Description
Technical field
The present invention relates to aluminium alloy smelting system of processing technical field more particularly to a kind of aluminium alloy smelting system of processing and
Its production technology.
Background technique
The chemical analysis of 6063 aluminium alloys is the silicon of 0.2-0.6% in GB/T5237-93 standard, the magnesium of 0.45-0.9%,
The highest limitation of iron is 0.35%, remaining impurity element (Cu, Mn, Zr, Cr etc.) is respectively less than 0.1%.This compositional ranges is very wide, it
There are also very large option leeway.6063 aluminium alloys are to belong to the heat-treatable strengthened type aluminium alloy of Al-Si-Mg series, in AL-Mg-Si group
At ternary system in, without ternary compound, only there are two binary compound Mg2Si and Mg2Al3, with α (Al)-Mg2Si puppet two
First section is boundary, constitutes two ternary systems, α (Al)-Mg2) and α (Al)-Mg Si-(Si2Si-Mg2Al3.In Al-Mg-Si system
In alloy, main hardening constituent is Mg2Si, alloy is in quenching, the Mg that is solid-solution in matrix2Si is more, the alloy strength after timeliness
It is higher, conversely, it is then lower, in α (Al)-Mg2On Si puppet binary phase diagraml, eutectic temperature is 595 DEG C, Mg2The maxima solubility of Si
It is 1.85%, is 1.05% at 500 DEG C, it can be seen that, temperature is to Mg2Solid solubility of the Si in Al influences very big, hardening heat
Higher, the intensity after timeliness is higher, conversely, hardening heat is lower, the intensity after timeliness is lower.The production of some aluminium section bar plants
Profile chemical analysis is qualified, and intensity does not reach requirement but, and reason is exactly that aluminium handful heating temperature is not enough or cold in heat outside, causes profile
Hardening heat is too low caused.In Al-Mg-Si alloy series, hardening constituent Mg2The magnesium silicon weight ratio of Si is 1.73, if alloy
In have superfluous magnesium (i.e. Mg:Si > 1.73), magnesium can reduce Mg2Solid solubility of the Si in aluminium, to reduce Mg2Si is in the alloy
Strengthening effect.If there is superfluous silicon in alloy, i.e. Mg:Si < 1.73, then silicon is to Mg2Solid solubility of the Si in aluminium does not have
It influences, it can be seen that, to obtain the alloy of higher-strength, it is necessary to Mg:Si < 1.73.
Existing aluminium alloy is not handled aluminium scrap in melting, is caused the final product quality of aluminium alloy not high, is
