一、爐前檢驗球鑄鐵爐前檢驗是其生產(chǎn)過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、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。爐前誤判將會造成大量鑄件報廢，浪費造型工時，因此爐前的及時、準(zhǔn)確判斷球化情況比爐后檢驗重要得多。實際生產(chǎn)中常用的爐前檢驗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)補加1/3鐵液時液面會逸出鎂光及白**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，說明球化良好。尤其是在澆注時，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，并有銀白色滾動的亮點，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，通過觀察試塊來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、鑄件大小和厚薄，選用三角試塊截面積尺寸為（底）×50mm((高）。</p><p

一般石墨的大小為6-7級，質(zhì)量上要求鑄管的球化等級控制為1-3級(球化率≥80%)，因而材料本身的機械性能得到了較好的改善，具有鐵的本質(zhì)，鋼的性能。退火后的球墨鑄鐵管，其金相組織為鐵素體加少量珠光體，機械性能較好。球墨鑄鐵管主要稱之為離心球墨鑄鐵管，它具有鐵的本質(zhì)、鋼的性能，防腐性能優(yōu)異、延展性能好，密封效果好，安裝簡易、主要用于市政、工礦企業(yè)給水、輸氣,輸油等。是供水管材的優(yōu)先，具有很高的性價比。與PE管材相比，從安裝時間上，球墨管比PE管安裝更簡單快捷，且安裝后內(nèi)外承壓力更好;從密閉性和防腐性上來看，球墨管安裝后的密閉性更好，也可以通過多種防腐手段提高防腐蝕性能;從水力性能來看，因球墨管規(guī)格一般指內(nèi)徑，PE管規(guī)格一般指外徑，因為同等規(guī)格條件下，球墨管能實現(xiàn)更大的徑流量;從綜合安裝維護(hù)造價來看，球墨管有著更加優(yōu)越的性價比。內(nèi)壁噴鋅，水泥沙漿防腐材料等。折疊編輯本段防腐處理1、瀝青漆涂層瀝青漆涂層是用于輸送燃?xì)獾墓艿?。噴漆前對管子進(jìn)行預(yù)熱可以提高瀝青漆的附著力，加速干燥。2、水泥砂漿內(nèi)襯+特殊涂層這種內(nèi)防腐措施適用于輸送污水的管道，可以提高內(nèi)襯的抗腐蝕能力。3、環(huán)氧煤瀝青涂層環(huán)氧煤瀝青涂層既適用于燃?xì)夤艿馈?阿勒泰專業(yè)球墨鑄鐵管銷售廠家。天山區(qū)球墨鑄鐵管銷售廠家</p><p
