  1. The quality of furan sand castings is usually better than clay sand castings, however, some defects are also very easy take place with furan sand castings such as blow hole, metal penetration, veining, cracking, slag inclusion, hardness too low, surface recarburation, surface sulphuration, nodularity degeneration etc, which were usually caused by improper raw materials selection, improper method design, incorrect moulding or / and core - making

    摘要呋喃樹脂砂鑄件質量一般比黏土砂鑄件好，但如果原材料選擇、工藝設計、造型和制芯操作不當，也會產生氣孔、粘砂、脈紋、裂紋，夾渣、硬度不足、滲碳、滲硫和球化不良等鑄造缺陷。
  2. Considering the influence of material original flaw, the thesis gave the 4 # 125t crane of no. 3 steel - making plant of maansan steel co. for example to analyze the designing and remaining life of the crane ' s girder by using damnification limits design method. the method was based on the theory of rupture dynamics and the principle of disrepair - security

    本文以馬鋼第三煉鋼廠4 # 125t鑄造起重機主梁下蓋板大面積可見裂紋情況為例，考慮材料初始裂紋的影響，在斷裂力學理論和破損?安全設計原則的基礎上，採用損傷容限設計法來重新計算鑄造起重機的設計壽命；並對正在服役的鑄造起重機計算其剩餘壽命，為鑄造起重機的安全運行提供了較可靠的理論依據。
  3. The fem model was accurate and effective by using submodel and error estimation technique that ensured the reliability of calculation and analysis. the thesis got the measure of critical flaw and designing life of the girder. in addition, the thesis calculated the remaining life of the girder while the flaw reaching 150mm

    結合有限元分析結果和損傷容限設計方法，本文計算了馬鋼第三煉鋼廠4 # 125t鑄造起重機主梁下蓋板的臨界裂紋尺寸，及初始裂紋為0 . 5mm時主梁的設計壽命，並估算了在裂紋尺寸達到150mm時主梁的剩餘壽命。
  4. Abstract : based on the hypotheses of three - piece straightening curve. it isverified that the method for using little deformation condition was true with accurate solution of three - piece straightening curve. the mechanics behavior of slab was analyzed in regard to the creep properties of high temperature slab. the results show that the strain, the strain velocity and the stress varied so smoothly that the inner crack was prevented. technical renovation is carried on by adjusting the displacement of rolls and by using the accurate solution of three - piece straightening curve

    文摘:基於三段矯直曲線應變速率的假設，通過計算三段矯直曲線的精確解，驗證了使用小變形條件的正確性;考慮高溫鑄坯蠕變性能，對鑄坯的力學行為進行了分析，得出了使用三段矯直曲線方法，鑄坯應變速率、應力及應變在矯直區內變化較為平緩，可有效避免鑄坯內裂紋的形成;使用本文三段矯直曲線精確解，調整輥列位置，可進行連鑄機的在線技術改造。
