石墨伸出殼外而畸形長大，形成非球狀石墨。(5)溫度:若鐵液溫度過高，鐵液氧化嚴重，由于鎂與稀土易與氧化物產(chǎn)生還原反應(yīng)，而使得鎂、稀土含量降低，同時高溫也將增加鎂的燒損和蒸發(fā)；鐵液溫度太低，球化劑不能熔化和被鐵液吸收，而上浮至鐵液表面燃燒或被氧化。(6)滯留時間：鐵液中鎂的含量是隨孕育處理后停留時間的增加而減少，其主要原因是因硫及鎂、稀土的氧化與蒸發(fā)造成的。一般情況下，滯留時間不超過20min。(7)澆冒口：澆冒口若設(shè)計不合理，會產(chǎn)生澆注時間太長、鐵液飛濺以及卷入空氣，使鎂、稀土氧化嚴重。(1)嚴格控制鐵液成分：選擇合適的碳當量；鐵液中的含硫量應(yīng)小于008%(其中生鐵含硫不得大于003%，焦碳含硫不得大于008%)，可采用小蘇打進行脫硫。(2)加入足夠的球化劑，一般為～；此外應(yīng)注意球化劑的質(zhì)量，若球化劑破碎后使用，放置時間不得超過一周。處理后的球鐵鐵液中稀土鎂的殘留量不應(yīng)過低，Ｍｇ殘>002%，ＲＥ殘>002%。(3)合理設(shè)計鑄件結(jié)構(gòu),避免壁厚過大，也可在壁厚處加冷鐵以提高凝固速度，縮短液態(tài)時間，從而防止球化衰退及不良。(4)注意處理溫度。出爐溫度應(yīng)低于1460℃，以防球化劑嚴重燒損；要防止高溫下的氧化現(xiàn)象，蓋好覆蓋球化劑的鐵板。米東區(qū)球墨鑄鐵管公司哪家強阿克蘇球墨鑄鐵水篦子標準。</p><div

金屬液表面的熔渣變得太稀薄，不易自液體表面去除，往往隨金屬液流入型內(nèi)。而實際生產(chǎn)中，澆注溫度太低是引起夾渣的主要原因之一。此外，澆注溫度的選取還應(yīng)考慮碳、硅含量的關(guān)系。(5)澆注系統(tǒng):澆注系統(tǒng)設(shè)計應(yīng)合理,具有擋渣功能,使金屬液能平穩(wěn)地充填鑄型,力求避免飛濺及紊流。(6)型砂：若型砂表面粘附有多余的砂子或涂料，它們可與金屬液中的氧化物合成熔渣，導(dǎo)致夾渣產(chǎn)生；砂型的緊實度不均勻，緊實度低的型壁表面容易被金屬液侵蝕和形成低熔點的化合物，導(dǎo)致鑄件產(chǎn)生夾渣。(1)控制鐵液成分：盡量降低鐵液中的含硫量(<006%)，適量加入稀土合金(01%～02%)以凈化鐵液，盡可能降低含硅量和殘鎂量。(2)熔煉工藝：要盡量提高金屬液的出爐溫度，適宜的***，以利于非金屬夾雜物的上浮、聚集。扒干凈鐵液表面的渣子，鐵液表面應(yīng)放覆蓋劑(珍珠巖、草木灰等)，防止鐵液氧化。選擇合適的澆注溫度，比較好不低于1350℃。(3)澆注系統(tǒng)要使鐵液流動平穩(wěn)，應(yīng)設(shè)有集渣包和擋渣裝置(如濾渣網(wǎng)等)，避免直澆道沖砂。(4)鑄型緊實度應(yīng)均勻，強度足夠；合箱時應(yīng)吹凈鑄型中的砂子。3石墨漂浮(1)碳當量：碳當量過高，以致鐵液在高溫時就析出大量石墨。由于石墨的密度比鐵液小。阿勒泰離心球墨鑄鐵管哪家好。米東區(qū)球墨鑄鐵管公司哪家強</p><p

620系列V8、V12、V16柴油機是河南柴油機重工有限公司引進德國MWM公司的大功率柴油機，材質(zhì)為QT500—7，呋喃樹脂砂造型、制芯，澆注重量1400～2800kg，在實現(xiàn)無冒口鑄造之前的工藝如圖1所示。雖然自生產(chǎn)以來工藝不斷改進，但以V12為例，澆注重量1850kg，外型冷鐵需42塊，陶瓷過濾片14片，冒口14個，在側(cè)面φ60mm孔和V型面端頭φ36mm孔等處仍有縮松等鑄造缺點。圖1從620機體的結(jié)構(gòu)來看：要實現(xiàn)無冒口鑄造比較好金屬液從油底殼處引入，620機體總高729mm（從油底殼至缸口比較高處），落差不大，可以實現(xiàn)金屬液從油底殼處引入（即頂注）。頂注工藝有利于金屬液自下而上的凝固，有利于鑄件的補縮，同時也有利于消除鑄件的冷隔。因此考慮將澆注系統(tǒng)移至油底殼處，并在橫澆道與內(nèi)澆道搭接處加大，以取代原發(fā)熱保溫冒口，利用自下而上的凝固順序，去除所有外型冷鐵和發(fā)熱保溫冒口，以減少澆注量，去除10片陶瓷過濾片，僅在橫澆道搭接處保留4片，以過濾金屬液，同時適當調(diào)整化學成分：wC＝～、wSi＝～、wMn＝～，澆注溫度1350～1370℃，澆注時間控制在（45±5）s。通過在三個機型的調(diào)試生產(chǎn)和試加工證明，用無冒口鑄造工藝，生產(chǎn)的機體毛坯基本無鑄造缺點。烏魯木齊縣球墨鑄鐵管電話</p><p
