Example Embodiment
[0018] Example 1: A method for preparing high-purity superalloys by using cast superalloy return material
[0019] The raw material used is 100% K417 alloy return material to prepare 417 master alloy.
[0020] The specific purification smelting steps are:
[0021] Step (1), charging: install the yttrium oxide crucible and the fully preheated ingot mold in the vacuum induction melting furnace, clean the crucible and the ingot mold, and install alumina or yttrium oxide ceramic filter on the sprue cup ; Yttrium oxide crucible and ingot mold cleaning: use a dust collector to clean the yttrium oxide crucible and the inner wall of the ingot mold; first add the pretreated high-temperature alloy return material to the yttrium oxide crucible, and close the vacuum induction melting furnace door;
[0022] In the step (1), the method for pretreatment of the high-temperature alloy return material is to blow or polish the high-temperature alloy return material, and then use industrial ultrasonic cl...
