Embodiment approach 1
[0012] First 1. graphite powder, titanium powder and yttrium powder are counted as by mass percent Wt%: Ti 0.50, C1.00, the proportioning requirement of Y 0.10, weigh the raw material and mix and press into prefabricated block for subsequent use;
[0013] II. Preheat the pure aluminum ingot, then put it into a graphite crucible heated to 450°C, and then adjust the temperature to 760°C;
[0014] III. When all the pure aluminum ingots to be loaded are melted, heat up to 830°C, then add spare prefabricated blocks in batches and cover them with cryolite covering agent, keep warm for 25 minutes, remove slag, and then add refining agent C 2 Cl 6 Refining, the amount of refining agent is 1.3% of the total weight of the alloy, while refining, evenly stirring, and then standing for 40 minutes to obtain a clean aluminum, titanium, carbon, yttrium intermediate alloy metal liquid, and then pour it into the preheated Solidification and crystallization in ordinary metal casting molds; then...
Embodiment approach 2
[0018] First 1. graphite powder, titanium powder and yttrium powder are counted as by mass percent Wt%: Ti 6.00, C10.00, the proportioning requirement of Y3.00, it is said that raw material is mixed and pressed into prefabricated block for subsequent use;
[0019] II. Preheat the pure aluminum ingot, then put it into a graphite crucible heated to 450°C, and then adjust the temperature to 760°C;
[0020] III. When all the pure aluminum ingots to be loaded are melted, heat up to 830°C, then add spare prefabricated blocks in batches and cover them with cryolite covering agent, keep warm for 25 minutes, remove slag, and then add refining agent C 2 Cl 6 Refining, the amount of refining agent is 1.3% of the total weight of the alloy, while refining, evenly stirring, and then standing for 40 minutes to obtain a clean aluminum, titanium, carbon, yttrium intermediate alloy metal liquid, and then pour it into the preheated Solidification and crystallization in ordinary metal casting mo...
