一、灰熔點測定儀的安裝1安裝硅碳管：屬于單螺紋硅碳管。先卸下爐體兩端擋板，先把硅碳管小心推入管式爐體，然后分別在硅碳管的兩端安裝上卡子，并安裝電源導線。在把爐體兩端擋板安裝上，安裝擋板時注意給硅碳管留1~2毫米的活動空間。否則會按斷，或者升溫熱脹冷縮擠斷。把硅碳管出來的個兩個導線固定到灰熔點測定儀后面的輸出接線柱上。測量出爐體中心，把熱電偶插入到位。并接入控制器上熱電偶接線端，注意紅為正極，其他色為負極。2把灰熔點測定儀電源線接入電網(wǎng)。3打開控制器開關和爐體開關，點擊控制器上的--國標--啟動，觀察升溫正常后關閉電源。二、灰熔點測定方法與步驟1灰樣制備。利用工業(yè)分析方法中的慢灰，來加工灰樣，至少3~5克再用瑪瑙研體研磨，密封保存。2灰錐制備。5克糊精溶于100毫升蒸餾水中，用其溶液1~2點滴入煤灰上，充分攪拌摻和，利用灰錐模版和小刀制成灰錐。放在玻璃上。風干備用。3灰錐安裝。把干燥后的灰錐放在灰錐板的三角槽中，可以用氧化鎂沾下。4氣氛控制：在鋼玉舟內(nèi)放入和標定一樣質量的石墨或者無煙煤。（石墨的重量是在灰熔點標定達標所需要石墨的重量）5把剛玉舟推入爐體，使灰錐正好在熱電偶下方。擰緊爐體螺絲蓋。6打開儀器電源。吉林硅碳管經(jīng)銷商奧翔硅碳生產(chǎn)的產(chǎn)品受到用戶的一致稱贊。</p><div

粗端式硅碳棒硬而脆，在搬運、開箱和安裝、維修時要特別小心，以免損壞。電爐在開始通電運行時，要逐漸緩慢升壓，不可一次加滿負荷，否則會因沖擊電流過大、而造成硅碳棒損壞。硅碳棒在長期使用后，電阻會緩慢增加，為確保運行正常，延長使用壽命，比較好配備相應的調(diào)壓變壓器。硅碳棒受潮后易崩裂，GD棒接點受潮后易斷損，因此，硅碳棒在存放，安裝使用過程中要注意防潮，以免影響其壽命。1、幾何尺寸的選擇電爐的爐膛是由被加熱物的尺寸推算而決定，因而硅碳管的尺寸也相應確定下來，現(xiàn)舉例說明如下：如被加熱物是?70×500mm的石英管（這里的500mm是指石英管的受熱區(qū)，實際上石英管還要長）則硅碳管的規(guī)格可選用?90/80×500/100，二爐膛的高鋁管則可選用其內(nèi)徑為100mm，其長度要略長于500mm。2、硅碳棒保護管使用的功率硅碳管使用的功率決定于爐子的保溫條件，幾何尺寸及到達的溫度。對于較好的保溫條件，恒溫后，硅碳管發(fā)熱區(qū)內(nèi)表面的溫度與被加熱物的溫度相差≦50℃。我們可以利用下式先計算硅碳管發(fā)熱部單位表面積的負荷。吉林硅碳管經(jīng)銷商</p><p
