Abstract
The invention discloses a method for smelting magnesium beryllium master alloy, which employs the following procedures: 1) magnesium is arranged at the bottom of a crucible and then an appropriate amount of beryllium powders is applied over the magnesium; 2) the crucible is arranged in a medium frequency vacuum furnace; 3) argon is introduced into the medium frequency vacuum furnace, the medium frequency vacuum furnace is started up and the argon is heated up until the temperature rises to 800 -1400 DEG C; 4) a prearranged shuttering is arranged in the medium frequency vacuum furnace, a rotating handle outside the medium frequency vacuum furnace is manipulated to pour magnesium and beryllium liquation into the shuttering for casting moulding. The method introduces argon in the process of heating the magnesium and the beryllium and burning point of the magnesium is dramatically raised in the absence of oxygen; therefore, the magnesium and the beryllium are melted at first without being burnt, thereby realizing the objective of casting the master alloy.
Description
Affiliated technical field
The invention belongs to a kind of smelting process of alloy, specifically the smelting process of magnesium beryllium alloy.
Background technology
Magnesium is a kind of light material, and its density is also lower than aluminium, is mainly used in component such as aerospace, ocean machinery and computer to dissipate heat sheet.Magnesium intensity is low, and burning-point is 500 ℃, and fusing point is 650 ℃, and this elder generation fires the characteristics that afterwards melt and is difficult to pour into a mould component, does not bring into play its low density advantage.In fusing, also can be along with the continuous rising of temperature is progressively gasified until detonation.Beryllium is a kind of lightweight rare metal, has two kinds of crystalline structure, and density is low, and rapid heat dissipation.The intensity of beryllium is bigger, has surpassed titanium alloy and aluminium alloy, and is bigger four times than steel, and keeping due intensity in high temperature.When magnesium and beryllium are fused to a time-out, can obtain magnesium beryllium mother alloy of different nature according to different ratios, and their burning-point and fusing point are brought up to more than 650 ℃.As add different metal elements, can obtain the lightweight special metals material of characteristics separately.But at present and since magnesium, beryllium separately characteristics there are differences, cause the two to be difficult to molten mutually and smelt into mother alloy.Therefore, in the prior art, magnesium beryllium mother alloy is not arranged as yet.
Summary of the invention
The present invention's purpose is to overcome the above-mentioned deficiency of prior art, and a kind of smelting process of magnesium beryllium mother alloy is provided, and it is easy to operate, highly effective.
For reaching above-mentioned purpose, the present invention takes following processing method:
1) magnesium is put into the ceramic crucible bottom, then, on magnesium, put an amount of beryllium powder;
2) crucible is put into the intermediate frequency vacuum oven;
3) argon gas is imported in the intermediate frequency vacuum oven, started the intermediate frequency vacuum oven and be heated to 800 ℃～1400 ℃ and stop;
4) be provided with in the intermediate frequency vacuum oven and preset formwork, handle the outer turning handle of intermediate frequency vacuum oven, pour in the formwork magnesium in the crucible, beryllium liquation into cast molding.
The present invention takes above-mentioned processing method, has following beneficial effect: the present invention imports argon gas in magnesium, beryllium heat-processed, is not having under the state of oxygen, and the burning-point of magnesium improves greatly.Like this, just make the fusing earlier under non-combustible situation of magnesium, beryllium, thereby realize being cast into the purpose of mother alloy.
Embodiment
Introduce the present invention in detail below in conjunction with embodiment.
Embodiment:
The present invention takes following processing method:
1) 1000 gram magnesium is put into the ceramic crucible bottom, then, on magnesium, put 2000 gram beryllium powder;
2) crucible is put into the intermediate frequency vacuum oven;
3) argon gas is imported in the intermediate frequency vacuum oven, started the intermediate frequency vacuum oven and be heated to 800 ℃～1400 ℃ and stop;
4) be provided with in the intermediate frequency vacuum oven and preset formwork, handle the outer turning handle of intermediate frequency vacuum oven, the magnesium in the crucible, beryllium liquation are poured in the formwork, realize cast molding.
In the present invention, the intermediate frequency vacuum oven is used for the cooling to the intermediate frequency vacuum oven by circulating pipe and the external tank of water pump.The intermediate frequency vacuum oven also is circumscribed with dust purification, toxic gas refining plant.
