球化反應(yīng)控制的關(guān)鍵是鎂的吸收率，溫度高，反應(yīng)激烈，時(shí)間短，鎂燒損多，球化效果差；溫度低，反應(yīng)平穩(wěn)，時(shí)間長(zhǎng)，鎂吸收率高，球化效果好。因此，一般在保證足夠澆注溫度的前提下，宜盡可能降低球化處理溫度，控制在1420～1450℃。球化劑要砸成小塊，粒度一般在5～25mm，加在包底，再在上面加硅鐵和鐵屑。孕育處理是球墨鑄鐵生產(chǎn)過(guò)程中的一個(gè)重要環(huán)節(jié)，它不*促進(jìn)石墨化，防止自由滲碳體和白口出現(xiàn)，而且有助于球化，并使石墨變得更細(xì)小，更圓整，分布均勻，從而提高球墨鑄鐵的力學(xué)性能。孕育劑一般多采用FeSi75，其加入量根據(jù)對(duì)鑄件的力學(xué)性能要求，一般為％～％。孕育劑的粒度根據(jù)鐵液量多少，一般砸成5～25mm的小塊。孕育劑應(yīng)保持干凈、干燥。球化劑和孕育劑要在出鐵前加入包中，在連續(xù)生產(chǎn)時(shí)，剛出完前一爐鐵后，包很熱，過(guò)早加入會(huì)使其粘結(jié)在包底而削弱球化和孕育效果。為了延遲球化反應(yīng)時(shí)間，增強(qiáng)球化和孕育效果，要在球化劑和孕育劑的上面覆蓋一層鐵屑。球化處理的方法較多，一般多采用操作簡(jiǎn)便的沖入法處理球鐵。球化效果爐前檢驗(yàn)爐前檢驗(yàn)孕育、球化效果好壞，一般采用三角試樣。澆注三角試樣，冷至暗紅色，淬水冷卻，砸斷后觀察斷口。斷口銀白色，前列白口。阿克蘇球墨鑄鐵搶修節(jié)銷(xiāo)售廠家。</p><div
