鍍鋅方管的處理工藝：鍍鋅帶方管除油的要津形式是在堿性的環(huán)境下采用化學(xué)除油和電化學(xué)除油；如果需要增加除油效果還要加入活性劑和乳化劑，根據(jù)鍍鋅帶鋼的油污狀況和程度以及當(dāng)時的溫度和堿液的濃度，適當(dāng)?shù)脑黾踊驕p少除油的時間。 </p> <p> 鍍鋅帶方管油后必須進(jìn)行徹底的水洗，以避免堿液或者油污進(jìn)入除銹液。對于體積較小的鍍鋅帶鋼，一般采用的是化學(xué)除銹。 </p> <p> 鍍鋅方管要想分到細(xì)分市場，應(yīng)增強(qiáng)品牌意識，加大品牌建設(shè)的投入，提升鍍鋅帶鋼品牌的拉伸力，鍍鋅帶方管讓品牌吸引消費(fèi)者，用產(chǎn)品留住消費(fèi)者，這樣才能真正在白熱化的市場中成功突圍。昆明熱鍍鋅方管經(jīng)銷商熱鍍鋅方管廠家直銷，云南贛僑鋼材廠家供應(yīng)。</p><div

熱鍍鋅方管易出現(xiàn)折疊。折疊是熱鍍鋅方管表面形成的各種折線，這種缺陷往往貫穿整個產(chǎn)品的縱向。產(chǎn)生折疊的原因是由于廠家追求高效率，壓下量偏大，產(chǎn)生耳子，下一道軋制時就產(chǎn)生折疊，折疊的產(chǎn)品折彎后就會開裂，鋼材的強(qiáng)度大下降。 </p> <p> 熱鍍鋅方管外表經(jīng)常有麻面現(xiàn)象。麻面是由于軋槽磨損嚴(yán)重引起鋼材表面不規(guī)則的凹凸不平的缺陷。由于熱鍍鋅方管廠家要追求利潤，經(jīng)常出現(xiàn)軋槽軋制超標(biāo)。 </p> <p> 熱鍍鋅方管表面易產(chǎn)生結(jié)疤。原因有兩點(diǎn)：(1)．熱鍍鋅方管材質(zhì)不均勻，雜質(zhì)多。(2)。廠家導(dǎo)衛(wèi)設(shè)備簡陋，容易粘鋼，這些雜質(zhì) </p> <p> 材表面易產(chǎn)生裂紋，原因是它的坯料是土坯，土坯氣孔多，土坯在冷卻的過程中由于受到熱應(yīng)力的作用，產(chǎn)生裂痕，經(jīng)過軋制后就有裂紋。 </p> <p> 熱鍍鋅方管容易刮傷，原因是熱鍍鋅方管廠家設(shè)備簡陋，易產(chǎn)生毛刺，刮傷鋼材表面。深度刮傷降低鋼材的強(qiáng)度。 </p> <p> 熱鍍鋅方管無金屬光澤，呈淡紅色或原因有兩點(diǎn)二、它的坯料是土坯。材軋制的溫度不標(biāo)準(zhǔn)，他們的鋼溫是通過目測的，這樣無法按規(guī)定的奧氏體區(qū)域進(jìn)行軋制，鋼材的性能自然就無法達(dá)標(biāo)。 </p> <p> 熱鍍鋅方管的橫筋細(xì)而低，經(jīng)常出現(xiàn)充不滿的現(xiàn)象，原因是廠家為大的負(fù)公差，成品前幾道的壓 </p> <p> <br /> </p><p> 檢測熱鍍鋅方管表面缺陷的方法： </p> <p> 磁粉法檢測：磁粉法檢測的原理是在方管材料中實(shí)現(xiàn)磁場，根據(jù)缺陷處的漏磁場與磁粉的相互作用，當(dāng)表面和近表面有不連續(xù)或缺陷時，則在不連續(xù)處或缺陷處磁力線發(fā)生局部畸變產(chǎn)生磁極。其優(yōu)點(diǎn)是設(shè)備投資少，可靠性高，具有直觀性。缺點(diǎn)是操作成本高，不能對缺陷準(zhǔn)確分類，檢測速度較低。 </p> <p> 四紅外線檢測：通過高頻感應(yīng)線圈，在方管表面產(chǎn)生感應(yīng)電流，感應(yīng)電流會導(dǎo)致缺陷區(qū)域消耗更多電能，引起局部溫度升高，通過紅外線檢測局部溫度，從而確定缺陷深度。紅外線檢測一般用于平直表面的缺陷檢測，不適合檢測表面不平整金屬。 </p> <p> 漏磁檢測：方管的漏磁檢測方法和磁粉檢測方法非常相似，適用范圍、靈敏度和可靠性較磁粉檢測方法更強(qiáng)。鍍鋅方管管體與插接法蘭間的連接應(yīng)采用無鉚釘連接工藝，運(yùn)用進(jìn)口設(shè)備進(jìn)行無鉚釘連接工藝。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
