Degasser made from above-described embodiment 1~7 and comparative example 1~7 is added to according to the weight ratio of weight 0.1%
It is de-gassed test in the alloy melting liquid of monel refining stage, test result is detailed in shown in the following table 1.
Table 1
| Test example | Oxygen and nitrogen content (ppm) in alloy |
| Embodiment 1 | < 5ppm |
| Embodiment 2 | < 4ppm |
| Embodiment 3 | < 5ppm |
| Embodiment 4 | < 5ppm |
| Embodiment 5 | < 6ppm |
| Embodiment 6 | < 5ppm |
| Embodiment 7 | < 6ppm |
| Comparative example 1 | < 10ppm |
| Comparative example 2 | < 9ppm |
| Comparative example 3 | < 10ppm |
| Comparative example 4 | < 9ppm |
| Comparative example 5 | < 8ppm |
| Comparative example 6 | < 7ppm |
| Comparative example 7 | < 5ppm |
From the test result of upper table 1, it can be concluded that, the degasser that the embodiment of the present invention 1~7 provides is according to weight 0.1%
Weight ratio is added in the alloy melting liquid of monel refining stage, and the oxygen in alloy melting liquid and nitrogen that may make contain
Amount is lower than 6ppm, reduces the number of vacuum melting, reduces the production cost of alloy.
From the Comparability test result of comparative example 1,4 and embodiment 2, it can be concluded that, degasser can be made by adding magnesium and cerium
Degassing performance is more preferably.Magnesium and cerium have synergistic effect, can increase the degasifying effect of degasser jointly.
It can be concluded that, the gold with air contact oxidation is readily able to from the Comparability test result of comparative example 3 and embodiment 2
Belong to magnesium and cerium and be placed on melting in power frequency induction furnace and be more advantageous to and protects magnesium and cerium that oxidization burning loss does not occur in fusion process, and
And the degassing performance of degasser is good.
From the comparison result of comparative example 5 and embodiment 2, it can be concluded that, addition Nacl, which is more advantageous to, builds isolation air
Melting environment protects melting liquid by the oxidization burning loss of air, not ensure that the degassing performance of degasser.
It is unfavorable for building from the thickness that can be seen that Nacl in the comparison result of comparative example 6~7 and embodiment 2 is too thin
Completely cut off the melting environment of air, magnesium and cerium will appear the oxidization burning loss of part in fusion process, and it is too thick if be then easy to make
At the waste of Nacl.
Magnesium elements are a kind of highly active elements, are easily oxidized to magnesia in air, according to phasor, 760 DEG C compared with
Under low smelting temperature, for solubility of the magnesium in nickel and copper substantially 30% or so, the content of magnesium higher than 30% can make melting
Temperature increases, since the alloy is melting in air, temperature is lower more advantageous to fusion process.And it is of the invention de-
Content of magnesium in gas agent can not only guarantee the degassing performance to other alloys between 20%-30%, but also can reduce
The additive amount of degasser saves cost.
It is also added into rare-earth element cerium in degasser of the invention, in alloy refining stage, degasser of the invention is added
Afterwards, for cerium on the one hand since its own plays the role of deoxidation easily in conjunction with oxygen, another aspect cerium is added to alloy ambrose alloy system
It can play the role of refining alloy crystal grain, purification crystal boundary after in column alloy melting liquid, so as to improve the comprehensive performance of alloy.From this
As can be seen that 0.1% weight is added in the refining stage for preparing ambrose alloy series alloy in the test result of the Examples 1 to 7 of invention
After the degasser of the invention of amount ratio, can by ambrose alloy series alloy melting liquid oxygen and nitrogen content be reduced to 6ppm with
Under, degasifying effect is very significant.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
