鍍前處理過程中產(chǎn)生"過酸洗",對角鋼鍍鋅層表面粗糙的影響。 </p> <p> 過酸洗"使鋼材表面粗糙或產(chǎn)生豆痕,這也是工件熱鍍鋅后表面粗糙的原因之一。 </p> <p> 鋅液溫度過高或浸鋅時間過長,對鍍鋅角鋼鍍鋅層表面粗糙的影響。 </p> <p> 鋅液溫度過高,浸鋅時間過長時,或由于角鋼成分及圣德林效應的影響,使Zn-Fe合金相生成過多或不均勻,也會造成表面粗糙.鍍鋅層越厚表面越容易顯得粗糙.熱鍍鋅角鋼從鋅液中取出后冷卻緩慢,或鋼材截面太厚,或熱鍍鋅后角鋼不加隔離立即疊放等原因,也會出現(xiàn)表面粗糙現(xiàn)象。 </p> <p> 角鋼制造選用鋼材的成分或表面條件,對角鋼鍍鋅層表面粗糙的影響。 </p> <p> 其實鍍鋅層表面的光滑與粗糙,是相對而言的.與鋼板,鋼管或鋼絲的"連續(xù)熱鍍鋅"不同,鍍鋅角鋼熱鍍鋅屬于批量熱鍍鋅工藝范疇,鍍鋅層不經(jīng)氣刀吹抹.若熱鍍鋅角鋼所用鋼材表面原本就粗糙不平,有銹蝕坑或明顯的軋制條紋,熱鍍鋅完成后,其表面一般不會比原先更平整光滑。 </p> <br /> </div><p><img
