Formation of freshwater lens in islands and evolution rules of the upconing
海岛淡水透镜体形成及倒锥演变规律分析
Using self-study model to simulate freshwater lens evolution at laboratory,it s formation process in the condition of rainfall has been simulated,the process of upconing movement has also been simulated without any recharge.
模拟了降雨补给条件下淡水透镜体的形成过程;在无补给条件下,开采淡水时倒锥的变化过程。
Relying on its excellent strength and stiffness,circular-shaped cover with a topsy-turvy cone is especially suitable for the end sealing of detachable spiral heat exchanger.
倒锥平盖凭借其良好的强度、刚度特性,尤其适于可拆式螺旋板换热器的端部密封。
The results show that the main reasons are small back draught of the crystallizer,large level fluctuation,high degree of superheat of the tundish and the poor quality of the cooling water for the crystallizer.
由于方坯角部纵裂漏钢事故频繁,通过分析漏钢的特点和机理,认为造成小方坯角部纵裂漏钢的主要原因是结晶器倒锥度小、结晶器液面波动及中间包过热度大、结晶器冷却水质差。
In order to improve the using life of the mould, through constantly exploring in the production practice, the optimal back draught is determined, the mould structures such as water canal distributing, the water ring nozzles and so on are reconstructed, adopting low degree of superheat in pouring and using appropriate protecting slag, and then the mould life is increased from 316 to 774 heats.
为了提高结晶器的使用寿命 ,通过生产实践中的不断探索 ,确定了最佳的倒锥度 ,并对水缝分布、水环喷嘴等结晶器结构进行改造 ,采用低过热度浇铸 ,使用合适的保护渣 ,结晶器使用寿命由原来的年平均 3 16炉提高到 774炉。
