在中频感应电炉坩埚打制过程中,有时会因操作问题,使得坩埚出现“打偏”或“打高”现象(打偏、打高指打制的坩埚偏离或高出原先放置的位置)。为防止出现这种情况,除了坩埚放置时位置准确,压铁重量合理、打炉时各处捣打用力均匀之外,还应注意在坩埚打制初期,经常观察并及时调整坩埚的位置。本文介绍一个小窍门供同行参考。 In the process of making the medium frequency induction crucible, the crucible may sometimes be “hit” or “hit high” due to the operation problem (the crucible deviates from or hits the crumpled position higher than the original place). In order to prevent this situation, in addition to the location of the crucible placed accurately, the weight of the weight is reasonable, stampered when the furnace hit hard uniform, but also pay attention to the crucible in the initial production, often observe and adjust the crucible position. This article describes a little trick for peer reference.
