摘要
介绍了铸铜冷却壁的热态实验结果,采用数值模拟的方法分析了炉温、边缘接触压力对铸铜冷却壁热应力和热变形的影响.热态实验结果表明,铸铜冷却壁的冷却能力与轧制铜冷却壁相当,能够承受180 kW/m2的热负荷,短时间内能承受250 kW/m2的热负荷.热应力计算结果表明:铸铜冷却壁在高热负荷下不会产生疲劳裂纹.通过在杭钢2号高炉的工业测试说明铸铜冷却壁有很强的挂渣能力,且渣皮稳定.因此,铸铜冷却壁满足了高炉长寿的要求.由于铸铜冷却壁具有冷却能力大、自由布置冷却通道走向、成本较低等优势,因此有着很好的工业应用前景.
The cast copper stave was first systemically studied,including hot test and Hangzhou Steel＇s No.2 BF industry test results.Using a numerical simulation method,the effect of furnace temperature,edge contact pressure on thermal stress and thermal deformation of the cast copper staves was researched.The hot test results indicate the maximum heat flux of the cast copper stave is 180 kW/m2,even in a short time,it can reach 250 kW/m2.Its cooling capacity is equivalent with rolled copper staves.The calculation results of heat stress indicate that the cast copper staves will not generate fatigue crack under high heat loading.The industry test results show the cast copper staves maintain a more stable accretion layer.Because the advantage with higher cooling capacity,special pathway orientation of cooling channel and low cost for the cast copper staves,it has an extensive application for future.
