球墨鑄鐵、鑄鐵、鑄鋼的區(qū)別？與鑄鐵相比，球墨鑄鐵在強度方面具有的優(yōu)勢。球墨鑄鐵的抗拉強度是60k，而鑄鐵的抗拉強度只有31k。球墨鑄鐵的屈服強度是40k，而鑄鐵并沒有顯示出屈服強度，并且較終出現(xiàn)斷裂。球墨鑄鐵的強度-成本比遠遠優(yōu)于鑄鐵。球墨鑄鐵的強度和鑄鋼的強度是可比的。球墨鑄鐵具有更高的屈服強度，其屈服強度較低為40k，而鑄鋼的屈服強度只有36k。在大部分市政應(yīng)用領(lǐng)域，如：水、鹽水、蒸汽等，球墨鑄鐵的耐腐蝕性和抗氧化性都超過鑄鋼。由于球墨鑄鐵的球狀石墨微觀結(jié)構(gòu)，在減弱振動能力方面，球墨鑄鐵優(yōu)于鑄鋼，因此更加有利于降低應(yīng)力。選擇球墨鑄鐵的一個重要的原因在于球墨鑄鐵比鑄鋼成本低。球墨鑄鐵的低成本使得這種材料更加受歡迎，鑄造效率更高，也較少了球墨鑄鐵的機加工成本。作為鋼的替代品，1949年人類開發(fā)了球墨鑄鐵。鑄鋼含碳量少于，而鑄鐵和球墨鑄鐵含炭量量則至少為3%。鑄鋼中的低含碳量使得作為游離石墨存在的碳不會形成結(jié)構(gòu)薄片。鑄鐵內(nèi)的碳天然形式是游離石墨薄片形式。在球墨鑄鐵內(nèi)，這種石墨薄片通過特殊的處理方法變化成微小的球體。這種改進后的球體使得使得球墨鑄鐵比鑄鐵和鋼相比具有更加優(yōu)異的物理性能。正是這種碳的球狀微觀結(jié)構(gòu)。阿克蘇球墨鑄鐵水篦子生產(chǎn)廠家。新市區(qū)球墨鑄鐵管電話</p><p

縮孔縮松球墨鑄鐵由於其糊狀凝固的特徵決定所生產(chǎn)的鑄鐵由於補縮不良經(jīng)常產(chǎn)生縮孔、縮松等缺點，為了能在鑄件生產(chǎn)以前預(yù)測這些缺點情況，早在印年代國內(nèi)外就開展了鑄造過程數(shù)值類比。鑄造過程數(shù)值類比是使用數(shù)值類比技術(shù)，在計算機虛擬的環(huán)境下類比實際鑄件形成過程，包括金屬液體的充型過程、冷卻凝固過程、應(yīng)力形成過程、判斷成型過程中主要原素的影響程度，預(yù)測組織、性能和可能出現(xiàn)的缺點，為優(yōu)化工藝減少廢品提供依據(jù)。1962年丹麥的Forsund***個采用電子計算機類比鑄件的凝固過程，此后美國、英國、德國、日本、法蘭西等相繼開展了這方面的研究。我國于70年代末開始，大連理工大學(xué)、沈陽鑄造研究所率先在我國開展了這一技術(shù)的研究，并分別于1980年發(fā)表了研究報告(郭可韌等，大型鑄件凝固過程的數(shù)字類比，大連工學(xué)院學(xué)報，1980(2)1─16;沈陽鑄造研究所，鑄件凝固熱場電子計算機類比，鑄造，此后在我國高等院校投入大量人力開展了這項研究。在"六五"、"七五"期間國家攻關(guān)項目中部有計算機在鑄造中應(yīng)用的攻關(guān)項目，"六五"的項目為"大型鑄鋼件凝固控制"、"七五"項目為"大型鑄鋼件鑄造工藝CAD"，組織產(chǎn)、學(xué)、研聯(lián)合攻關(guān)，**推展了此項技術(shù)在我國的發(fā)展。新市區(qū)球墨鑄鐵管電話</p><p
