content="熱鍍鋅圓鋼的原理分析一、將鋼材于常溫下進(jìn)行冷拉使產(chǎn)生塑性變形，從而提高屈服強(qiáng)度，這個過程稱為冷拉強(qiáng)化。二、冷拉強(qiáng)化的原理：鋼材在塑性變形中晶格的缺點(diǎn)增多，而缺點(diǎn)的晶格嚴(yán)重畸變對晶格進(jìn)一步滑移將起到阻礙作用，故鋼材的屈服點(diǎn)提高，塑性和韌性降低"><meta

<p> 一、將鋼材于常溫下進(jìn)行冷拉使產(chǎn)生塑性變形，從而提高屈服強(qiáng)度，這個過程稱為冷拉強(qiáng)化。 </p> <p> 二、冷拉強(qiáng)化的原理：鋼材在塑性變形中晶格的缺點(diǎn)增多，而缺點(diǎn)的晶格嚴(yán)重畸變對晶格進(jìn)一步滑移將起到阻礙作用，故鋼材的屈服點(diǎn)提高，塑性和韌性降低。由于塑性變形中產(chǎn)生內(nèi)應(yīng)力，故鋼材的彈性模量降低。將經(jīng)過冷拉的鋼筋于常溫下存放15～20d或加熱到100～200℃并保持一定時間，這個過程稱為時效處理。 </p> <p> 三、冷拉后時效處理的鋼筋，昆明質(zhì)量鍍鋅圓鋼廠家直銷，屈服點(diǎn)進(jìn)一步提高，抗拉極限強(qiáng)度也有所增長，塑性繼續(xù)降低。由于時效過程中內(nèi)應(yīng)力的消減，昆明質(zhì)量鍍鋅圓鋼廠家直銷，昆明質(zhì)量鍍鋅圓鋼廠家直銷，故彈性模量可基本恢復(fù)。工地或預(yù)制構(gòu)件廠常利用這一原理，對鋼筋或低碳鋼盤條按一定制度進(jìn)行冷拉或冷拔加工，以提高屈服強(qiáng)度節(jié)約鋼材。鍍鋅圓鋼，云南貿(mào)軒商貿(mào)有限公司。昆明質(zhì)量鍍鋅圓鋼廠家直銷</p><div

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，常見于制做承擔(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)用全過程中非常容易出現(xiàn)延性大等難題?？茖W(xué)研究說明，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。

</p> <p> 圓鋼應(yīng)用前景廣闊，被普遍用于五金，建筑，汽車、造船、石化、機(jī)械、醫(yī)藥、食品、電力、能源、航天等、建筑裝潢。**普遍的普通機(jī)械零件加工，一般的桿類鋼件，CD桿、螺栓、螺母。 </p> <p> 化學(xué)成分：C0.42-0.50Si0.17-0.37Mn0.50-0.80Cr不大于0.25Ni不大于0.30Cu不大于0.25力學(xué)性能：抗拉強(qiáng)度不小于600Mpa，屈服強(qiáng)度不小于355Mpa，延伸率不小于16，斷面收縮率不小于40%，沖擊功不小于31J。未熱下HBS10/3000不大于229.推薦熱處理溫度：正火850攝氏度。淬火840攝氏度，回火600攝氏度。 </p><p> 熱鍍鋅圓鋼的工藝流程分析，如下： </p> <p> 線外退火 </p> <p> 線外退火就是熱軋或冷軋鋼進(jìn)入熱鍍鋅作業(yè)線之前，首先在抽底式退火爐或罩式退火爐中進(jìn)行再結(jié)晶退火，這樣，鍍鋅線就不存在退火工序了。鋼材在熱鍍鋅之前必須保持一個無氧化物和其他臟物存在的潔凈的純鐵活性表面。這種方法是先由酸洗的方法把經(jīng)退火的表面氧化鐵皮清理，然后涂上一層由氯化鋅或由氯化銨和氯化鋅混合組成的溶劑進(jìn)行保護(hù)，從而防止鋼材再被氧化。 </p> <p> 濕法熱鍍鋅 </p> <p> 鋼材表面的溶劑不經(jīng)烘干(即表面還是濕的)就進(jìn)入起表面覆蓋有熔融態(tài)溶劑的鋅液進(jìn)行熱鍍鋅。此方法的缺點(diǎn)是： </p> <p> a.只能在無鉛狀態(tài)下鍍鋅，鍍層的合金層很厚且粘附性很壞; </p> <p> b.生成的鋅渣都積存在鋅液和鉛液的界面處而不能沉積鍋底(因?yàn)殇\渣的比重大于鋅液而小于鉛液)，這樣鋼材因穿過鋅層污染了表面。 </p> <p> 因此，濕法熱鍍鋅已基本被淘汰。熱鍍鋅圓鋼的材質(zhì)檢測是怎樣的？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
