金屬硅質量的標準怎樣評判?

發布:安陽坤鑫達冶金耐材有限公司瀏覽:1299次

  對于消費者來說,他們想購買質量合格的金屬硅,作為一家硅金屬制造商,只有保證金屬硅的質量,才能贏得更多用戶的關注,得到良好的發展。因此,無論是消費者還是制造商都非常關注硅金屬的質量。那么判斷金屬硅質量的標準是什么呢?


金屬硅


  1、金屬硅中的硫:硫是生鐵冶煉中的有害雜質之一,降低了生鐵的質量。生鐵中硫含量大于0.07%為廢鐵。高爐爐料帶入爐內的硫有11%來自礦石,3.5%來自石灰石,82.5%來自金屬硅,因此金屬硅是爐料中硫的主要來源。金屬硅的硫含量直接影響高爐的生產。當金屬硅硫含量大于1.6%時,硫含量每增加0.1%,金屬硅用量增加1.8%,石灰石添加量增加3.7%,礦石添加量增加0.3%,高爐產量下降1.5-2.0%。冶金焦硫含量不大于1%,大中型高爐用冶金焦硫含量小于0.4~0.7%。

  2、金屬硅中的磷:煉鐵用冶金焦中磷的含量應小于0.02-0.03%。

  3、金屬硅灰分:金屬硅灰分對高爐冶煉有顯著影響。因此,有必要降低金屬硅的灰分含量。

  4、金屬硅揮發物:金屬硅的成熟度可根據金屬硅揮發物的含量來確定。揮發分大于1.5%表示結焦;揮發分小于0.5-0.7%表示過熱,成熟冶金焦揮發分約為1%。

  5、金屬硅中的水分:水分波動會導致金屬硅測量不準確,從而引起爐況波動。此外,金屬硅水分的增加會使M40升高,M10降低,從而給轉鼓指標帶來誤差。

  6、金屬硅的篩分成分:金屬硅的粒度在高爐冶煉中也很重要。過去,我國對金屬硅晶粒度的要求是:大型焦爐(1300-2000平方米)用金屬硅晶粒度在40毫米以上;中小高金屬硅晶粒度在25毫米以上。金屬硅的粒徑為40-25mm。大于80mm的金屬硅應為整體,使其粒徑范圍變化不大。這樣,硅塊均勻,間隙大,電阻小,爐子運行良好。

  這些是測量金屬硅質量的標準。希望您能迅速準確地辨別出金屬硅的質量是否合格,從而保護自己的權益。坤鑫達冶金的產品有:硅碳球、增硅劑、碳化硅、金屬硅粉、硅微粉、包芯線等,我公司產品質量穩定可靠,均可按用戶要求進行品質保證,現貨供應!詳情了解:http://www.centralpennbldgsvs.com
