TC4合金的电子束冷床熔炼热平衡计算

通过对TC4合金电子束冷床熔炼过程热平衡的计算和实验验证,为制定合理的熔炼工艺提供了理论依据。结果表明,对于100kg/h的熔炼速度,维持冷床液态熔池表面125℃过热和结晶坩埚内100℃过热的条件下,熔炼原料的功率为70kW,维持冷床内液态熔池的功率为122kW,维持结晶坩埚良好凝固温度的功率为62kW。在此功率熔炼时冷床内液态熔池表面温度和计算吻合。

Heat Balance Calculation of Electron Beam Cold Hearth Melting Process of TC4 Alloy

Instead of the traditional vacuum arc remelting process, electron beam cold hearth melting process as advanced titanium alloy melting technology, is widely used in the titanium melting plant in the world due to its outstanding inclusion removing ability and reducing production cost ability. Through the heat balance calculation of TC4 alloy during the electron beam cold hearth melting process, the research provides the theoretical basis to make the suitable melting recipe. The calculation result shows that, ...
