鑄造用孕育劑種類有哪些

發布:安陽坤鑫達冶金耐材有限公司瀏覽:1101次

孕育劑的類型有很多的,而且在一些冶金行業中使用的非常廣泛,孕育劑都是用來做鑄鐵的,在機械工業上以及鋼鐵上都有使用,是一種添加劑一種合金劑,起到了很好的凈化作用,可以得到優質的鋼材。

孕育劑從而提高材質的機械性能和使用效果。還原高錳渣 ,熔煉過程中加入提高力學性能,細化晶粒。硅鈣鋇孕育劑主要應用于球墨鑄鐵和灰鑄鐵鉄液的孕育。硅鋯孕育劑和硅鍶孕育劑主要應用于灰鐵鐵液的孕育,其中硅鍶孕育劑對防止鑄件縮松有顯著作用,硅鋇鈣孕育劑強烈增加石墨化核心,細化石墨,促進灰鑄鐵件中得到A型石墨,提高強度,對于球墨鑄鐵件能使球鐵中石墨細小,圓整,提高球化等級??顾ネ四芰?,同時防止相關聯的球化衰退。壁厚敏感性小,組織均勻。顯著減少白口傾向,降低相對硬度,提高鑄件切削加工性能。在鑄鐵工業中用作孕育劑和球化劑。鑄鐵是現代工業中一種重要的金屬材料,它比鋼便宜,容易熔化冶煉,具有優良的鑄造性能和比鋼好得多的搞震能力。

特別是球墨的鑄鐵,機械的性能是可以達到鋼的機械性能的,而且在鑄鐵中如果加入硅鐵那么可以促進石墨化,所以說在球墨鑄鐵中,孕育劑的使用是非常有必要的。
