class="khcont1"><p> 槽鋼的對(duì)接工藝共有五點(diǎn)，下面就來(lái)逐一介紹每一個(gè)步驟： </p> <p> 步：原材料檢驗(yàn)：檢驗(yàn)準(zhǔn)備對(duì)接槽鋼的外形尺寸是否合格，若不合格則需矯正或更換材料。 </p> <p> 第二步：劃線(xiàn)： 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(xiàn)，劃線(xiàn)前應(yīng)滿(mǎn)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(xiàn)的原則是槽鋼的兩翼板上的切割線(xiàn)應(yīng)垂直于腹板，腹板上切割線(xiàn)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(xiàn)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(kāi) 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(xiàn)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(kāi)成對(duì)第六步：注意要點(diǎn)：焊接的話(huà)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。控制焊接后的變形量，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。

/> 布氏硬度的試驗(yàn)原理是將一定直徑的硬質(zhì)合金球施加試驗(yàn)力壓試樣表面，經(jīng)規(guī)定保持時(shí)間后，卸除試驗(yàn)力，測(cè)定試樣表面壓痕的直徑，即可求得布氏硬度值，布氏硬度值的表示：布氏硬度符用98表示。符 96的數(shù)值為硬度值，符后面是按如下順序表示試驗(yàn)條件：①硬質(zhì)合金球直徑;②試驗(yàn)力大小的數(shù)值;③與規(guī)定時(shí)間不同的試驗(yàn)力保持時(shí)間。<br /> 雖然鉬作為合金元素對(duì)奧氏體不銹鋼耐還原性介質(zhì)、耐點(diǎn)腐蝕及縫隙腐蝕的原因尚不完全清楚，但大量實(shí)驗(yàn)已指出。鉬的作用僅當(dāng)鋼中含有較高量的鉻時(shí)才有效。鉬主要是鍍鋅槽鋼中鉻的耐蝕性。 </div><p><img
