大多数的新配件为防止氧化生锈,都是涂油或上腊后用纸包装保管的。使用启封时,可对不同零件分别采用水煮、气蒸和油洗等方法去掉油腊层,但我们在部队却常看到,当配件油层厚难去时,有的修理和驾驶人员就盲目地用火烧进行启封,问其为什么用火烧时,他们说是既快又省事。实际上这样做是错误的。 配件根据其功用基本上都经过各种不同的热处理,用火烧后往往造成配件机械性能下降,装配后达不到使用要求。常用汽车配件钢材的退火温度约为760～900 Most of the new parts to prevent oxidative rust, are oiled or waxed in paper packaging custody. The use of unsealed, different parts can be used separately boiled, steaming and oil wash and other methods to get rid of wax layer, but we often see in the army, when the thick parts of the oil layer difficult, some repairs and drivers are blind In order to use the fire to unseal, ask why they use the fire, they say it is quick and easy. In fact it is wrong to do so. Parts according to their functions are basically through a variety of different heat treatment, often after the fire caused by parts mechanical properties decline, the assembly up to meet the requirements. Common auto parts steel annealing temperature is about 760 ~ 900
