经过大量试验,研究出一种新型润滑剂X油,在铝管拉拔润滑过程中的润滑性、退火后的挥发性、易清洗等均好于65~#汽缸油,利于提高管材的表面质量和产品合格率,会有好的经济效益。并通过热重分析试验,对铝管退火后表面形成残焦的原因进行了论证。 After a large number of tests, a new lubricant X oil was developed, which is better than 65 ~ # cylinder oil in the lubrication of drawing and lubrication of aluminum tubes, the volatility after annealing, easy cleaning, etc., which is beneficial to improve the surface quality of the pipe And product qualification rate, there will be good economic benefits. The reason of residual coke formation on the surface of the annealed aluminum tube was demonstrated by TG analysis.
