Abstract
In this article, it introduced the structure and working principles of the inside burr removing device hydraulic system of high-frequency longitudinal welded pipe. Some problems occurred in running course of this device were analyzed, such as pressure surge, hard shutdown caused by temperature increase too fast and unstable quality of inside burr removing. This system was reformed. The modified system runs normally, it effectively solves problems of hard shutdown and unstable reinforcement of inside burr, and the effect is good.关键词
