一、前言曲軸是汽車發(fā)動機的關鍵部件之一，其性能好壞直接影響汽車的壽命。曲軸工作時承受著大負荷和不斷變化的彎矩及扭矩作用，常見的失效形式為彎曲疲勞斷裂及軸頸磨損，因此要求曲軸材質具有較高的剛性和疲勞強度以及良好的耐磨性能。隨著球墨鑄鐵技術的發(fā)展，其性能也在不斷提高，質量廉價的球鐵已成為制造曲軸的重要材料之一。自1947年球墨鑄鐵發(fā)明以來，經過不長時間的努力，其抗拉強度提高到了600~900MPa，接近或超過了碳素鋼的水平。與鍛鋼材料比較，球墨鑄鐵曲軸既有制造簡便、成本低廉，又有吸震、耐磨、對表面裂紋不敏感等鍛鋼材料所不具備的優(yōu)良特性，因而球墨鑄鐵具備了代替鍛鋼制造曲軸的可能性。20世紀50年代后期，國內南京汽車制造廠率先批量生產躍進牌汽車球鐵曲軸。60年代，二汽首先成為國內按照球鐵曲軸生產工藝進行設計和投產的汽車廠。到了70、80年代，中小型柴油機在我國迅速發(fā)展，由于球鐵制造和經濟方面的優(yōu)勢，大多數中小型柴油機都采用球鐵曲軸，極大地推動了我國球鐵曲軸的應用與發(fā)展，出現了一批球鐵曲軸專業(yè)生產廠。近十多年在汽車工業(yè)的快速發(fā)展過程中，又新建了一批現代化的球鐵曲軸生產廠（或分廠、車間），球鐵曲軸在國內得到了普遍應用。烏魯木齊球墨鑄鐵管銷售廠家阿克蘇離心球墨鑄鐵管廠家直供。</p><div

冷卻至暗紅色，淬火擊斷后，如發(fā)現試塊上表面有一道黑邊，則表示球化不良，且黑邊越厚，球化越差，產生衰退，此時如鐵液溫度高可補加合金。從試塊上還可看出：如試塊周圍成圓弧狀，并中間凹陷，有的還有一道道皺紋，則也表示球化良好；如試塊上表面有麥皮狀的點，則表示鐵液氧化，易于衰退。在這種情況下，應對爐子進行改造。5觀察鐵液凝固狀況球化處理完畢后，取出少量鐵液，澆入Ф30mm圓柱形金屬型內，觀察凝固期間鐵液由表面涌出現象，并根據涌出鐵液數量來判斷鐵液球化情況。球化良好的鐵液，固期間表現出很大的石墨膨脹力，鐵液表面在凝固開始時有些下降，表面結殼后即有少量鐵液由表殼涌出；而球化不良的鐵液表面涌出數量較少。6爐前快速金相觀察上述各種方法皆是利用球墨鑄鐵某一特性間接判斷球化情況，但生產上各種條件變化甚大，所述方法都具有局限性，而爐前快速金相觀察可較多地避免許多因素的干擾，直接觀察球化情況。二、爐后金相檢驗（1）后金相檢驗主要觀察顯微組織如石墨形態(tài)及分特征金屬基體組織夾雜物等通過金相分析可斷件量為一改鑄質提實基。（2）稀土鎂球墨鑄鐵的化學成分分析也可以說是一種檢測手段，如發(fā)現問題，配料人員可作適當調整。阿克蘇球墨鑄鐵水篦子推薦。烏魯木齊球墨鑄鐵管直銷</p><p
