Abstract

The invention discloses an aluminum alloy castings heat treatment technology. The heat treatment technology comprises the following steps: a) putting the casted aluminum alloy castings in a normalizing furnace, heating the aluminum alloy castings to the temperature of 880-920 DEG C, and insulating the aluminum alloy castings for 4 h; b) directly putting the castings in quenching oil at the temperature of 50-80 DEG C for quenching treatment for 2 minutes; and c) tempering the castings at the temperature of 220-270 DEG C and insulating for 3-6 h. The provided aluminum alloy castings heat treatment technology is characterized in that the castings are taken out from a casting machine, and then is subjected to quenching treatment, and then is subjected to tempering and insulating treatment. The obtained aluminum alloy castings have the advantages of high intensity, good toughness, and difficult fracture.

Description

Aluminium alloy castings Technology for Heating Processing
Technical field
The invention belongs to non-ferrous metal field, particularly relate to aluminium alloy castings Technology for Heating Processing.
Background technology
Aluminium alloy is except having that density is little, in addition to good conductivity, heat conductivity advantage high, erosion-resisting, also there is specific strength and specific stiffness is high, processing and the feature such as processability is good, therefore do structural material with aluminium alloy can significantly alleviate product weight and increase structural stability, be used widely aborning.Especially as auto body sheet aluminium alloy, it is possible not only to alleviate tare, the energy consumption of automobile can be significantly reduced simultaneously.But, although aluminium alloy has higher intensity, but its relatively low fracture ductility restricts its application.Traditional Technology for Heating Processing, although improve the fracture ductility of aluminium alloy to a certain extent, but sacrifice the intensity that aluminium alloy is certain.
Therefore, the intensity and the fracture ductility that improve aluminium alloy become the problem that investigation of materials scholar needs urgently to solve the most simultaneously.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of aluminium alloy castings Technology for Heating Processing, and the aluminium alloy castings intensity using this PROCESS FOR TREATMENT is higher, not easy fracture.
For achieving the above object, the invention provides a kind of aluminium alloy castings Technology for Heating Processing, comprise the steps:
A, aluminium alloy castings casting completed are placed in normalizing furnace, are warming up to 880 DEG C-920 DEG C, are incubated 4 hours;
B, foundry goods is directly placed in 50-80 DEG C of quenching oil and carries out Quenching Treatment, 2 minutes cool times;
C, by foundry goods 220~270 DEG C tempering insulation 3~6 hours,.
Further, the temperature of normalizing furnace is warming up to 900 DEG C.
Further, the temperature of quenching oil is 65 DEG C.
The invention has the beneficial effects as follows: the aluminum alloy heat processing method that the present invention provides, be foundry goods is taken out from casting machine after, just horse back carries out Quenching Treatment, then carries out tempering isothermal holding.The aluminium alloy castings intensity obtained is high, good toughness, and not easy fracture.
Detailed description of the invention
The technical scheme that the present invention provides is a kind of aluminium alloy castings Technology for Heating Processing, comprises the steps:
A, aluminium alloy castings casting completed are placed in normalizing furnace, are warming up to 880 DEG C-920 DEG C, are incubated 4 hours;
B, foundry goods is directly placed in 50-80 DEG C of quenching oil and carries out Quenching Treatment, 2 minutes cool times;
C, by foundry goods 220~270 DEG C tempering insulation 3~6 hours,.
Further, the temperature of normalizing furnace is warming up to 900 DEG C.
Further, the temperature of quenching oil is 65 DEG C.
The aluminum alloy heat processing method that the present invention provides, be foundry goods is taken out from casting machine after, just horse back carries out Quenching Treatment, then carries out tempering isothermal holding.The aluminium alloy castings intensity obtained is high, good toughness, and not easy fracture.
