摘要

以济钢第一炼钢厂4#板坯连铸中间包为原型

应用湍流流动数学模型对不同堰坝设计方案进行计算机数值模拟

优化中间包的堰坝设计。结果表明

对上口面积3500 mm × 800 mm、底部面积3200 mm × 650 mm的中间包

包内钢水深度为800 mm时

当挡堰高550 mm

挡坝高350 mm

挡堰与水口入口处距离800mm

挡堰与挡坝相对距离400 mm时

钢液具有较好的流动方式

有利于夹杂物上浮。

Abstract

Taking tundish for No4 Slab concaster at Nol steel plant

Jinan Steel

computer numerical simulation for difierent weir and dam design scheme was carried out to optimize design of weir and dam in tundish by using turbulent flowage math model. Results showed that for tundish with top dimensions 3500 mm x 800 mm

bottom dimensions 3200 mm x 650 mm and molten steel depth in tundish 800 mm

molten steel had better flowage condition as weir height 550 mm

dam hei^it 350 mm

distance between weir and nozzle entrance 800 mm and relative distance between weir and dam 400 mm

it was available inclusions floating off.
