非真空感应炉熔炼镍基合金的方法

Abstract

The invention discloses a method for smelting a nickel-based alloy by adopting a non-vacuum induction furnace. The method for smelting the nickel-based alloy by adopting the non-vacuum induction furnace comprises the following steps: firstly transforming a medium-frequency induction furnace, then putting materials to be molten into a crucible to be molten, wherein frequency of the medium-frequency induction furnace is controlled to be 1868 minus or plus 5 HZ; continuously injecting inert liquid into the medium-frequency induction furnace in a material smelting process and carrying out deoxidization on molten metal, after the materials are completely molten, carrying out deoxidization for 10-15 minutes, wherein temperature of the molten metal to be 1530 minus or plus 5 DEG C; increasing temperature of the medium-frequency induction furnace to be 1550 minus or plus 5 DEG C after deoxidization is completed, then adding a solid non solution treatment agent into the molten metal, wherein mass ratio of the non solution treatment agent to the molten metal is (2:1000)-(3:1000), and pouring after the non solution treatment agent is completely molten in the molten metal, so that the nickel-based alloy is obtained. The method for smelting the nickel-based alloy by adopting the non-vacuum induction furnace has the advantages that oxidation and inspiration phenomena can be effectively reduced under non-vacuum high temperature condition, and a hump phenomenon can be effectively eliminated.
本发明公开了一种非真空感应炉熔炼镍基合金的方法,首先改造中频感应炉,然后将待熔炼的物料投入坩埚中进行熔化,中频感应炉的频率控制在1868±5HZ范围内;在物料熔化过程中向炉子内连续注入惰性液体对熔融金属熔液进行脱氧处理,物料完全熔化后进行脱氧处理10~15min,熔化后熔融金属熔液的温度控制在1530±5℃范围内;脱氧处理完毕后使炉子温度上升至1550±5℃,然后往熔融金属熔液中添加固体状的免固剂,免固剂与熔融金属熔液的质量比为2:1000~3:1000,当免固剂完全熔化于熔融金属熔液后进行浇注,得到镍基合金件。本发明的优点是:在非真空高温条件下能有效降低出现氧化和吸气现象、并能有效消除驼峰现象。
