在焊管生產的完整過程中（zhōng），退學熱度（dù）起著中藥材（cái）實際作（zuò）用，退學熱度有沒有實現明確要求熱度。焊管熱采用相應辦法解決通常是采用固溶熱采用相（xiàng）應辦法解決，也就是說人們庸庸碌碌更加所謂的“退學”，熱（rè）度適用（yòng）範圍為1040~1120℃(日本規範標準)。你也能（néng）夠借助退（tuì）學爐查看孔查看，退學區（qū）的銲接無縫鋼管加以應為白（bái）熾（chì）情況（kuàng），但沒發生軟化傳播。退學熱度為引物和沙盤聯係起來期間的熱度形式參數，當50%的引物和補充（chōng）有限序（xù）列露一手為雙鏈DNA積極分子時的熱度?它是產生相應作用PCR特殊（shū）性的較十分重要元素。在心胸情況下，退學熱度進行足額低，以確保（bǎo）引物同主要目的有限序列切實有效退學， 與此同時同時進行足額高，以進一步降低非特殊性聯係起來。較為合理的退學熱度從55℃到70℃。退學熱度通常進行設立比引物的 Tm低5℃。
Annealing temperature is the temperature parameter when primers and templates are combined. When 50% of primers and complementary sequences are double-stranded DNA molecules, temperature is an important factor affecting the specificity of PCR. Ideally, the annealing temperature is low enough to ensure the effective annealing of primers with the same target sequence, and high enough to reduce non-specific binding. Reasonable annealing temperature ranges from 55 to 70 C. The annealing temperature is generally set to be 5 C lower than the Tm of the primer. In the production of welded steel pipe, annealing temperature plays a role of traditional Chinese medicine, whether the annealing temperature reaches the prescribed temperature or not. The heat treatment of welded steel pipes is usually solid solution heat treatment, which is commonly called "annealing", and the temperature range is 1040 ~ 1120 ("Japan Standard"). You can also observe the holes in the annealing furnace. The welded steel pipe in the annealing zone should be incandescent, but there is no softening sag. 那（nà）會兒是退學（xué）空氣。通（tōng）常都（dōu）是使用純氫進行（háng）進行退學空氣（qì），空氣純度不（bú）過是99.99%上述，在滿足相關條件時空氣（qì）中另關於一部分是（shì）惰氣性體的話（huà），純度也能夠低一些（xiē），不（bú）過絕對化無法包括過多有關氧氣、蒸汽。著名退學爐應是進行緊閉的，與外邊大氣隔離;使用（yòng）重氫保護護氣的，左不過其中一個訴諸公論口是通的(用於燃點流出的重氫)。進行檢查的辦法能夠用胰子水抹在（zài）退學爐各式各樣搭接片裂（liè）縫處，看有沒有（yǒu）跑氣;在這當中最比較容易跑氣的（de）區域是退學爐進（jìn）管材（cái）的區域和出管材的區域，這一區域的密封圈尤其比（bǐ）較容易破壞，要常常進行檢查常常換。
Next is annealing atmosphere. Usually pure hydrogen is used as annealing atmosphere. The purity of the atmosphere is better than 99.99%. If the other part of the atmosphere is inert gas, the purity can be lower, but absolutely can not contain too much oxygen and water vapor. Bright annealing furnace should be closed, isolated from the outside air; using hydrogen as protective gas, only one exhaust port is open (used to ignite the exhaust hydrogen). Soap water can be used to smear the cracks in each joint of the annealing furnace to see if it runs out. The most easily runs out is the place where the annealing furnace enters and leaves the tube. The sealing rings in this place are particularly easy to wear and tear, so it is necessary to check and replace them frequently.
在非金屬進行加工範（fàn）圍，退學熱度是指退學時非金屬應受到實現的熱度。據相（xiàng）關教案進行介紹，有所區別非金屬材料的退學（xué）熱度為：鉑，900―1000℃；銅，650℃；黃銅（tóng），600―650℃；鎳銀（yín），650―680℃；鋁，283―350℃等。
In the field of metal processing, annealing temperature refers to the temperature at which the metal should be heated during annealing. According to the relevant literature, the annealing temperatures of different metal materials are: platinum, 900-1000 degrees C; copper, 650 degrees C; brass, 600-650 degrees C; nickel and silver, 650-680 degrees C; aluminium, 283-350 degrees C, etc.
最終（zhōng）是維護滾壓（yā）力。為的是避免發生微漏，爐內維護氣應堅持準（zhǔn）譜兒的持續正壓，在滿足相關條件時是（shì）重氫維護氣，通常具（jù）體要求20kBar上述。地（dì）方麵進（jìn）行檢（jiǎn）查爐體材料有沒有索然無味，首先裝爐，爐體材料一定要要吹幹;二是進爐（lú）的銲（hàn）接無（wú）縫鋼管有沒有留下過多水漬，尤（yóu）其管材方麵在滿足（zú）相關條件時有孔的話，多如牛毛別滲水參加了，要要不然就把火爐子空氣全風吹雨打了。
Finally, the protective pressure. In order to prevent slight leakage, the protective gas in the furnace should maintain a certain positive pressure. If it is hydrogen protective gas, the general requirement is more than 20 kBar. On the one hand, check whether the material of the furnace body is dry or not, and the material of the furnace body must be dried for the first time. On the other hand, whether there are excessive water stains left on the welded steel pipe entering the furnace, especially if there are holes in the pipe, don't let water leak in, or the atmosphere of the furnace will be destroyed completely.
