第二步：劃線： a) 根據(jù)對(duì)接后的長(zhǎng)度尺寸，在準(zhǔn)備對(duì)接的角鋼上劃線，劃線前應(yīng)滿足兩個(gè)要求： ⑴、保證對(duì)接槽鋼的小長(zhǎng)度要大于200mm。 ⑵、長(zhǎng)度方向上應(yīng)留有2~3mm的余量。 b) 劃線的原則是槽鋼的兩翼板上的切割線應(yīng)垂直于腹板，腹板上切割線應(yīng)成45°夾角。如下圖 </p> <p> 第三步：切割：用半自動(dòng)火焰切割機(jī)沿劃線下料，下料后用半自動(dòng)火焰切割機(jī)或砂輪機(jī)在槽鋼內(nèi)側(cè)面開 45°單V形坡口。切割面應(yīng)光滑平整，無(wú)缺口。 </p> <p> 第四步：拼裝：拼裝前把兩根準(zhǔn)備拼裝的槽鋼倒扣于平臺(tái)上，然后調(diào)整兩槽鋼的直線度及間隙，點(diǎn)焊固定。 </p> <p> 第五步：焊接：采用氣體保護(hù)焊（GMAW）焊接，為減少焊接變形，焊前應(yīng)將槽鋼成對(duì)背靠背點(diǎn)焊在一起，先焊翼板上的坡口側(cè)，然后焊接腹板的坡口，坡口側(cè)焊接完成后。打開成對(duì)第六步：注意要點(diǎn)：焊接的話主要是擔(dān)心焊不牢和焊接應(yīng)力過(guò)大。型鋼的壁厚較薄，對(duì)焊本身就是不可靠的。所以，可以在對(duì)接處加襯板，用角焊縫焊接?？刂坪附雍蟮淖冃瘟?，你可以采用剛性固定進(jìn)行焊接，這樣可以避免變形。工藝上注意減小應(yīng)力。用螺栓連接也需要襯板，要注意螺栓的大小、數(shù)量和間距。還要計(jì)算型鋼本身的薄壁是否會(huì)被壓潰，解決的方法是焊塊貼板，再鉆螺栓孔。原則就是，對(duì)接處的強(qiáng)度不弱于其它部位，且沒(méi)有較大應(yīng)力。

耐腐蝕性：316L不銹鋼槽鋼具有與不穩(wěn)定的鎳鉻合金304相似的抵擋一般腐蝕的能力。在碳化鉻程度的溫度范圍中的長(zhǎng)時(shí)間加熱可能會(huì)影響合金321和347在惡劣的腐蝕介質(zhì)中的。主要用于高溫應(yīng)用，高溫應(yīng)用要求材料有強(qiáng)的抗敏化性，以防止在較低溫度的粒間腐蝕。<br /> 316L不銹鋼槽鋼的高溫抗氧化性：316L不銹鋼槽鋼都具有高溫抗氧化性，但是，氧化率會(huì)受暴露環(huán)境以及產(chǎn)品形態(tài)等固有因素的影響。<br /> 316L不銹鋼槽鋼的物理性能：金屬的總傳熱系數(shù)除了取決于金屬的導(dǎo)熱系數(shù)外，還取決于其它因素。在大多數(shù)情況下，膜層散熱系數(shù)、銹皮和金屬的表面狀況。不銹鋼能保持表面整潔，因此它的傳熱性比其它導(dǎo)熱系數(shù)更高的金屬更好。<br /> 316L不銹鋼槽鋼加熱到850～1250℃，然后進(jìn)行以1℃/s以上的冷卻速度冷卻的熱處理。這樣可以成為含體積分?jǐn)?shù)12%以上馬氏體的組織、730MPa以上的高強(qiáng)度、耐蝕性和彎曲加工性能、焊接熱影響區(qū)韌性優(yōu)良的高強(qiáng)度鍍鋅槽鋼。再利用含Mo、B等，可以顯著提高焊接部位的沖壓加工性能。 </p> <p> </p>

