要得到高与壁厚比 H/T>5的大型板状致密铸钢件是个繁难的任务。铸件的定向凝固系数 K_定等于铸件底部传出的热量与从侧面方向传出的热量的比值,一般可以用下列等式来表示:
It is a daunting task to obtain large, plate-shaped, dense steel castings with a high H / T ratio of 5 to the wall thickness. Casting directional solidification coefficient K_setting equal to the ratio of the heat output from the bottom of the casting and the heat from the side direction can generally be expressed by the following equation:
