Effect of Coating Component on Process Performance of FV520(B) Electrode
By uniform design method, the marble, fluorite and marble and quartz in the interaction on FV520(B) stainless steel was studied with alkaline electrode redness, off the slag and spatter performance. The results show that with the increase of the content of fluorite in electrode coating, the degree of redness on FV520(B) electrode increases, and the deslag is more worse, but splash decreases. With the increase of the content of marble, the degree of redness increases first and then decreases, the opposite is for deslagging, while splash increases gradually. And the increase of marble and quartz ratio in electrode makes the red degree of FV520(B) electrode decrease again after first rise. When the ratio is 6.14, the redness of electrode is worst. The slag increases then decrease along with the increase of the ratio gradually, and the splash increases along with the increase of ratio.
