Technical field
The present invention relates to a kind of method of manufacture of tangerine line oxidation plate, particularly a kind of method of manufacture of high-quality surface tangerine line oxidation plate.
Background technology
The tangerine line oxidation strip material that is used to produce refrigerator ice cabinet in the market generally adopts 1145 and 1060 alloys.Adopt 1145 alloy production refrigerator ice cabinets more serious with tangerine line oxidation strip material aberration after carrying out oxidation, surface brightness is not enough, and 180 ° of bending easy of crack.Adopt 1060 alloy production refrigerator ice cabinets lighter with tangerine line oxidation strip material aberration after carrying out oxidation; But the surface of tangerine line oxidation strip material is easy to generate little black silk, the black line defective of small and dispersed shape, causes problems such as production efficiency and the yield rate of the finished product is low.
Summary of the invention
Goal of the invention: the objective of the invention is deficiency, a kind of better surface quality tangerine line oxidation board fabrication method is provided to prior art.
Technical scheme: a kind of method of manufacture of high-quality surface tangerine line oxidation plate, the key step of this method is following:
1) with 1070 alloy material meltings, casting, sotck thinkness is 6.2mm～6.8mm after the casting;
2) sotck thinkness is cold-rolled to behind 0.3～0.6mm slitting and cuts edge, and carry out the finished product low-temperature annealing, carry out subsequent steps such as conventional embossing, degreasing again.
The moity of said 1070 alloy materials and mass percent are: Si0.05～0.09%, Fe0.11～0.18%, Cu are no more than 0.01%, Mn is no more than 0.01%, Mg is no more than 0.01%, Cr is no more than 0.01%, Zn is no more than 0.04%, Ti is no more than 0.03%, surplus Al.
Annealing process is that blank is incubated 2～6 hours and carries out low-temperature annealing oil removing purge under 200 ℃ of conditions, is warming up under 250～275 ℃ of conditions again and is incubated 17～24 hours.
Beneficial effect: advantage of the present invention is to adopt 1070 alloy cast-rolling stocks of specific components content to produce high-quality surface tangerine line oxidation strip material; 1070 alloys of specific components content have been gathered 1145 alloys and 1060 alloys advantage separately; Not only surperficial no color differnece, luminance brightness are good, and plasticity also is higher than other alloy, help follow-up embossing processing more; Surface detail is more attractive in appearance after making its band embossing; The little black silk of the no disperse shape in surface, black line phenomenon are effectively enhanced productivity and yield rate simultaneously, and final product quality and performance index satisfy the specification of quality of high-quality surface tangerine line oxidation plate fully.
Embodiment
Below in conjunction with specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
A kind of method of manufacture of high-quality surface tangerine line oxidation plate, concrete steps are following:
1) melting: will be no more than 0.01% by 1070 alloy material melting: Si0.05～0.09%, Fe0.11～0.18%, the Cu that following moity and mass percent proportioning form, Mn is no more than 0.01%, Mg is no more than 0.01%, Cr is no more than 0.01%, Zn is no more than 0.04%, Ti is no more than 0.03%, surplus Al.Adopt the permanent magnetism stirring technique that melt is stirred, smelting temperature is no more than 755 ℃, leads furnace temperature at 750 ± 5 ℃.
2) casting: adopt the rotation air blast to carry out online degasification; 40PPi+50PPi is board-like, and the double-stage filtering mode is carried out purifying treatment to melt; Guarantee hydrogen richness≤0.15ml/100g in the melt, according to the strict add-on of controlling the alterant aluminium titanium boron wire of the ratio of material quantity quality 0.2%.Riser and adopt little casting district and low roll speed when producing reducing melt the separating out of supersaturated solid solution when solidifying, and can obtain the tiny metallurgy tissue of uniform crystal particles, and sotck thinkness is 6.2mm～6.8mm after the casting.
3) cold rolling: must change roll during cold rolling cogging, and it is wiped clearly with alcohol or acetone, during cogging to aluminium volume surface inspection and purging.During rolling first passage, working modulus guarantees the big working modulus 40%～55%, obtains calendering and broken to guarantee casting plate central core tissue, obtains uniform interior tissue; The final pass working modulus can suitably remain between 27%～38%, to guarantee milled sheet shape and surface quality.When being rolling to 0.3mm～0.6mm through 4～5 passage thickness, behind the intercooling of 24h, to the arrangement of cutting edge of its slitting.Also must change roll when slitting is cut edge, and it is wiped clearly with alcohol or acetone.
4) annealing: under 200 ℃ of conditions, be incubated 2～6 hours and carry out low-temperature annealing oil removing purge, be warming up to again under 250～275 ℃ of conditions and be incubated 17～24 hours.The annealing back is cold fully just can carry out subsequent step.
5) embossing.
6) degreasing: the groove technology of joining of degreasing tank is: in degreasing tank, add 2/3 water, add tsp according to the ratio of 20g/L, add water to the upper limit position of tank liquor again, steam heating to 50 ℃.
7) anodic oxidation: band is placed on the central authorities of oxidation trough, guarantees that it equates with the distance of negative plate, promptly get high-quality surface tangerine line oxidation plate of the present invention after the oxidation.The groove technology of joining of oxidation trough is: in oxidation trough, add 3/4 water, start and stir and refrigerating unit, slowly add sulfuric acid.Sulfuric acid concentration is 100～250g/L in the oxidation trough, and current density is 1.0～1.8A/dm
2, oxidation rate is 3～8m/min.
After making high-quality surface tangerine line oxidation plate of the present invention, tackle its visual appearance and surface quality and check, when wherein checking surface and oil contaminant, drip 3～5 65 at aluminium foil surface
#Pairing oil uses absorbent cotton in the place's wiping of aluminium foil surface oil dripping once then, sees whether absorbent cotton has black greasy dirt or aluminium powder etc.
