During the temperature fields, the results indicate that the processing parameters such as the extrusion velocity, casting temperature, perform preheating temperature, die preheating temperature and so on are important for the temperature fields besides the dwell time. they are must be in concordance each other to the deforming zone is in the quasi - solid state, and the stable semi - solid extrusion is implemented. during the deforming fields, the hyperbolic sine thermo - rigid - viscoplastic fem model is selected according to the forming feature of the process, and the variations of the stress - strain fields are studied
在溫度場的模擬中，模擬結果表明，保壓時間是影響製件成形質量的關鍵因素之一，擠壓速度、液態金屬澆注溫度、預制體預熱溫度和模具預熱溫度等工藝參數對溫度場的影響也很大，需進行參數之間的協調，只有當變形區內部始終維持準固態時，才能實現穩定的液-固擠壓成形過程；在變形場的模擬中，根據液態浸滲擠壓的成形特徵，選用了雙曲正弦剛-粘塑性有限元計算模型，研究了變形過程中應力應變場的變化規律，研究了模角對變形和金屬流動的影響及變形力的變化過程和其影響因素。 -
These critical factors have been given particular attention in the subsequent development and design of this kiln type, while maintaining the unique features of pfr - kiln principles, i. e. the parallel flow of material and combustion gases in the burning zone and the regenerative preheating of combustion air
內部形狀這些關鍵因素已經在這種窯型后來的發展和設計上被特別給予關注，同時保留併流蓄熱的窯型的原理，例如燃燒帶的原料和燃燒氣體的併流和助燃空氣的再預熱。 -
Adopting step - motor drive, upper / lower & back exhausting filter structure ; auto - proportioned flux supply ; special wind way design for good protection of the muzzle and avoiding flux flying to preheating zone, reducing any chance of unsafe troubles
採用步進馬達驅動，上下及后側抽風過濾方式，助焊劑自動供給，特殊風道設計，有效保護噴嘴，防止助焊劑逃逸至預熱區，減少安全隱患。
