Abstract

See full text

Disclosed in the present disclosure is a method for smelting a high-temperature alloy with an ultrahigh N content in a VIM furnace, and a high-temperature alloy with an ultrahigh N content. The VIM-furnace smelting method comprises a smelting step performed in a VIM furnace, and a casting step, wherein at a later stage of smelting, a nitrogen-containing substance is added to the VIM furnace to adjust the content of N. In the present disclosure, by comprehensively improving the raw materials, the smelting process, etc., the yield of N during a VIM-furnace smelting process is increased and accurate control over the content of N in the high-temperature alloy is achieved, such that a target content of nitrogen can be guaranteed, and an ideal product can thus be obtained.
