發動機殼體為一個其一端為密封的鋼鑄圓柱缸體，另一端則為敞口的喉道及噴管。In this paper, it is proposed as a new mechanism that when a solidifying billet is in the stirring zone during continuous casting of steel, a thin steel shell is formed in front of the freezing interface, which results in a white band with a negative segregation followed by a positive one
作者提出了一個新的機制來解釋白亮帶的形成原因，即正在凝固的連鑄鋼坯位於攪拌區時，在凝固前沿形成一個薄殼，由此導致先發生負偏析，緊隨其後又發生正偏析的白亮帶。According to numerical simulation and molten steel solidification mechanism, in the paper, the restrict relationship had been setup between casting speed and molten steel level and average mould tapping section thickness as well as its shell temperature at tapping spout
本文基於數值模擬和鋼液凝固機理，建立起結晶器內鋼液液位和鑄坯拉速對其出鋼口處鋼液截面平均溫度和坯殼溫度的制約關系。Testing results are analyzed, then the boundary condition ( the heat transfer coefficient of and the water density ) for computer simulation is acquired. through simulation in computer using the all - purpose computer simulation software secondary cooling in slab continuous casting and test results, the influence of the factor such as casting speed, casting temperature, shell thickness and secondary cooling system are analyzed. the secondary cooling system is evaluated, the reasons of crack are analyzed
應用模擬軟體和實驗數據對寶鋼1930鑄機進行了模擬計算，分析了拉速、配水制度、過熱度對鑄坯溫度場和坯殼厚度的影響；對寶鋼1930鑄機的二冷制度進行了評估，分析了產生裂紋的原因；並對二冷制度進行優化，提出了改進建議。Abstract : according to the site condition of the bisc, a mathematical model of two - dimensional unsteady solidification and heat transfer was established for the bloom caster in the mold. the mathematical model was solved with a finite difference method to characterize the temperature profiles and thickness of the solidified shell in the mold, the effects of casting speed on thickness of the solidified shell are also studied
文摘:根據包鋼的現場條件，建立了大方坯連鑄機結晶器內二維非穩態凝固傳熱數學模型，採用有限差分法對數學模型求解，得出結晶器中鑄坯的溫度分佈規律和凝固坯殼生成規律，同時研究了拉坯速度對坯殼生成厚度的影響分享友人
