“焊接”創刊号上陈武卿工程师所写的“三种国产低碳鋼焊条的制造”的文章中,提到UM—7焊条的熔渣是碱性的,并且在不少文献和資料中也會經提到过这种看法。作者具有不同的意見。大家知道,Mn0-SiO_2FeO渣系作为焊条制造配方的指南,在国內外是十分普遍的。因此对于MnO-SiO_2FeO渣系中具有代表性的,UM—7焊条的属性的研究是十分重要的,这对今后进一步发展和利用这个渣系具有重要意义。
In the article “Manufacture of Three Domestic Low Carbon Steel Welding Rods” written by Chen Wuqing on the first issue of “Welding”, it is mentioned that the slag of UM-7 electrode is alkaline and will be found in many documents and materials Having mentioned this view. The author has a different opinion. As we all know, Mn0-SiO2FeO slag system as a guide to manufacturing formulations, is very common at home and abroad. Therefore, it is very important to study the properties of the UM-7 welding rod in the MnO-SiO 2 FeO slag system, which is of great significance for the further development and utilization of this slag system in the future.
