在鎂蒸汽的帶動(dòng)下，使石墨漂浮到鑄件上部。碳當(dāng)量越高，石墨漂浮現(xiàn)象越嚴(yán)重。應(yīng)當(dāng)指出，碳當(dāng)量太高是產(chǎn)生石墨漂浮的主要原因，但不是***原因，鑄件大小、壁厚也是影響石墨漂浮的重要因素。(2)硅：在碳當(dāng)量不變的條件下，適當(dāng)降低含硅量，有助于降低產(chǎn)生石墨漂浮的傾向。(3)稀土：稀土含量過(guò)少時(shí)，碳在鐵液中的溶解度會(huì)降低，鐵液將析出大量石墨，加重石墨漂浮。(4)球化溫度與孕育溫度：為了提高鎂及稀土元素的吸收率，國(guó)內(nèi)試驗(yàn)研究表明，球化處理時(shí)**適當(dāng)?shù)蔫F液溫度是1380～1450℃。在此溫度區(qū)間，隨著溫度升高，鎂和稀土的吸收率增加。(5)澆注溫度：一般情況下,澆注溫度越高，出現(xiàn)石墨漂浮的傾向越大，這是因?yàn)殍T件長(zhǎng)時(shí)間處于液態(tài)有利于石墨的析出。Ｗ.Ｗ.Ｃhaput研究發(fā)現(xiàn),若縮短凝固時(shí)間，隨著澆注溫度升高，石墨漂浮傾向降低。(6)滯留時(shí)間：孕育處理后至澆注完畢之間的停留時(shí)間太長(zhǎng)，為石墨的析出提供了條件，一般這段時(shí)間應(yīng)控制在10ｍｉｎ以內(nèi)。32防止措施(1)控制鐵液成分：嚴(yán)格控制碳當(dāng)量，不得大于46%；鐵液的含碳量不得大于40%，可用廢鋼來(lái)調(diào)整鐵液的含碳量；采用低硅(<12%)生鐵；改進(jìn)孕育處理，增強(qiáng)孕育效果，這樣可降低孕育硅鐵量。。米東區(qū)球墨鑄鐵管哪家性價(jià)比高阿勒泰專業(yè)球墨鑄鐵管廠家直供。</p><div

一、爐前檢驗(yàn)球鑄鐵爐前檢驗(yàn)是其生產(chǎn)過(guò)程中不可缺少的一環(huán)，它直接關(guān)系到球墨鑄鐵件的質(zhì)量。及時(shí)、準(zhǔn)確判斷鐵液的球化情況，可以迅速采取措施控制球墨鑄鐵質(zhì)量。爐前誤判將會(huì)造成大量鑄件報(bào)廢，浪費(fèi)造型工時(shí)，因此爐前的及時(shí)、準(zhǔn)確判斷球化情況比爐后檢驗(yàn)重要得多。實(shí)際生產(chǎn)中常用的爐前檢驗(yàn)鐵液球化情況的方法有以下幾種。1表面結(jié)皮及火苗判斷法稀土鎂球墨鑄鐵含鎂量較低，又有稀土元素，鐵液表面和純鎂球墨鑄鐵不一樣，表面沒有那么多氧化皮，火苗也沒有那么多而有力。但是當(dāng)補(bǔ)加1/3鐵液時(shí)液面會(huì)逸出鎂光及白**火苗，形如燭火。根據(jù)火苗數(shù)量、高度判斷球化情況及鎂殘余量，火苗越高、越有力，說(shuō)明球化良好。尤其是在澆注時(shí)，從鐵液流中可以看到**火，如高度達(dá)25~ffice:smarttags'/>50mm，即球化良好；若火苗低于15mm，則球化較差。從處理后的球墨鑄鐵鐵液表面看，形成氧化膜，并有銀白色滾動(dòng)的亮點(diǎn)，即為球化良好。但氧化膜太厚，則表示鐵液溫度低。2三角試塊法目前，通過(guò)觀察試塊來(lái)判斷球化情況是普遍采用的一種方法。各廠所用試塊形狀很多、尺寸各異，多數(shù)工廠采用三角形試塊。根據(jù)我廠生產(chǎn)特點(diǎn)、鑄件大小和厚薄，選用三角試塊截面積尺寸為（底）×50mm((高）。</p><p
