The melting process of vertical tin cladding is experimentally and numerically studied. The influence of heating powers, cladding thicknesses and ambient conditions on the melting process was evaluated and the cylindrical wall stress model was introduced to analyze swelling deformation. Experimental results show the melting process can be divided into three stages: heating, melting and disintegration, and the melting stage can be subdivided into three sub-stages: droplet leaking, swelling deformation and cladding breakage. The stress model suggests swelling deformation and cladding breakage are affected by two mechanisms-metal melting and stress limit, the degree of swelling deformation depends on cladding thicknesses, and there is a negative correlation between the height of the breakage and the product of heating powers and melting time. Numerical results show the melting process can be divided into four stages: heating, melting, breakage and re-solidification, the occurrence of the cladding breakage is a turning point in the melting process, the breakage height is affected by ambient temperatures. The melting stage is guided by two heat transfers-the heat transfer from inside to outside and the heat transfer related to transporting the heat to the lower region by liquid tin flowing downward along the solid tin layer.

对立式锡包层的熔化过程进行了实验和数值研究。评估了加热功率，熔覆层厚度和环境条件对熔化过程的影响，并引入了圆柱壁应力模型来分析溶胀变形。实验结果表明，熔化过程可分为加热，熔化和分解三个阶段，熔化阶段可分为三个子阶段：液滴泄漏，溶胀变形和包壳破裂。应力模型表明溶胀变形和包壳破裂受两种机制的影响-金属熔化和应力极限，溶胀变形的程度取决于包壳厚度，并且破裂高度与加热功率乘积之间呈负相关。融化时间。数值结果表明，熔化过程可分为加热，熔化，破裂和再凝固四个阶段，包层破裂的发生是熔化过程的转折点，破裂高度受环境温度的影响。熔化阶段受两个热传递的引导-从内部到外部的热传递，以及与通过沿着固态锡层向下流动的液态锡将热传递到下部区域相关的热传递。
