這種方法一般是采用熱軋疊軋板作為原料，首先把經(jīng)過退火的鋼材送入酸洗車間,用硫酸或鹽酸清理鋼材表面的氧熱鍍鋅法化鐵皮。酸洗之后的鋼材立即進(jìn)入水箱中浸泡等待鍍鋅，這樣可以防止鋼材再氧化。后經(jīng)過酸洗、水清洗、擠干、烘干、進(jìn)入鋅鍋(溫度一直保持在445—465℃)熱鍍鋅，再進(jìn)行涂油和鉻化處理。這種方法生產(chǎn)的熱鍍鋅板比濕法鍍鋅成品質(zhì)量有明顯提高，只對小規(guī)模生產(chǎn)有一定價(jià)值。 </p> <p> 惠林法熱 </p> <p> 該連續(xù)鍍鋅生產(chǎn)線包括堿液脫脂、鹽酸酸洗、水沖洗、涂溶劑、烘干等一系列前處理工序，而且原板進(jìn)入鍍鋅線鍍鋅前還需要進(jìn)行罩式爐退火。這種方法生產(chǎn)工藝復(fù)雜，生產(chǎn)成本高，更為主要的是此方法生產(chǎn)的產(chǎn)品常常帶有溶劑缺點(diǎn)，影響鍍層的耐蝕性。并且鋅鍋中的AL常常和鋼材表面的溶劑發(fā)生作用生成三氯化鋁而耗掉，鍍層的粘附性變壞。因而此方法雖然已問世近三十年，但在世界熱鍍鋅行業(yè)中并未得到發(fā)展。昆明質(zhì)量鍍鋅圓鋼廠家供應(yīng)熱鍍鋅圓鋼作是一種典型的不銹鋼棒材，它已經(jīng)被運(yùn)用到各行各業(yè)。</p><div

style="text-indent:25px">云南鍍鋅圓鋼，云南貿(mào)軒商貿(mào)有限公司。盤龍區(qū)鍍鋅圓鋼</p><p> 熱鍍鋅圓鋼的原理分析 </p> <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(gè)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(shí)間，這個(gè)過程稱為時(shí)效處理。 </p> <p> 三、冷拉后時(shí)效處理的鋼筋，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(shí)效過程中內(nèi)應(yīng)力的消減，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。盤龍區(qū)鍍鋅圓鋼</p><p
