金屬硅判斷優良標準!

發布:安陽坤鑫達冶金耐材有限公司瀏覽:652次


  金屬硅被應用的越來越多,相對而來的是市場上的金屬硅紛涌而來,五花八門,面對這么多的金屬硅,我們怎樣才能挑選到優良的金屬硅呢?不僅是消費者,作為金屬硅廠家,只有保障了金屬硅的質量,企業才能長久發展。那么如何評判金屬硅質量問題呢?安陽坤鑫達冶金耐材有限公司給大家解答一下。

金屬硅,金屬硅價格,金屬硅粉廠家

  1、金屬硅中的硫分:硫是生鐵冶煉的雜質之一,它使生鐵質量降低。在煉鋼生鐵中硫含量大于0.07%即為廢品。由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,所以金屬硅是爐料中硫的主要來源。金屬硅硫分的高低直接影響到高爐煉鐵生產。當金屬硅硫分大于1.6%,硫份每增加0.1%,金屬硅使用量增加1.8%,石灰石加入量增加3.7%,礦石加入量增加0.3%高爐產量降低1.5-2.0%。冶金焦的含硫量規定不大于1%,大中型高爐使用的冶金焦含硫量小于0.4-0.7%。

  2、金屬硅中的磷分:煉鐵用的冶金焦含磷量應在0.02-0.03%以下。

  3、金屬硅中的灰分:金屬硅的灰分對高爐冶煉的影響是十分顯著的。金屬硅灰分增加1%,金屬硅用量增加2-2.5%因此,金屬硅灰分的降低是十分必要的。

  4、金屬硅中的揮發分:根據金屬硅的揮發分含量可判斷金屬硅成熟度。如揮發分大于1.5%,則表示生焦;揮發分小于0.5-0.7%,則表示過火,一般成熟的冶金焦揮發分為1%左右。

  5、金屬硅中的水分:水分波動會使金屬硅計量不準,從而引起爐況波動。此外,金屬硅水分提高會使M40偏高,M10偏低,給轉鼓指標帶來誤差。

  6、金屬硅的篩分組成:在高爐冶煉中金屬硅的粒度也是很重要的。中國過去對金屬硅粒度要求為:對大焦爐(1300-2000平方米)金屬硅粒度大于40毫米;中、小高金屬硅粒度大于25毫米。金屬硅粒度在40-25毫米為好。大于80毫米的金屬硅要整粒,使其粒度范圍變化不大。這樣金屬硅塊度均一,空隙大,阻力小,爐況運行良好。
