通過(guò)這一段時(shí)間的了解，相信大家對(duì)硅碳棒已經(jīng)是不陌生了，但對(duì)于想進(jìn)一步了解本產(chǎn)品的相關(guān)知識(shí)的客戶來(lái)說(shuō)這些內(nèi)容還是不夠的。小編就將關(guān)于硅碳棒的選擇原則方面的知識(shí)與大家分享一下，希望引起大家的重視，讓大家對(duì)硅碳棒有一個(gè)深層次的了解。這樣大家在購(gòu)買使用硅碳棒時(shí)也能做到心中有數(shù)，不慌不忙，希望對(duì)大家有所啟發(fā)與幫助。選用硅碳棒的幾個(gè)原則有：爐功率計(jì)算、發(fā)熱部總表面積計(jì)算、硅碳棒支數(shù)的計(jì)算、變壓器的選用，一般電爐的功率視爐子保溫性能而定，保溫好的電爐升溫時(shí)間和散熱時(shí)間要就一些，發(fā)熱面積的計(jì)算就是爐用功率和發(fā)熱部表面負(fù)荷，根據(jù)所有設(shè)計(jì)電爐的各部位尺寸和發(fā)熱部總表面積，從硅碳棒尺寸表中查出所需規(guī)格，選定直徑和長(zhǎng)度，計(jì)算出單支硅碳棒的發(fā)熱部表面積，用所需發(fā)熱部總面積除以單支硅碳棒的發(fā)熱部表面積，就可以求得所需支數(shù)，如果在三相電路中，選用總為3的倍數(shù)，單相電路中應(yīng)為2的倍數(shù)，就是變壓器的選用，硅碳棒的接線方式和變壓器的選擇對(duì)其使用壽命有重要的影響，以上所述基本是硅碳棒廠在考量及選用硅碳棒時(shí)比較注意的幾點(diǎn)。</p><p
