冷拔（bá）無縫鋼管在生產中也是不斷地進行發揮出來巨大的作用的，但是冷拔無縫鋼管在進行維（wéi）護和保（bǎo）養（yǎng）的過程中並不是一番風順的，由於這樣或者是那樣的（de）原因導致冷拔無縫鋼（gāng）管生鏽的現象是（shì）比較（jiào）多的，對於冷拔無縫（féng）鋼管生鏽的後果是不能進行使用了，喪失了冷拔無縫鋼（gāng）管原來的特性。這個時（shí）候就要進行酸洗了，那麽冷拔無縫鋼（gāng）管是怎樣進行酸洗除鏽的呢?
Cold-drawn seamless steel pipe is also constantly playing a huge role in production, but the process of maintenance and maintenance of cold-drawn seamless steel pipe is not smooth, because of this or that reason, the phenomenon of cold-drawn seamless steel pipe rusting is more, for cold-drawn seamless steel pipe rusting. The result is that it can not be used and the original characteristics of cold-drawn seamless steel tube are lost. At this time, acid cleaning is needed. How do cold-drawn seamless steel tubes remove rust by acid cleaning?
冷拔無縫鋼管及氧化物在鹽酸和硫（liú）酸中的溶（róng）解度不同。20℃時，每100g試（shì）件在10%的鹽（yán）酸（suān）溶液中可溶解7.5g三氧化二鐵，而在10%的硫酸溶液中隻能溶解0.98g三（sān）氧化二鐵。在（zài）相同（tóng）溫度（dù）、濃度下，鹽酸對（duì）鐵件的溶解度大於硫酸（suān）7倍（bèi）以上。所以在鋼鐵表麵除鏽多用鹽酸。鹽酸除（chú）鏽（xiù）速度快、效率高、不產生（shēng）氫脆、表麵狀態好（hǎo），在配製洗液時（shí）又比硫酸安全、經濟。
The solubility of cold-drawn seamless steel tube and oxide in hydrochloric acid and sulfuric acid is different. Ferric trioxide can be dissolved 7.5 g in 10% hydrochloric acid solution and 0.98 g in 10% sulfuric acid solution at 20 C. At the same temperature and concentration, the solubility of hydrochloric acid to iron parts is more than 7 times higher than that of sulfuric acid. Therefore, hydrochloric acid is often used to remove rust on steel surface. Hydrochloric acid has the advantages of fast rust removal, high efficiency, no hydrogen embrittlement and good surface condition. It is safer and more economical than sulfuric acid in the preparation of lotion.
用酸洗的辦法（fǎ）危害工人身體健康，排放廢液會造成工業汙染（rǎn），需要"三廢"治理（lǐ），酸洗後還很容易產生氧化皮鏽層，如果鋼鐵設（shè）備長期暴露在空氣中，會很快被腐蝕，人們正在尋求能替代此種方法的新工（gōng）藝。在冷加工行業（yè）如：接管、拉絲、擠壓、深拉延（yán）等工（gōng）序，要求（qiú）磷化膜提供（gòng）減（jiǎn）摩潤滑性能，一般采用鋅係磷化，一是（shì）鋅係磷（lín）化膜皂化後形成潤滑性很好的硬脂酸鋅層，二是鋅係（xì）磷化操作溫度比較低，可在40、60或90℃條（tiáo）件下進行磷化處理，磷化時（shí）間4～10min，有時甚至（zhì）幾十秒鍾即可，磷化（huà）膜重（chóng）量要（yào）求≥3g/m2便可。
The method of pickling endangers the health of workers. Discharging waste liquor will cause industrial pollution. It needs to be treated by "three wastes". It is easy to produce oxide rust layer after pickling. If steel equipment is exposed to air for a long time, it will be corroded quickly. People are looking for a new technology to replace this method. In cold processing industry, such as takeover, wire drawing, extrusion and deep drawing, phosphating film is required to provide antifriction and lubricity performance. Zinc phosphating is generally used. First, zinc stearate layer with good lubricity is formed after saponification of zinc phosphating film. Second, zinc phosphating operation temperature is relatively low, and it can be phosphated at 40, 60 or 90 C. After treatment, the phosphating time is 4-10 minutes, sometimes even tens of seconds, and the weight of the phosphating film is more than 3g/m2.
冷拔無縫鋼管的酸（suān）洗（xǐ）要依據化學原理進行，但是酸（suān）洗比（bǐ）較費（fèi）時間和經曆，大家可以根據自己（jǐ）的實際情況（kuàng）進行適當的去選擇，另外當冷拔冷拔無縫鋼管出（chū）現生鏽的時候不要急（jí）於用肥皂水和洗（xǐ）衣液（yè）進行衝洗，以免出現各（gè）種各樣的不（bú）利的影響（xiǎng）!
The pickling of cold-drawn seamless steel pipe should be carried out according to chemical principle, but pickling takes time and experience. Everyone can choose it appropriately according to their own actual situation. In addition, when the cold-drawn seamless steel pipe rusts, don't rush to wash it with soap water and laundry liquid in order to avoid all kinds of disadvantage. Influence!
