适于1Cr13NiMoVNb型带极高速堆焊用烧结焊剂的研制

按实际生产的要求,研制一种适合于1Cr13NiMoVNb型带极高速堆焊用的烧结焊剂。经过多次实验,利用正交实验法对数据进行分析,得出了烧结焊剂在要求的焊接工艺规范下各个成分的最佳配合比,用此种焊剂堆焊后焊道的脱渣性好、焊道表面平整光滑,堆焊层中各主要组成元素的百分含量满足要求。最后,对烧结焊剂在焊接过程中的电弧稳定性,焊后的脱渣难易程度、焊道成型情况以及焊道表面的抗氧化性等焊接工艺性进行综合分析,给出了各个组分对焊接综合工艺性的影响趋势。

Preparation of Agglomerated Flux Used for High-speed Strip Surfacing and for Strip of 1Cr13NiMoVNb

According to the actual production, a kind of agglomerated flux , which must be suited to the kind strip of 1Cr13NiMoVNb ,used for strip surfacing was prepared. Through the experiments, making use of orthogonal method, we have made out a conclusion that this kind agglomerated flux has the best match ratio in component which is gotten under the request welding craft norm. After the experiments, the overlay can be taken off very easy ,the surface of welding is very neat and smoothly, the contains of the main elements in the welding surface satisfies the request. At last, analyzing the weldability of the agglomerated flux such as the stability of the arc, taking off the overlay easily or not, and the anti-oxidizes of the surface welding. We describe the trend of influence of the components in the agglomerated flux on the weldability.
