冷鍍鋅方管與熱鍍鋅方管在鍍鋅工藝有很大的差別。冷鍍鋅方管的角棱部位容易產(chǎn)生“電燒”該部位顏色灰暗，鋅層較厚。在陰角部位易形成電流死角產(chǎn)生欠電流區(qū)，該部位鋅層較薄，冷鍍鋅方管內(nèi)壁無鋅層附著。冷鍍鋅方管整體無鋅瘤、結(jié)塊等現(xiàn)象，但整體鋅層較薄，外壁鋅層厚度在5μm-10μm。 </p> <p> 熱鍍鋅方管的內(nèi)壁和外壁均有鋅層附著，會有水紋和少許鋅瘤，但整體鋅層較厚，方管內(nèi)外壁鋅層厚度在70μm以上。所以您在購買冷熱鍍鋅方管時，一定要看清楚是否是自己所需求的產(chǎn)品，不僅從上面的方法區(qū)分，還有從價格上面也是有很大的區(qū)別的，熱鍍鋅方管價格遠(yuǎn)遠(yuǎn)高于冷鍍鋅方管。 </p> 鍍鋅帶方管和bai鍍鋅方管的區(qū)別是耐腐du蝕的時間，鍍鋅帶方管zhi是用熱軋鍍鋅帶鋼制造而成的，鍍鋅方管dao也被稱為熱浸鍍鋅方管，是用黑方管經(jīng)過酸洗再入鋅池上鋅而成，這樣的鍍鋅方管使用年限可長達(dá)二十年，而鍍鋅帶方管經(jīng)過幾場雨水后九有起白點(diǎn)脫皮生銹的現(xiàn)象。</div><p><img

title="值得信賴的鍍鋅方管廠家"><br></p><div id="hyvgdid" class="khcont">方管按生產(chǎn)工藝分：熱軋無縫方管、冷拔無縫方管、擠壓無縫方管、焊接方管。其中焊接方管又分為： (a)按工藝分——電弧焊方管、電阻焊方管(高頻、低頻)、氣焊方管、爐焊方管 (b)按焊縫分——直縫焊方管、螺旋焊方管 2、煉鋼的主要任務(wù)是按所煉鋼種的質(zhì)量要求，調(diào)整鋼中碳和合金元素含量到規(guī)定范圍之內(nèi)，并使 P、S、H、O、N 等雜質(zhì)的含量降至允許限量之下。煉鋼過程實(shí)質(zhì)上是一個氧化過程，爐料中過剩的碳被氧化，燃燒成CO氣體逸出，其它 Si、P、Mn 等氧化后進(jìn)入爐渣中。S 部份進(jìn)入煉渣中，部份則生成 SO2 排出。當(dāng)鋼水成份和溫度達(dá)到工藝要求后，即可出鋼。為了除去鋼中過剩的氧及調(diào)整化學(xué)成份，可以添加脫氧劑和鐵合金或合金元素。 3、初軋模鑄鋼錠采取熱裝、熱送新工藝，進(jìn)入均熱爐加熱，然后通過初軋機(jī)及鋼坯連軋機(jī)軋成板坯、管坯、小方坯等初軋產(chǎn)品，經(jīng)過切頭、切尾、表面清理，(火焰清理、打磨)高品質(zhì)產(chǎn)品則還需對初軋坯進(jìn)行扒皮和探傷，檢驗(yàn)合格后入庫。目前初軋廠的產(chǎn)品有初軋板坯、軋制方坯、氧氣瓶用鋼坯、齒輪用圓管坯、鐵路車輛用車軸坯及塑模用鋼等。 4、轉(zhuǎn)爐煉鋼簡介，從車運(yùn)來的鐵水經(jīng)過脫硫、擋渣等處理后即可倒入轉(zhuǎn)爐中作為主要爐料，另加 10% 以下的廢鋼。然后，向轉(zhuǎn)爐內(nèi)吹氧燃燒，鐵水中的過量碳被氧化并放出大量熱量，當(dāng)探頭測得達(dá)到預(yù)定的低碳含量時，即停止吹氧并出鋼。一般在鋼包中需進(jìn)行脫氧及調(diào)整成份操作;然后在鋼液表面拋上碳化稻殼防止鋼水被氧化，即可送往連鑄或模鑄工區(qū)。對要求高的鋼種可增加底吹氬、RH 真空處理、噴粉處理(噴 SI—CA 粉及變性石灰)可以有效降低鋼中的氣體與夾雜，并有進(jìn)一步降碳及降硫的作用。在這些爐外精煉措施后還可以終微調(diào)成份，滿足優(yōu)質(zhì)無縫方管等鋼材的需求。</div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/193/1357/202402220658384913.jpg"
