B. aluminum profile enters the work belt molding of mold under the effect of the pressure, and aluminum profile after molding is flowed from discharge port
Out；
C. in the surface of discharge port, processing mills out air slot, and the top of air slot is connected with nitrogen conduit, in extruded aluminium
While profile, the external nitrogen storage tank of nitrogen conduit is going out aluminum profile to introduce the cavity that nitrogen is full of the discharge hole
Expect moment starvation, avoids the occurrence of alumina particle；
D. the obtained aluminium profile product of step C is quenched, quenching mode is strong wind cooling, is carried out to aluminum profile
Alignment processing, aging time 2-5h ultimately form the aluminium bar material product of certain size.
Further, temperature is maintained at 520-540 DEG C of range when extrusion aluminum-type material in step C.
Further, extrusion speed 2-10mm/s in step A.
Further, in step D, wind speed requires to be maintained at 3m/s or more when strong wind cooling.
Further, in step D, the alignment deformation quantity of aluminum profile is about 0.2%.
The beneficial effects of the present invention are: the extruding production technology that nitrogen protection of the invention discharges, by discharge hole
Inert nitrogen gas is imported in cavity, reduces the oxygen content around discharge port, makes the high temperature profile for just going out product moulding chamber
Under nitrogen protection environment, the generation of oxidation reaction is avoided, to achieve the purpose that reduce alumina particle, process flow letter
Single, operability is high.
