熱風爐使用過程中經常會遇到一些這樣那樣的問題,使用熱風爐的朋友們除了仔細閱讀使用說明書外,還需要注意以下問題以便延長熱風爐使用壽命,保持熱風爐優良的性能。 沒有啦

使用過程中經常會遇到一些這樣那樣的問題,使用的朋友們除了仔細閱讀使用說明書外,還需要注意以下問題以便延長使用壽命,保持優良的性能。
In order to prolong the service life of hot blast stove and maintain its excellent performance, the friends who use hot blast stove need to pay attention to the following problems besides carefully reading the instructions.
1、應編制使用維護操作規程,建立運行記錄和修理檔案,統計運行累積工作時間,加強日常維護,掌握設備技術狀態變化趨勢,及早發現故障損壞苗頭,避免屬于事故搶修性質的熱修,并根據負荷和工作狀況,提前有針對性地準備修理用料,編制修理工藝。
1. Operational rules for operation and maintenance should be worked out, operation records and repair files should be established, cumulative working hours of operation should be counted, daily maintenance should be strengthened, changing trend of equipment technical status should be grasped, failure and damage seemingly detected as soon as possible, hot repair with the nature of emergency repair should be avoided, and needles should be provided in advance according to the load and working condition of hot blast stove. Prepare repair materials and work out repair technology.
2、不能超負荷使用沒備,合金元件的最高使用溫度是指元件在干燥空氣中允許的本身表面溫度,并不是指加熱物質的溫度或電熱元件周圍的溫度。要注意電熱元件本身的溫度一股比它周圍的介質溫度或被加熱溫度高100℃。
2. Do not overload without equipment. The maximum service temperature of alloy elements refers to the allowable surface temperature of elements in dry air, not the temperature of heating materials or the temperature around the elements. It should be noted that the temperature of the electrothermal element itself is 100 C higher than that of the surrounding medium or the heated temperature.
3、升溫后,不能長時間開啟爐門。當溫度高于400℃時,不得急劇冷卻。對于電熱元件在溫度高、冷熱變化大情況下,容易引起氧化掉皮。對于鉬加熱爐,EI常使用維護中注意應冷卻至200℃以下方可停送保護氣。
3. Hot blast stove can not open the door for a long time after heating up. When the temperature is higher than 400 C, it should not be cooled sharply. It is easy to cause oxidation peeling of electrothermal components when the temperature is high and the temperature changes greatly. For molybdenum heating furnace, EI should be cooled to below 200 before shutting down the protective gas.
①水分排出期O~200℃,是泥漿中的水分和砌體中潮氣的排出期,必須打開爐門,同時保溫時間較長。
The water discharging period is O - 200 C, which is the discharging period of water in mud and moisture in masonry. It is necessary to open the furnace door and keep it warm for a long time.
②砌體膨脹期是砌體開始膨脹及膨脹變形期,這時升溫不超過50℃/h。
(2) The expansion period of masonry is the initial expansion and expansion deformation period of masonry, when the temperature rise does not exceed 50 C/h.
③保溫期600℃以上,每升高100~200℃,要保溫一段時間,過急易損壞砌體。
(3) The insulation period is over 600 C, and every 100-200 C increase, the masonry should be heated for a period of time, which is too quick and easy to damage.
