摘要

采用1:0.8比例水模型和基于Fluent软件的数值模拟

实验研究了190 mm×(1500～1900)mm宽板坯连铸结晶器的流场。结果表明

在钢水流量不变的情况下

随着结晶器断面宽度的增加

流股的冲击深度增加

流股涡心高度降低

结晶器表面流速、液面波动、流股对结晶器窄面的壁面剪切力均减小

卷渣和液面裸露几率逐渐降低。在钢水流量不变的情况下

随着结晶器断面宽度的增加

若采用同一水口

可以适当减小水口插入深度。

Abstract

The flow field in 190 mm x (1 500 ~ 1 900) mm wide slab casting mold has been studied by using a scale l：0

8 water model and numerical simulated by Fluent software. Results show that in constant of liquid flow rate

with increasing the width of mold

the impact depth of flow increases

the level of vortex center drops

the flow rate at liquid surface in mold

the liquid level fluctuation and the shear stress of liquid flow to narrow side of mold decrease

and the probability of slag entrapment and bare liquid surface reduces gradually. In constant of liquid flow rate and using same nozzle

with increasing the width of mold section it is available to properly decrease the submerged depth of submerged nozzle.
