一些鍍鋅角鋼在表面上有一些缺陷，例如表面不平整或微小的鋅顆粒。鍍鋅角鋼表面粗糙的原因是什么?濟南興奧偉業(yè)鋼管有限公司，作為鍍鋅角鋼的制造商，當然知道這個的原因，現(xiàn)在它將揭示問題。 </p> <p> 1、預鍍處理產(chǎn)生“過酸洗滌”，對角鋼鍍鋅層的表面粗糙度的影響。 </p> <p> 酸洗后“粗糙化鋼的表面或產(chǎn)生豆痕，這是熱浸鍍鋅后工件表面粗糙的原因之一。 </p> <p> 2、鋅浴溫度過高或浸泡時間過長，影響角鋼鍍鋅層的表面粗糙度。 </p> <p> 當鋅浴溫度過高時，鋅浸漬時間過長，或者由于角鋼成分和Saint-Delin效應的影響，Zn-Fe合金相過多或不均勻，表面粗糙度為也造成了。鍍鋅層越厚，表面越粗糙。 </p> <p> 從鋅液中取出后，熱浸鍍鋅角鋼緩慢冷卻，或者鋼部分過厚，或者在熱浸鍍鋅后不立即堆積角鋼，并且可能發(fā)生表面粗糙。

磁感應強度BT在磁介質(zhì)中的磁化，可以看作在原先的磁場強度（H）上再加上一個由磁化強度（J）所決定的，數(shù)量等于4J的新磁場，因而在磁介質(zhì)中的磁場B=H+4J的新磁場，叫做磁感應強度。磁場強度HA/m導體中通過電流，其周圍就產(chǎn)生磁場。<br /> 磁場對原磁矩或電生作的大小為磁場強度的表征。矯頑力HcA/m樣品磁化到飽和后，由于有磁滯現(xiàn)象，欲使磁感應強度減為零，須施加一定的負磁場Hc，Hc就稱為矯頑力。鐵損PW/kg鐵磁材料在動態(tài)磁化條件下，由于磁滯和渦流效應所消耗的能量。 </div><p><img
