硅鈣包芯線產品介紹

發布:安陽坤鑫達冶金耐材有限公司瀏覽:1030次

硅鈣包芯線是由硅鈣合金加工成粉后由帶鋼包裹后經包芯線機加工而成,其不僅保留了硅鈣全合金原有的脫氧效果又增加了鈣反映的深度從而提高了鈣的收得率,是一種不錯的煉鋼脫氧好產品!

有利于調整和控制易氧化元素和微量元素的含量,能較大幅度提高合金收得率,降低冶煉成本,縮短冶煉時間,準確控制成分。

能起到純潔鋼夜及部分改變夾雜物性質和形態的作用,提高鋼水質量、改善澆鑄狀態。包芯線分內抽式和外放式兩種,喂線所需的機械設備簡單可靠,占地面積少。

芯線包裝質量:包履牢固,不漏粉,不開縫,不折線,無虛包,無空包,粉芯密度均勻,表面光潔無油污。
