淺談硅鋇鈣

      硅鋇鈣是煉鋼中很好的新型脫氧劑,并且有很好的脫硫、磷能力,對冶煉含硫、磷較低的鋼種起著非常重要的作用,在特鋼系統有著廣闊的應用前景。廣通金屬硅業,專注冶金耐材生產,今天小編帶您進一步了解硅鋇鈣!

 1、定義:

 碳化鈣35-45%、二氧化硅40-45%、硫酸鋇10-30%

 2、主要牌號和化學成份:

 3、性能與用途:

 (1)硅鋇鈣合金是鋇系合金中***新型復合合金,是煉鋼的脫氧劑、脫硫劑、還兼有脫硫的作用;是鑄造中的孕育劑和變質劑。

 (2)鋇在煉鋼溫度范圍內有效地降低鈣的蒸氣壓,增加鈣在鋼液中的溶解度。同硅鈣合金相比,用硅鋇鈣合金作為鈣源加入鋼液中,加入的鈣量即使是硅鈣合金加入量的一半時,鋼液中的鈣含量卻是硅鈣合金的兩倍左右,鈣在鋼液中也顯著提高。充分顯示鋇在鋼液中有效地保護了鈣,降低了鈣的氧化,從而達到了對鋼液鈣處理的目的。
