本研究中，我们开发了一种配套Q460MPa抗震耐蚀耐火钢使用的电焊条及埋弧焊丝+焊剂组合，通过研究微合金元素的配比，使其具备良好的力学性能，满足600℃，3h高温屈服强度大于常温2/3，-40℃冲击韧性大于47J，并且耐蚀性能与母材匹配。该数据为对接头的冷弯性能。弯曲压头直径4ts，弯曲角度180°，正弯完好，反弯有微裂纹。

In this study, we developed a supporting Q460MPa earthquake corrosion resistant refractory steel welding electrode and submerged arc welding wire + flux composition, through the research of micro alloying elements ratio, make its have good mechanical properties, 600 ℃, 3 h high temperature yield strength is greater than the normal temperature two-thirds, and 40 ℃ impact toughness is more than 47 j, and corrosion resistant performance and the parent metal to match. The data is the cold bending performance of the joint. Bending head diameter 4TS, bending Angle 180°, good forward bending, reverse bending with microcracks.
