-
摘要: 通過對熱軋管、冷拔管內(nèi)表面缺陷的測量、分析,指出了影響缸筒用高精度冷拔管內(nèi)表面質(zhì)量的主要缺陷是麻點,以及減少麻點的具體措施和方法。Abstract: Based on the results of relevant inspection and analysis of the inside surface defects of the hot-rolled and cold-drawn pipes, it is pointed out that the main defect which affects the inside surface quality of the high-precision cold-drawn pipes for cylinder service is the pockmark, and accordingly specific measures to lessen the said defect are also proposed.
