Abstract
The present invention relates to casting manufacture field, there is provided a kind of casting method of copper-alloy casting, mainly comprise the following steps：Cu, the Zr of 0.02-0.10% are put into crucible, protective gas is filled with after vacuumizing, directly heated, until metal molten；After after above-mentioned metal all fusing, the Al, the Fe of 3.0-4.5%, the Mn of 0.30-1.4% of 8.5-10.5% are added, the Cr of the Zn and 0.05-0.15% of the Pb of the Ni of 1.1%-2.8%, 0.05%-0.08%, 1.0-2.0%, stir, continue to heat up, untill being completely melt；After slagging-off, refined, be incubated 5-10 minutes, 10-15 minutes is stood after refining；Skim, deaerate, except removing dross after, molten metal is poured into silicasol case, after being poured, Slow cooling, take out casting.The invention has the advantage that and chromium and zirconium added in the manufacturing process of casting, substantially increases the hardness and wearability of copper, can guarantee that casting is indeformable；Alloying component and proportioning are further optimized, the forming quality of casting can be improved, make casting mechanical performance more stable.
Description
Technical field
The invention belongs to casting manufacture field, more particularly, to a kind of casting method of copper-alloy casting.
Background technology
Casting is the metal forming object obtained with various casting methods, i.e., the liquid metal smelted, with cast, pressure
Penetrate, suck or other casting methods are injected in preprepared casting mold, after cooling through following process means such as polishings after,
It is resulting with definite shape, the object of size and performance.Casting is divided into cast steel by the difference of its metal material used
Part, ironcasting, copper casting, aluminum casting, casting magnesium part, casting zinc part, casting titanium part etc.；And can be by its chemistry per class casting
Composition or metallographic structure are further separated into different species, and such as ironcasting can be divided into gray iron casting, nodular iron casting, compacted ink
Ironcasting, mitis metal, alloy iron casting etc.；Alloy-steel casting is superior because of its various aspects of performance, using quite varied.
The content of the invention
It is an object of the invention to provide a kind of casting method of copper-alloy casting, technical process is simple, the casting quality for obtaining
It is good.
To realize above-mentioned goal of the invention, technical scheme is as follows：
A kind of casting method of copper-alloy casting, the copper alloy of the casting is made up of the component of following weight percentage：
Al8.5-10.5%, Fe3.0-4.5%, Mn0.30-1.4%, Ni 1.1%-2.8%, Pb0.05%-0.08%, Zr0.02-0.10%, Zn
1.0-2.0%, Cr0.05-0.15%, balance of Cu；
Casting method comprises the following steps：
1) according to said components and its weight/mass percentage composition dispensing, then each component is respectively dried standby；
2) by Cu, the Zr of 0.02-0.10% is put into crucible, and protective gas is filled with after vacuumizing, and is directly heated, until
Metal molten；
3) after after above-mentioned metal all fusing, Al, the Fe of 3.0-4.5%, the Mn of 0.30-1.4% of 8.5-10.5% are added,
The Cr of the Zn and 0.05-0.15% of the Pb of the Ni of 1.1%-2.8%, 0.05%-0.08%, 1.0-2.0%, stirs,
Continue to heat up, untill being completely melt；
4) after removing the gred, refined, be incubated 5-10 minutes, 10-15 minutes is stood after refining；
5) skim, deaerate, except removing dross after, molten metal is poured into silicasol case, after being poured, slowly
Cooling, takes out casting.
Preferably, step 2) in protective gas be argon gas.
Preferably, step 5) in the cast of molten metal carry out under vacuum conditions.
The present invention has the advantages and positive effects that：Chromium and zirconium are added in the manufacturing process of casting, is substantially increased
The hardness and wearability of copper, can guarantee that casting is indeformable；Alloying component and proportioning are further optimized, casting can be improved
The forming quality of part, makes casting mechanical performance more stable.
