摘要: 针对首钢160 mm×160 mm方坯连铸机14.5 t中间包建立数学模型,采用流体力学计算软件Fluent对4流异型中间包内钢液流动和温度进行了数值计算,得出中间包钢液流动的速度场、温度场和停留时间分布曲线。计算结果表明,各流最大温度差为8 K,应避免低过热度浇铸;1流死区体积分率为20%略大于其余各流(10%~20%)外,中间包钢水流动参数可以满足生产的需要。

Abstract: A mathematical model for 14. 5 t tundish casting 160 mm x 160 mm billet at Shougang is established and the numerical calculation of flow and temperature of liquid in shape tundish for 4-strand is calculated by using fluid dynamic software Fluent to get the flow speed field, temperature field and residence time distribution curves of liquid in tundish. Calculation results show that the maximum temperature difference between each strand is 8 K, therefore the lower overheating extent liquid shall be avoided; besides the percentage of dead volume of No l strand is 20% little larger than that other strands ( 10% 〜12% ) , the flow parameters of liquid in tundish meet the requirement for casting operation.
