釆用均匀设计法研究了药皮中大理石、萤石以及大理石和石英交互作用对FV520(B)不锈钢焊条的发红性、脱渣性以及飞溅性的影响。结果表明:随着焊条药皮中萤石含量的增加,FV520(B)焊条的发红程度增大,且脱渣性变差,但飞溅减小;随着药皮中大理石含量的增加,FV520(B)焊条的发红程度先减小后再增大,而脱渣性是先变好后又变差,飞溅则是逐渐增大。而药皮中大理石和石英比值的增大使得FV520(B)焊条的发红程度先增大后减小,当其比值为6.14时,焊条的发红程度最大;焊条的脱渣性随着比值的增大先逐渐变好后再变差;而飞溅则是随比值的增大而增大。
Uniform design method was used to study the influence of the interaction of marble, fluorite, marble and quartz in the coating on the redness, detachability and splashing of FV520 (B) stainless steel electrode. The results showed that with the increase of fluorite content in electrode coating, the degree of redness of FV520 (B) electrode increased, and the deslagging property deteriorated but the spatter decreased. With the increase of marble content in the coating, FV520 (B) The redness of the electrode first decreases and then increases, while the deslagging property is deteriorated after the first change and the splash is gradually increased. The increase of the ratio of marble and quartz in the coating made the degree of redness of FV520 (B) electrode first increase and then decrease, and the redness of electrode was the largest when the ratio was 6.14. Of the first increase gradually worse and then worse; while the splash is with the increase of the ratio increases.
