國外球鐵曲軸的應(yīng)用也十分***，早在上世紀(jì)50年代，國外就開始將球墨鑄鐵應(yīng)用于曲軸的生產(chǎn)，如美國的福特公司首先應(yīng)用，美國克萊斯勒公司、瑞士的GF公司、法國的雷諾和雪鐵龍公司、意大利的菲亞特公司、羅馬尼亞的布拉索夫汽車廠等先后成功地將球墨鑄鐵應(yīng)用于曲軸的生產(chǎn)。在德國，排氣量2000ml以下的柴油機(jī)中球鐵曲軸占50%，排氣量1500ml以下的汽油機(jī)中球鐵曲軸占80%；在美國汽車行業(yè)中，球鐵曲軸占80%。由于制造技術(shù)和經(jīng)濟(jì)上的優(yōu)勢，球鐵曲軸在汽車工業(yè)中***應(yīng)用的總體狀況今后不會發(fā)生太大的變化。2、球鐵曲軸的熔煉對于球鐵的熔煉，國內(nèi)外采用沖天爐，工頻爐雙聯(lián)熔煉的較多。鐵液一般要經(jīng)過脫硫處理，鐵液脫硫方式現(xiàn)在多采用多孔塞脫硫方法，即吹N2氣加入CaC2或復(fù)合脫硫劑攪拌脫硫。脫硫的穩(wěn)定性對于熔煉曲軸鐵液具有重要意義，如采用感應(yīng)電爐熔煉可以更好地控制合金成分范圍，穩(wěn)定球化，易于保證鐵液質(zhì)量。_球化處理是球鐵曲軸生產(chǎn)的重要環(huán)節(jié)，石墨的形態(tài)不僅影響曲軸本體強(qiáng)度性能，而且會影響到曲軸疲勞強(qiáng)度與抗沖擊性能。球化劑的選用對于球化處理結(jié)果具有重要意義。稀土具有較好的脫硫及平衡微量元素有害傾向的作用，凈化鐵液，穩(wěn)定生產(chǎn)。阿克蘇給水球墨鑄鐵管推薦。天山區(qū)球墨鑄鐵管廠家電話</p><p
