鐵磁材料或工件被適當(dāng)磁化后，在表面或近表面缺點(diǎn)處磁力線發(fā)生局部畸變，逸出工件表面形成磁極，產(chǎn)生漏磁場，吸附施加在工件表面上的磁粉，形成了在合適的觀察條件下目視可見的缺點(diǎn)磁粉圖像（磁痕），磁力線與缺點(diǎn)垂直時(shí)，漏磁場強(qiáng)，也有利于缺點(diǎn)的檢出，而若與缺點(diǎn)平行，則無漏磁場產(chǎn)生，缺點(diǎn)不可能被檢出，故在做磁粉檢測時(shí)。工件要做檢測，找出磁力線與缺點(diǎn)垂直方向，然后對(duì)缺點(diǎn)判定，昆山?jīng)_孔角鋼。 </p> <p> （2）磁粉檢測的優(yōu)點(diǎn) </p> <p> 能直觀的顯示出缺點(diǎn)的位置、形狀、尺寸和嚴(yán)重程度，并靠經(jīng)驗(yàn)大致可以確定缺點(diǎn)的性質(zhì)。靈敏度與工件的大小無關(guān)，線狀表面缺點(diǎn)檢測靈敏度很高。幾乎不受工件的大小和形狀的限制。不僅能檢測鐵磁材料開口于表面的細(xì)小缺點(diǎn)，昆山?jīng)_孔角鋼，沒有開口于表面的近表面缺點(diǎn)在許多情況下也能檢測出來。 </p> <p> （3）磁粉檢測的局限性 </p> <p> 只能檢測表面和近表面缺點(diǎn)，近表面可探測的深度一般在1～2mm。只能顯示缺點(diǎn)的長度，不能確定缺點(diǎn)的埋深和自身的高度。寬而淺的缺點(diǎn)難檢出。磁化場的方向需與缺點(diǎn)主平面相交，夾角應(yīng)在45°～90°，昆山?jīng)_孔角鋼。有時(shí)，還需要從不同方向進(jìn)行多次磁化。

“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> <br /> </p> <p> 二：鋅液溫度過高或浸鋅時(shí)間過長，對(duì)角鋼鍍鋅層表面粗糙的影響。 </p> <p> 鋅液溫度過高、浸鋅時(shí)間過長時(shí)，或由于角鋼成分及圣德林效應(yīng)的影響，使Zn-Fe合金相生成過多或不均勻，也會(huì)造成表面粗糙。鍍鋅層越厚表面越容易顯得粗糙。 </p> <p> 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(huì)出現(xiàn)表面粗糙現(xiàn)象。 </p> <p> <br /> </p> <p> 三：角鋼制造選用鋼材的成分或表面條件，對(duì)角鋼鍍鋅層表面粗糙的影響。 </p> <p> 若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(huì)比原先更平整光滑。 </p> <p> <br /> </p> <p>

無錫鍍鋅角鋼是不銹鋼型材的一種，目前主要應(yīng)用于工業(yè)、建筑業(yè)等行業(yè)的金屬結(jié)構(gòu)設(shè)施上，是將除銹后的鋼件浸入440~460℃左右融化的鋅液中，使鋼構(gòu)件表面附著鋅層，從而起到防腐的目的。這是一種有效的金屬防腐方式，其使用特點(diǎn)主要有以下幾點(diǎn)： </p> <p> (1)具有較厚的致密的純鋅層覆蓋在鋼鐵表面上,它可以避免鋼鐵基體與任何的腐蝕溶液的接觸,保護(hù)鋼基體免受腐蝕。在一般大氣中,鋅層表面形成一層很薄而密實(shí)的氧化鋅層表面,它很難溶于水,故對(duì)鋼基體起著一定保護(hù)作用。如果氧化鋅與大氣中其它成分生成不溶性鋅鹽后,則防蝕作用更理想。無錫市騰越金屬制品有限公司主要銷售工字鋼、角鋼、槽鋼、H型鋼、鍍鋅角鋼、鍍鋅槽鋼、鋼軌等型材。</p><div
