摘要

建立了双辊式薄带钢铸轧过程的三维流场与温度场耦合数学模型

研究了工艺参数对铸轧过程的影响。结果表明 :较低的过热度可以在薄带的整个厚度方向上得到较为均匀的组织

但是过热度太低则易使金属冷凝在浇注系统中

不利于夹杂物上浮 ;铸轧速度在v≤vc的一定范围内可使凝固终点正好在辊缝吻合点以上 2～ 8mm范围内。通过该模型的研究

可为控制带钢铸轧过程打下理论基础。

Abstract

A 3-D mathematical model for flowing field coupled with temperature field in strip twin rolling-casting process is developed

and the effects of processing parameters on roll-casting process were studied. The results showed that relevant homogeneous structure in thickness direction of the strip can be obtained with lower superheat while the metal was solidified in gating system to obstruct inclusion removal with too low superheat. Solidified end-point can be just located at the range of 2～8 mm above the anastomosing point of roll gap when rolling-casting velocity is at a certain ranges of v ≤ v c.The proposed model can lay down a theoretical foundation for controlling strip rolling-casting process.
