style="text-indent:25px">我們通常了解到的鍍鋅方管其實(shí)就是熱軋或冷軋鍍鋅帶鋼或鍍鋅卷板為坯料經(jīng)冷彎曲加工成型后，然后再通過高頻焊接制成的方形截面形狀尺寸的空心方形的截面型鋼鋼管，還有就是將事先做好的冷彎空心型鋼管再經(jīng)熱浸鍍鋅加工而成的鍍鋅方矩管。矩形管的高頻焊接正是利用交流電的趨膚效應(yīng)和鄰近效應(yīng)，名揚(yáng)不銹鋼方管的形成方法知識(shí)鋼材（帶鋼）經(jīng)滾壓成型后，形成一個(gè)截面斷開的圓形管坯，在管坯內(nèi)靠近感應(yīng)線圈中心附近旋轉(zhuǎn)一個(gè)或一組阻抗器（磁棒），阻抗器與管坯開口處形成一個(gè)電磁感應(yīng)回路，在趨膚效應(yīng)和鄰近效應(yīng)的作用下，管坯開口處邊緣產(chǎn)生強(qiáng)大而集中的熱效應(yīng)，使焊縫邊緣迅速加熱到焊接所需溫度經(jīng)壓輥擠壓后，熔融狀態(tài)的金屬實(shí)現(xiàn)晶間接合，冷卻后形成一條牢固的對(duì)接焊縫。高頻直縫焊接矩形管通過電磁感應(yīng)原理和交流電荷在導(dǎo)體中的趨膚效應(yīng)、鄰近效應(yīng)和渦流熱效應(yīng)，使焊縫邊緣的鋼材局部加熱到熔融狀態(tài)，經(jīng)滾輪的擠壓，使對(duì)接焊縫實(shí)現(xiàn)晶間接合，從而達(dá)到焊縫焊接之目的。</p><p
