包(bao)芯線技術(shu)是80年代在噴射(she)冶金技術(shu)基(ji)礎上(shang)發展起來的一種爐外(wai)精(jing)煉手段。包(bao)芯線適用(yong)于煉鋼和鑄造。
用(yong)于煉鋼能(neng)凈(jing)化鋼夾雜(za)物(wu)形態，提(ti)高鋼水可鑄(zhu)性，改善鋼的(de)使用(yong)性能(neng)，并能(neng)提(ti)高合金(jin)的(de)收得率，降低合金(jin)消耗，降低煉鋼成(cheng)本(ben)，經濟效益明顯。
1、有利于調整(zheng)和控制易氧化元(yuan)素和微(wei)量元(yuan)素的(de)(de)含量，能較(jiao)大幅度提高(gao)合金(jin)收得率，降低冶煉(lian)成(cheng)本，縮短冶煉(lian)時間(jian)，精確控制成(cheng)分(fen)(fen)。 2、起(qi)到純潔鋼液(ye)及部(bu)分(fen)(fen)改(gai)變夾雜物性質(zhi)和形態的(de)(de)作(zuo)用，提高(gao)鋼水質(zhi)量、改(gai)善澆(jiao)鑄(zhu)狀態。 3、包(bao)芯(xin)線分(fen)(fen)內抽式和外(wai)放式兩(liang)種，喂線所需(xu)的(de)(de)機械(xie)設備簡單可靠，占地面(mian)積(ji)少(shao)，特別是內抽式包(bao)芯(xin)線更能適應場地窄小的(de)(de)地方使(shi)用。
排線(xian)包(bao)裝:臥式和(he)立式兩(liang)種排線(xian)方式。分內(nei)抽(chou)頭式和(he)外放式兩(liang)種包(bao)裝方式。
