管模埋弧堆焊用合金管丝
摘要：
本发明属焊接技术领域，具体为一种管模埋弧堆焊用合金管丝。由组分C、Mn、Si、Cr、Mo、Nb和Fe等按适当的重量比例经冷轧工艺制备而成。该焊丝与焊剂HJ－260配套使用，具有优良机械性能，其特点是含碳量比较低，硬度不高，便于管模使用前打点处理，而其耐磨性能、抗疲劳性能、抗高温氧化腐蚀性能十分良好。使用该材料堆焊的管模，其使用寿命明显提高。
摘要（英）：

The present invention belongs to the field of welding technology, and is especially one kind of tubular alloy welding wire for submerged-arc pile-up welding of tube mold. The tubular alloy welding wire is prepared with C, Mn, Si, Cr, Mo, Nb, Fe, etc in certain weight proportion and through a cold rolling process. The welding wire is used together with HJ-260 welding flux, and has excellent mechanical performance, low carbon content, mild hardness for pre-treatment of tube mold, and excellent wear, fatigue, high temperature oxidation resisting performance and capacity of increasing the service life of the tube mold.
