摘要
在焊管生产中，由于焊缝导向辊靠近焊接挤压辊，工作时常受到高频感应电流影响，造成了导向辊和导向片硬度下降、寿命降低。为此，采取以下改进办法：（１）将整体导向片制做成两半部分，中间加绝缘材料，在导向辊轴上加绝缘套；（２）在导向辊两侧和轴肩以及紧固螺母之间加绝缘材料。通过改造，改善了导向辊的工作环境，提高了导向辊的使用寿命。
In the production of welded pipe, because the weld guide rolls are close to the welding squeezing rolls, they are often affected by HF induction current when running For this reason, the guide rolls and guide fin hardness are reduced, and service life becomes short Therefore, The following improvement measures have been taken: 1) The integrated guide fin is made into two parts; in the middle is put in the insulation material, on the shaft of the guide fin is brought into the insulation ring, too 2) At the both sides of the guide fin, between the shaft shoulder and fastening nuts, the insulation materials are all added Through improvement, the working environment of the guide rolls and service life has been greatly bettered
