Description
Technical field
The present invention relates to the process for producing technical field of commercial aluminum alloy, be specifically related to a kind of production technique of aluminium alloy extrusions.
Background technology
In prior art, 6063 aluminium alloys are widely used in the framework of building aluminium door and window, curtain wall, in order to ensure door and window, curtain wall has high resisting wind press capacity, assembly performance, corrosion resisting property and decorate properties, to the requirement of aluminium alloy extrusions over-all properties far away higher than industry profile standard.The factor affecting 6063 Surface Quality of Aluminum Alloy Profiles is a lot, as ingot quality requirement, the design of mould, the accuracy requirement of processing all can affect the surface quality of aluminium alloy.But many times, affect the extrusion process that one of important factor of section bar surface quality is exactly section bar.The surface quality defect of general aluminium alloy extrusions has slag inclusion, cut, extruding striped, surface irregularity, hot spot, bubble etc., and these defects will affect section quality.
Summary of the invention
The object of the invention is, for above-mentioned deficiency of the prior art, to provide a kind of aluminium alloy extrusions preparation technology, it is simple that it has technique, and controllability is strong, and the aluminium alloy section surface produced is smooth, and quality is good, the feature that yield rate is high.
Object of the present invention is achieved through the following technical solutions:
A production technique for aluminium alloy extrusions, is characterized in that: comprise the following steps:
Step one, mould and die preheating: preheating in 3.5 ~ 12 hours in advance, preheating temperature is 470 ~ 500 DEG C; Container preheating: preheating in advance, preheating temperature is 440 ~ 450 DEG C; Ingot casting preheating: preheating in advance, preheating temperature is 500 ~ 530 DEG C;
Step 2: extrusion molding: ingot casting is put into container extrusion molding; Extrusion speed: middling speed should be selected to extrude, ∮ 254 × 886mm ingot casting approximately controls at 30 pieces/hour; Every root ingot casting preferably takes measures to carry out the suitable attenuation processing of speed when being expressed to and approximately remaining 300mm.Oiling swabbing must not be carried out, in order to avoid greasy dirt impurity is brought in aluminium alloy extrusions goods in extrusion process.
Step 3: quench treatment: the aluminium alloy extrusions squeezed out crosses tank quenching or online water spray quenching in the exit of described container;
Step 4: tension leveling;
Step 5: sawing is packed.
Wherein, when described mould is the new die used first, polished finish need be carried out to the working-surface of described new die and carry out nitriding treatment again after level and smooth.
Machine throughput once gone up by mould:
(1) in new mould nitrogenize first, ingot amount thrown by machine: be no more than 20 ingots (∮ 254 × 886mm);
(2) in the nitrogenize of mould second time, ingot amount thrown by machine: be no more than 35 ingots (∮ 254 × 886mm);
(3) in mould third time nitrogenize, ingot amount thrown by machine: be no more than 50 ingots (∮ 254 × 886mm);
(4) in mould more than the 4th time (containing four times) nitrogenize, ingot amount thrown by machine: be no more than 65 ingots (∮ 254 × 886mm).
Mould can significantly improve the hardness of die surface, wear resistance, seizure resistance, corrosion resistance and fatigue property by nitriding treatment, can prevent die deformation.
Wherein, described new die uses, at every turn after alkali cleaning for first four times, a nitriding treatment must be carried out, described new die nitriding treatment more than four times, carries out a nitriding treatment after changing every twice alkali cleaning into again, and each nitriding treatment of described new die forward and backward all needs carries out polished finish.
Die surface is unclean, has greasy dirt, oxide skin and Decarburized layer not removed, nitrided hard layer can be caused to spend low, adopts polished finish can remove the surface impurity of mould, strengthens nitriding result, improve nitride layer hardness.The nitriding phase of mould can be divided into carburazing period and diffusion period, constantly carries out nitriding treatment to mould, strengthens the nitrided case of mould by stages for first four times, extends the soaking time of mould, makes nitriding more even.
Wherein, when the room temperature of production plant is 10 ~ 25 DEG C, the preheating temperature of described ingot casting is: 510 DEG C ~ 530 DEG C; Temperature and the temperature of described ingot casting are inversely proportional to; When the room temperature of production plant is 25 ~ 35 DEG C, the preheating temperature of described ingot casting is: 500 ~ 510 DEG C.
The room temp of Different climate is comparatively large on the impact of ingot casting temperature, and casting temp is low, therefore needs the preheating temperature adjusting ingot casting according to the practical situation of season or room temperature.Aluminium alloy extrusions surface in extrusion process there will be white corrosion spot, there is age spot in Surface of profile after surface oxidation treatment, and this is that Surface of profile is burnt because surface temperature during profile extrusion is too high, mould and ingot casting temperature too high, can white dot be caused.Therefore temperature can not be too high.
Wherein, the quenching temperature of aluminium alloy extrusions described in described step 3 controls at 500 ~ 530 DEG C, and after described aluminum alloy section quenching, temperature controls at 50 ~ 280 DEG C.Temperature when quenching temperature refers to into tank or enters water spray quenching district, requiring on every mold in machine production process all should the section bar outlet quenching temperature of interval selective examination 3 ~ 5 ingots and temperature after quenching, guarantee to meet above-mentioned processing requirement, to improve the intensity of steel, hardness, wear resistance, fatigue strength and toughness etc.
Wherein, the sawing of described step 5 is specially carries out crop and back-end crop process to aluminium alloy extrusions, and crop length is 0.8 ~ 1.0 meter, and back-end crop length is 3.0 ~ 3.2 meters.
Wherein, also comprise aging treatment process between described step 4 and step 5, aging temp is 175 ~ 185 DEG C, and soaking time is 8 hours, to eliminate unrelieved stress, stablizes tissue and the size of aluminium alloy extrusions.
Wherein, more than the pressure of described mould, thickness is 40 ~ 42mm.Too small more than the pressure of extruding ingot casting, the oxide skin that a part participates in and impurity can flow in nib when continuously extruded, Surface of profile also can be made to scratch or cause slag inclusion.
Wherein, the amount of tension in described step 4 controls 1 ~ 1.5%, guarantees size qualification, surface do not occur orange peel phenomenon at stretching aluminium alloy extrusions.
Wherein, the main component per-cent of described aluminium alloy extrusions is: Mg 0.55 ~ 0.60%, Si 0.37 ~ 0.41%, Fe 0.13%, Cu 0.02%, Mn0.02%, Ti0.02%, Cr0.01%, Zn 0.02%, surplus is Al.
Beneficial effect of the present invention: by strictly controlling the preheating temperature of mould, container, ingot casting, through quench treatment, carrying out tension leveling, produce the aluminium alloy section surface no marking, bubble-free, smooth without extruding striped, corrosion-free point, smooth surface obtained, unit elongation and intensity high.
