A Simple Model to Calculate Dendrite Growth Rate during Steel Continuous Casting Process
Abstract
In the current paper, the relationship between the casting speed and the dendrite growth during steel continuous casting process was studied; and a simple mathematical model to calculate the primary dendrite growth rate according to the casting speed was developed. the model was used to predict the distribution of the dendrite growth rate along width direction and casting direction during a continuous casting process, indicating a dendrite growth rate of 0.1-3.0 mm/s, which is much higher than that in regular ingot casting. the dendrite growth rate fluctuates along casting direction because of the different cooling intensity in each zone of the continuous caster; and the distribution of the dendrite growth rate along width direction was non-uniform due to the uneven transverse distribution of cooling intensity. the predicted results agree well with the measurements. © 2010 ISIJ.
