电子束冷床熔炼参数对熔池表面温度的影响
Effect of Melting Parameters on Surface Temperature of Melt Pool of TC4 Alloy during Electron Beam Cold Hearth Melting
【摘要】 使用M9100图像高温仪精确测定了TC4合金电子束冷床熔炼时坩埚和冷床熔池表面的温度。结果表明,结果表明,熔炼工艺参数如熔化速度、熔炼功率、电子束扫描方式和扫描频率都会对熔池表面温度产生剧烈影响。
【Abstract】 The surface temperature of melt pool in crucible and hearth of TC4 alloy during electron beam cold hearth melting was measured accurately by using M9100 pyrometer.The results show that the surface temperature of melt pool is affected intensively by melting parameters such as melting rate,melting power,electron beam scanning pattern and scan frequency,etc.
