒配阻，電阻值允差為≤0.2Ω ， ≤φ8mm棒配阻，電阻值允差為≤0.5Ω 。新疆直角硅碳棒經銷商</p><p
