mathematical model of solidification thermol conduction
gongdingn一nggu ehuanre mox一ng钢锭凝固传热模型(mathematieal model ofsolidifieation thermol eonduetion)描述钢锭凝固过程中温度场变化规律的数学表达式。由钢液转变为钢锭或铸坯、铸件，要放出大量的热，包括钢液的过热显热、结晶潜热和凝固层的降温显热。凝固过程中这些热量的散失方式及其强度，直接影响钢锭的凝固速度、结晶组织、物理和化学不均匀性及表面质量等。钢凝固传热的基本规律及特点首先是钢锭和钢锭模在凝固过程中的温度场既随空间变化，又随时间变化，即属于三维不稳定态传热;其次，它包括钢锭模与钢锭凝固层间的传导传热，钢液内部的传导及对流传热，流动的钢液与凝固前沿的对流及传导传热，以及钢锭与锭模之间气隙中的辐射、传导及对流传热等等，属于综合传热过程。对如此复杂的三维不稳定态综合传热的凝共、刃仅为温度的函数，而与空间位置无关。这样，对于扁锭，三维的不稳定态导热微分方程式便简化为:贵一。10t上大下小镇”钢钢“内温度变化曲线图逃。。。。、、。、。。、、，。**。，*_七。卜品一嘛线都表示钢锭半高处的锭表
