摘要

用CFD三维计算软件

采用k、ε双方程模型在给定的数值计算条件下

对900 mm高的板坯连铸结晶器内钢液流场进行了数值模拟

研究结晶器工艺参数对结晶器液面湍动能和窄边冲击压力的影响。结果表明:对于断面尺寸为220 mm×900 mm的板坯结晶器

水口插入深度为180 mm

水口倾角为向下15°

拉坯速度为1.6～1.8 m/min时

结晶器内钢液具有较好的流动方式。

Abstract

Fluid field of molten steel in mould with 900 mm height for slab continuous casting has been simulated using k-e double equation model under numerical calculation conditions by a 3 dimensional mathematical software CFD to study effect of process parameters of mould on distribution turbulent kinetic energy at liquid level in mould and impact pressure at narrow side of mould. Results showed that for cross section 220 mm x 900 mm slab mould

the molten steel in mould had better flowage condition as immersion depth of nozzle was 180 mm with exit angle 15° and casting speed 1.6 ~ 1. 8 m/min.
