熱鍍鋅----又稱為熱浸鍍鋅，他是在高溫下把鋅錠融化，在放入一些輔助材料，然后把金屬結(jié)構(gòu)件浸入鍍鋅槽中，使金屬構(gòu)件上附著一層鋅層。熱鍍鋅的優(yōu)點(diǎn)在于他的防腐能力強(qiáng)，鍍鋅層的附著力和硬度較好。產(chǎn)品鍍鋅后重量有所增加，我們常說(shuō)的上鋅量，也主要是針對(duì)熱鍍鋅來(lái)說(shuō)的。 </p> <p>

當(dāng)熱鍍鋅圓鋼負(fù)載扁鋼厚度不小于5mm時(shí)，鍍鋅厚的平均鋅層重量不小于610g/m2;當(dāng)負(fù)載扁鋼厚度小于5mm時(shí)，鋅層后的平均鋅層重量不小于460g/m2。由于黑件經(jīng)過(guò)酸洗后會(huì)去除表面的銹蝕層，所以經(jīng)過(guò)鍍鋅后并不會(huì)增加扁鋼的厚度，這一點(diǎn)采購(gòu)商要注意，不能以此作為扁鋼是否符合要求的標(biāo)準(zhǔn)。 </p> <p> 熱鍍鋅圓鋼上鋅量的多少，直接影響鋼格板的使用壽命，也是用戶關(guān)心的問(wèn)題。鍍鋅后質(zhì)量及要求必須符合中國(guó)GB/T13912規(guī)定。熱鍍鋅圓鋼的上鋅量根據(jù)熱鍍鋅圓鋼的扁鋼厚度而言。昆明質(zhì)量鍍鋅圓鋼廠云南鍍鋅圓鋼，云南貿(mào)軒商貿(mào)有限公司。</p><div

鍍鋅圓鋼是指截面為圓形的實(shí)心長(zhǎng)條鋼材。其規(guī)格以直徑的毫米數(shù)表示，如"50"即表示直徑為50毫米的圓鋼。圓鋼分為熱軋、鍛制和冷拉三種。熱軋圓鋼的規(guī)格為5.5-250毫米。其中：5.5-25毫米的小圓鋼大多以直條成捆供應(yīng)，常用作鋼筋、螺栓及各種機(jī)械零件；大于25毫米的圓鋼，主要用于制造機(jī)械零件或作無(wú)縫鋼管坯，圓鋼與其它鋼筋的區(qū)別：外型不一樣，圓鋼外型光圓，無(wú)紋無(wú)肋，其它鋼筋表面外型有刻紋或有肋，這樣就造成圓鋼與混凝土的粘結(jié)力小，而其它鋼筋與混凝土的粘結(jié)力大。成份不一樣，圓鋼(一級(jí)鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。 </p>鍍鋅圓鋼的性能優(yōu)勢(shì) <p> 圓鋼冷拉后，其表層不可有裂痕和部分縮頸。冷拔實(shí)驗(yàn)后，冷拉圓鋼的外型不可有裂紋、鱗落或破裂問(wèn)題。、、、 </p> <p> 1、冷拔圓鋼具備淬透性好、強(qiáng)度高、耐磨性能好、調(diào)質(zhì)處理形變小等優(yōu)勢(shì)，常見(jiàn)于制做承擔(dān)重負(fù)載、生產(chǎn)制造大批量大、樣子繁雜的冷作磨具。但該Q345B低合金圓鋼在應(yīng)用全過(guò)程中非常容易出現(xiàn)延性大等難題?？茖W(xué)研究說(shuō)明，改進(jìn)Q345B低合金圓鋼中碳化物的形狀和遍布可合理改進(jìn)原材料延展性。

其次，硝酸點(diǎn)試法也能測(cè)出熱鍍鋅圓鋼材質(zhì)的好壞，若是質(zhì)量不銹鋼的話，它對(duì)濃硝酸和稀硝酸都具有固有的耐蝕性，使其能很容易地從大多數(shù)其他金屬或合金中加以區(qū)分。但若是熱鍍鋅圓鋼是用高碳型鋼制成的，那么它在進(jìn)行硝酸點(diǎn)試時(shí)會(huì)有少量的腐蝕。 </p> <p> 若是有色金屬或是碳鋼制成的熱鍍鋅圓鋼就更明顯了，在進(jìn)行硝酸點(diǎn)試的時(shí)候，前者會(huì)立即被腐蝕，而后者則具有強(qiáng)烈的腐蝕性，使得鋼材受損嚴(yán)重。 </p> <p> 還有類似的檢測(cè)方式是硫酸銅點(diǎn)試法和硫酸試驗(yàn)法，硫酸銅點(diǎn)試是快速區(qū)分普通碳素鋼和所有類型不銹鋼的簡(jiǎn)單有效方法,但是在進(jìn)行點(diǎn)試前，需要將熱鍍鋅圓鋼的試驗(yàn)區(qū)徹底清理油質(zhì)或其它雜質(zhì),并用打磨機(jī)或軟磨布磨光，確保測(cè)試的準(zhǔn)確性。熱鍍鋅圓鋼的工藝流程；昆明質(zhì)量鍍鋅圓鋼廠</p><p

線內(nèi)退火就是由冷軋或熱軋車間直接提供帶卷作為熱鍍鋅的原板，在熱鍍鋅作業(yè)線內(nèi)進(jìn)***體保護(hù)再結(jié)晶退火。屬于這個(gè)類行業(yè)的熱鍍鋅方法包括：森吉米爾法、改良森吉米爾法、美鋼聯(lián)法(同日本川崎法)、賽拉斯法、莎倫法。 </p> <p> 森吉米爾法 </p> <p> 它是把退火工藝和熱鍍鋅工藝聯(lián)合起來(lái)，其線內(nèi)退火主要包括氧化爐，還原爐兩部份組成。帶鋼在氧化爐中煤氣火焰直接加熱到450度左右，把帶鋼表面殘存的軋制油燒掉，凈化表面。后再把帶鋼加熱到700-800度完成再結(jié)晶退火，經(jīng)冷卻段控制進(jìn)鋅鍋前溫度在480度左右，在不接觸空氣的情況下進(jìn)入鋅鍋鍍鋅，因此，森吉米爾法產(chǎn)量高、鍍鋅質(zhì)量較好，此法曾得到廣泛應(yīng)用。昆明質(zhì)量鍍鋅圓鋼廠</p><p
