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機體的結構來看：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，同時適當調整化學成分：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試生產和試加工證明，用無冒口鑄造工藝，生產的機體毛坯基本無鑄造缺點。</p><div