冶煉耐熱鋼一般在電弧爐或感應(yīng)爐中熔煉。要求高的往往采用真空精煉和爐外精煉工藝。鑄造某些高合金耐熱鋼難以加工變形，生產(chǎn)鑄件不僅比軋材合算，而且鑄件還有較高的持久強(qiáng)度。所以在耐熱鋼中耐熱鑄鋼占有相當(dāng)大的比例。<br /> 鑄造除采用砂型鑄造外，還可用精密鑄造工藝以表面光滑、尺寸的產(chǎn)品。對(duì)合成氨和裂解用的高溫爐管往往采用離心鑄造的。熱處理珠光體熱強(qiáng)鋼通常經(jīng)正火或調(diào)質(zhì)后使用;馬氏體耐熱鋼用調(diào)質(zhì)處理，以組織，良好的綜合力學(xué)性能和高溫強(qiáng)度。 </div><p><img

如何識(shí)別304不銹鋼槽鋼的真假<br /> 一、304不銹鋼槽鋼的磁性試驗(yàn)<br /> 304不銹鋼槽鋼磁性試驗(yàn)是區(qū)別退火奧氏體不銹鋼與鐵素體不銹鋼的***簡(jiǎn)單的方法。奧氏體不銹鋼是非磁性鋼，但經(jīng)大壓下冷加工后將具有輕度的磁性;而純粹的鉻鋼和低合金鋼都是強(qiáng)磁性鋼。當(dāng)然材質(zhì)不同效果也是不同的，就像304不銹鋼槽鋼和316不銹鋼槽鋼的磁性就偏小，201不銹鋼槽鋼磁性相比較來(lái)說(shuō)偏大些。<br /> 二、304不銹鋼槽鋼的硝酸點(diǎn)試驗(yàn)<br /> 304不銹鋼槽鋼的一個(gè)顯著特點(diǎn)是對(duì)濃硝酸和稀硝酸具有固有的耐蝕性。這種性能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。但高碳型420和440鋼在進(jìn)行硝酸點(diǎn)試驗(yàn)時(shí)則稍受腐蝕，有色金屬遇到濃硝酸時(shí)立即會(huì)被腐蝕。而稀硝酸對(duì)碳鋼具有強(qiáng)烈的腐蝕性。<br /> 三、304不銹鋼槽鋼的硫酸銅點(diǎn)試驗(yàn)<br /> 硫酸銅點(diǎn)試驗(yàn)是快速區(qū)分普通碳素鋼和所有類型的不銹鋼管的***簡(jiǎn)便方法。所使用的硫酸銅溶液的濃度為5~10%。在進(jìn)行點(diǎn)試驗(yàn)前，試驗(yàn)區(qū)應(yīng)徹底304不銹鋼槽鋼表面的油脂或各種雜質(zhì)，并用軟磨布磨光一個(gè)小區(qū)域，然后再用滴瓶向清理后的區(qū)域滴注硫酸銅溶液。普通碳素鋼或鐵在幾秒鐘內(nèi)就會(huì)形成一層表面金屬銅，而304不銹鋼槽鋼的表面則不產(chǎn)生銅沉淀或顯示銅的顏色。<br /> 四、304不銹鋼槽鋼的硫酸試驗(yàn)<br /> 硫酸浸沒(méi)不銹鋼管試驗(yàn)?zāi)馨?02不銹鋼管和304不銹鋼槽鋼與316不銹鋼槽鋼和317不銹鋼槽鋼區(qū)分開來(lái)。不銹鋼管試樣的切邊應(yīng)經(jīng)過(guò)細(xì)磨，然后在體積濃度為20~30%、溫度為60~66℃的硝酸(比重為1.42)中清洗和鈍化半小時(shí)。硫酸試驗(yàn)溶液的體積濃度為10%，加熱到71℃當(dāng).302不銹鋼槽鋼和304不銹鋼槽鋼浸入這種熱溶液中時(shí)，被迅速腐蝕并產(chǎn)生大量氣泡，試樣在幾分鐘內(nèi)變黑;而316不銹鋼槽鋼和317不銹鋼槽鋼的試樣則不受腐蝕或反應(yīng)很慢(不產(chǎn)生氣泡)，試樣在10~15分鐘內(nèi)不變色。如果采用同時(shí)試驗(yàn)具有已知成分的試樣來(lái)進(jìn)行近似比較的話，可使試驗(yàn)更為準(zhǔn)確。<br /> 以上就是四種304不銹鋼槽鋼真假判定方法，希望可以幫到大家!同時(shí)也建議大家在挑選304不銹鋼槽鋼時(shí)應(yīng)選擇可靠、可信賴的大廠家生產(chǎn)的管材，更有保障，用著也放心!<br /> </div><div id="0mi2m2c" class=imgtipsbox>點(diǎn)擊查看智凱鋼管(昭通市彝良縣分公司)的<a
