src="https://tyunfile.71360.com/UploadFile/zbwuzi/637238607270019531/6835560.jpg"></div><p>硅碳棒在生產(chǎn)時，要使用各種粒度經(jīng)過一定比例混合的碳化硅顆粒，為什么不使用統(tǒng)一粒度的碳化硅顆粒呢？若使用統(tǒng)一較大顆粒的碳化硅，堆積密度不夠高，會造成硅碳棒內(nèi)有大量小孔，這樣的硅碳棒整體性不好，不結(jié)實還更容易氧化。若統(tǒng)一使用較小粒度的碳化硅顆粒，生產(chǎn)的硅碳棒強度不會太好，生產(chǎn)難度會更大，所消耗的電量更大，容易出現(xiàn)各種問題，比如燒結(jié)不完全、彎曲等。各個硅碳棒生產(chǎn)廠家在生產(chǎn)硅碳棒時所使用的比例碳化硅可能有略微的差異，因為設(shè)備和環(huán)境都不相同。如果要從外觀上判斷硅碳棒的質(zhì)量好壞是可以嘗試的，建議使用不能用的舊棒，折斷后看一下棒的斷面是否光滑、整體性是否比較強。不光滑整體性不好的可能是燒結(jié)不夠完全也可能是顆粒粒度配合沒有掌握好。這樣的硅碳棒使用起來強度不夠高，抗氧化性能也不好。福建硅鉬棒廠奧翔硅碳設(shè)備的引進更加豐富了公司的設(shè)備品種，為用戶提供了更多的選擇空間。</p><div
