Based on numerical methods, a mathematical model of two-dimensional unsteady heat transfer is developed to simulate the heat transfer of killed ingot, and verified by the experiment measurment in a factory. 通过数值计算方法,建立了镇静钢锭热过程的数学模型,并通过现场的实际测定对其进行了修正。
Design and application of small killed ingot 小型镇静钢锭模的设计与应用
Macrosegregation of killed high carbon steel ingot 高碳镇静钢钢锭的宏观偏析
The temperature field and its change in solidification process of the head zone of killed steel ingot in 610 type mould were measured, and a heat equilibrium diagram has been established. Different effects of three kinds of insulation material on thermal efficiency were determined. 测定了610型镇静钢锭帽口凝固过程的温度场分布及变化,计算并编制了热平衡图,找出三种不同保温材质对钢锭帽口热效率的影响。
This paper has theoretically studied the effect of blowing Ar into molds on improving killed steel ingot quality. 本文从理论上分析了采用锭模吹氩对提高镇静钢质量的作用。
