620系列V8、V12、V16柴油機(jī)是河南柴油機(jī)重工有限公司引進(jìn)德國(guó)MWM公司的大功率柴油機(jī)，材質(zhì)為QT500—7，呋喃樹脂砂造型、制芯，澆注重量1400～2800kg，在實(shí)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(jìn)，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(gè)，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(diǎn)。圖1從620機(jī)體的結(jié)構(gòu)來看：要實(shí)現(xiàn)無冒口鑄造比較好金屬液從油底殼處引入，620機(jī)體總高729mm（從油底殼至缸口比較高處），落差不大，可以實(shí)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(bǔ)縮，同時(shí)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，*在橫澆道搭接處保留4片，以過濾金屬液，同時(shí)適當(dāng)調(diào)整化學(xué)成分：wC＝～、wSi＝～、wMn＝～，澆注溫度1350～1370℃，澆注時(shí)間控制在（45±5）s。通過在三個(gè)機(jī)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(jī)體毛坯基本無鑄造缺點(diǎn)。新市區(qū)球墨鑄鐵管公司電話阿勒泰離心球墨鑄鐵管廠家直供。</p><div
