本文分析了钛钙型立向下电焊条的主要冶金特点。通过正交设计及实验工作,以及对焊条的工艺性能进行全面评定和对焊条熔敷金属机械性能的测定,确定了钛钙型立向下电焊条的最佳配方。本文还将日本的“ZERODE—6V”(低氢型)、瑞典ESAB公司产的“OK”牌下行焊条,湘潭大学的J422下行焊条与我们研制的钛钙型立向下电焊条的药皮熔化温度区间进行了测定比较。 This paper analyzes the main characteristics of titanium-calcium vertical down welding electrode. By orthogonal design and experimental work, as well as the comprehensive evaluation of the process performance of the electrode and the determination of the mechanical properties of the electrodeposited metal, the optimal formulation of the titanium calcium vertical down welding electrode was determined. In this paper, the “ZERODE-6V” (low hydrogen type) in Japan, the “OK” brand descending electrode made by Sweden ESAB Company, the J422 descending electrode in Xiangtan University and the titanomagnet vertical welding electrode we developed have been melted Temperature intervals were measured and compared.
