/></span></h3> <p> <span style="font-size:36px;">中頻電源的使用</span></p> <p> <span style="font-size:22px;">中頻電源關(guān)鍵是使用在管件設(shè)備中的一個(gè)配件，也是主要的配件之一，主要的作用是對(duì)金屬整體進(jìn)行加熱，工件可達(dá)到內(nèi)外一個(gè)溫度范圍。還應(yīng)用于金屬材料的鑄造、沖壓、擠壓、軋制等加工前的加熱。</span></p> <p> <span style="font-size:22px;">由于中頻爐加熱時(shí)間短，加熱時(shí)幾乎沒(méi)有或少量的氧化皮，因此氧化皮造成重量損失小于0.5%，而煤氣爐氧化皮造成重量損失高達(dá)20%，再加上酸洗的損失、浪費(fèi)是很大的。所以使用中頻電源，可以大大提高效益，且維護(hù)容易，減少工人勞動(dòng)強(qiáng)度，便于實(shí)現(xiàn)自動(dòng)化。</span></p> <p> <span style="font-size:22px;">感應(yīng)加熱，由于高頻的集膚效應(yīng)，感應(yīng)電流的密度是從表面到內(nèi)部逐漸減少的。同樣的材料，頻率越高，電流密度從外表面到內(nèi)部減少得越快。</span></p> <p> <span style="font-size:22px;">在熱處理方面的應(yīng)用，利用中頻電流的集膚效應(yīng)來(lái)提高鋼件的機(jī)械性能，使其具有較高的硬度和抗勞累度，對(duì)鋼管來(lái)講，加熱頻率因鋼管的直徑、管壁的厚薄壁一定時(shí)，鋼管直徑愈小，則感應(yīng)加熱的頻率就愈高。</span></p> <p> <span style="font-size:22px;">淬火負(fù)載特點(diǎn)：負(fù)載變化不大，過(guò)流過(guò)壓的機(jī)會(huì)較少，但是起動(dòng)十分頻繁，操作周期短。</span></p> <p> <span style="font-size:22px;">在焊接方面的應(yīng)用：中頻電源可以用于焊接，具焊接速度快，對(duì)周?chē)臒嵊绊懶?，不用酸洗?lái)清除氧化皮優(yōu)點(diǎn)。還可以用于焊接后的去應(yīng)加（回火）方面，可大大提高工效。</span></p> <p> <span style="font-size:22px;">中頻電源的應(yīng)用廣泛，有些應(yīng)用領(lǐng)域正在開(kāi)發(fā)，隨著晶閘管技術(shù)的發(fā)展以及中頻電源應(yīng)用經(jīng)驗(yàn)的不斷積累，晶閘管中頻電源會(huì)有更廣闊的發(fā)展前程.</span></p> <p> <span style="font-size:22px;">隨著世界各地的發(fā)展，我們公司對(duì)管件設(shè)備配帶的中頻電源進(jìn)行改進(jìn)，一是省電，二是噪音小等。</span></p> <div id="geo60wcq" class="float_c news-page fs_14"> <div id="geo60wcq" class="f_l"> 上一篇：<a
