實(shí)彎，顧名思義是壓實(shí)了彎折，實(shí)彎時(shí)內(nèi)外輥與管坯內(nèi)外壁雙向壓實(shí)。 </p> <p> (1)實(shí)彎的優(yōu)點(diǎn)是反彈小，成型準(zhǔn)確，而且只要輥型準(zhǔn)確，內(nèi)角成型的R比較準(zhǔn)確。 </p> <p> (2)實(shí)彎的缺點(diǎn)是有拉伸/減薄效應(yīng)。第壹，實(shí)彎會(huì)使彎折處產(chǎn)生拉伸，拉伸效應(yīng)使彎折線縱向的長度縮短;第二，實(shí)彎彎折處金屬會(huì)因拉伸而變薄。 </p> <p> 2、空彎： </p> <p> 空彎是通過外輥與管坯外壁的單向接觸形成彎矩使帶料彎折，空彎會(huì)使彎折線產(chǎn)生壓縮，壓縮效應(yīng)使彎折線縱向伸長，彎折處金屬出現(xiàn)堆積變厚，這就是空彎的壓縮/增厚效應(yīng)。 </p> <p> (1)空彎的優(yōu)點(diǎn)是可以在無法進(jìn)行實(shí)彎時(shí)進(jìn)行邊長的彎折，比如方矩管的上邊/側(cè)邊同步彎折和精整?？諒澾€可以彎折R<0.2t的內(nèi)角而不致管壁發(fā)生斷裂。 </p> <p> (2)空彎的缺點(diǎn)是在上邊/側(cè)邊同步空彎時(shí)，由于上輥和下輥同時(shí)產(chǎn)生壓力，成型力容易超越臨界點(diǎn)，造成邊部失穩(wěn)內(nèi)凹，并且也會(huì)影響到機(jī)組穩(wěn)定運(yùn)行和成型質(zhì)量。這也是方矩管和圓管空彎成型時(shí)不同的特點(diǎn)

</p> <p> (2)硫是鋼中的有害雜質(zhì)。硫含量高的鋼在高溫高壓下加工容易產(chǎn)生裂紋，通常稱為熱脆性。 </p> <p> (3)磷能使鋼的塑性和韌性明顯降低，特別是在低溫下，這種現(xiàn)象稱為冷脆。在優(yōu)質(zhì)鋼中，應(yīng)嚴(yán)格控制硫和磷。另一方面，低碳鋼中硫、磷含量高，易切削，有利于提高鋼的機(jī)械加工性能。 </p> <p> (4)錳;能提高鋼的強(qiáng)度，能削弱和消除硫的不利影響，提高鋼的淬透性。高錳含量的高合金鋼(高錳鋼)具有良好的耐磨性和其他物理性能。 </p> <p> (5)硅;它能提高鋼的硬度，但塑性和韌性降低。電工用鋼中含有一定量的硅，可以改善其軟磁性能。 </p> <p> (6)鎢;能提高鋼的紅硬度和熱強(qiáng)度，提高鋼的耐磨性。 </p> <p> (7)鉻，可以提高鋼的淬透性和耐磨性，提高鋼的耐腐蝕性和抗氧化性。 </p> <p> 為了提高耐腐蝕性，對(duì)普通鋼管(黑管)進(jìn)行鍍鋅處理。鍍鋅鋼管分為熱鍍鋅和電工鋼鍍鋅。熱鍍鋅層厚，鍍鋅成本低，可選用鍍鋅鋼管。 </p><p> 鍍鋅方管淺談其具體有哪些特點(diǎn)？ </p> <p> 1.防腐功能：因?yàn)樗怯蓪こ５暮附臃焦?在它的表面進(jìn)行熱鍍鋅或許冷鍍鋅的工藝進(jìn)行處理的,不妨預(yù)防和空氣直接接觸,如此的話發(fā)生氧化的可能性就會(huì)降低很多,耐腐蝕功能就不妨升高很多. </p> <p>

鋼管鍍鋅前要經(jīng)過鍍前處理酸洗、清洗、沖洗、浸涂溶劑、烘干。焊管由行車吊至酸洗槽中進(jìn)行酸洗(每吊2噸左右)。26%左右的鹽酸溶液進(jìn)行酸洗，為了防止過分酸洗和酸霧揮發(fā)，在酸洗液中添加0.5~1.0g/L的緩蝕劑和抑霧劑，常溫進(jìn)行酸洗，酸洗時(shí)間一般為30~60分鐘，為使鋼管能均勻酸洗，在酸洗過程中采用吊車將鋼管起吊2~3次，以提高酸洗效果。當(dāng)酸液濃度下降至100g/L時(shí)應(yīng)補(bǔ)充或更換，含鐵量達(dá)到220~260g/L作為廢酸排放。酸洗后的鋼管由行車吊至清洗槽進(jìn)行清洗以去除酸洗后積聚在鋼管表面的殘酸和鐵鹽，然后吊至沖洗臺(tái)架用0.7~0.8Mpa的清水沖洗，待水滴干后，將鋼管吊至溶劑槽中浸涂，浸蘸時(shí)間約一分鐘，溶劑采用600~650g/L氯化鋅和80~100g/L氯化銨以及1~2g/L的OP-10表面活性劑。為提高鋼管的溶劑中預(yù)鍍效果，溶劑始終保持弱堿性，然后由行車吊至干燥爐臺(tái)架進(jìn)入干燥爐內(nèi)烘干，烘干溫度100~130度，時(shí)間一般為6~10分鐘。
