Description
Technical field
The present invention relates to a kind of production method of aluminium alloy, relate in particular to a kind of production method of 3003 aluminium alloy deep-draw disks, belong to technical field of alloy material.
Background technology
3003 aluminium alloys belong to a kind of in the Al-Mn line aluminium alloy, good erosion resistance are arranged, intensity is lower, plasticity is high, forming property is good, and welding property is good.This aluminium alloy is mainly used in pressure-pot, bin, chemical industry equipment, fuel tanker, heat exchanger etc.
Chinese patent application (publication number: CN101736182A) relate to the manufacture method of hand phone battery case with 3003 aluminium alloy strips, this method comprise the batching and through melting, casting, homogenizing annealing, hot rolling and cold-rolling treatment.Though the 3003 aluminium alloy strips structure properties that this method is produced are good, its tensile strength, unit elongation and earing rate all can reach the requirement of deep-draw product, its complete processing complexity, production cost height.And metal loss is 2.5% during the hot rolling blank melting, and the crop end amount is 6%, and the face amount of milling is 5.5%, and as the waste material in consideration ingot casting process and the generation of hot rolling process, integrated yield only is 80%, thereby has also increased the cost of 3003 aluminium alloy deep-draw products.
At present adopt the method for direct cast-rolling stock to make 3003 aluminium alloy deep-draw products in addition, though the production technique of this method is simple, low cost of manufacture, but it is bad with the 3003 aluminium alloy ubiquity deep drawabilities that existing casting mode is produced, visual appearance is poor, defective such as easy to crack is difficult to satisfy the requirement of user for 3003 aluminium alloy deep-draw products.
Summary of the invention
The objective of the invention is at the existing in prior technology defective, the production method of the 3003 aluminium alloy deep-draw disks that a kind of technical process is simple, yield rate is high, cost is low, deep drawability is good is provided.
Purpose of the present invention can realize by following technical proposal: a kind of production method of 3003 aluminium alloy deep-draw disks, and this method may further comprise the steps:
A, casting: it is 3003 aluminum alloy plate materials of 5.0-8.0mm that the back casting of 3003 al alloy components batching is become thickness, is the cold rolling processing of 12%-40% through the cold deformation working modulus then;
B, homogenizing are handled: 3003 aluminum alloy plate materials after the above-mentioned cold rolling processing are carried out homogenizing handle, homogenization temperature is 540-600 ℃, and soaking time is 10-30 hour;
C, cold rolling processing once more: 3003 aluminum alloy plate materials after the above-mentioned homogenizing processing are carried out once more cold rolling processing, and cold rolling once more processing adopts the 2-5 passage rolling;
D, stamping-out, anneal: 3003 aluminum alloy plate materials stamping-outs after the above-mentioned cold rolling once more processing are become disk, then disk is carried out getting 3003 aluminium alloy deep-draw disk finished products after the anneal, annealing temperature is 500-600 ℃, and soaking time is 0.5-5 hour.
3003 aluminum alloy plate materials of the present invention can be made by common casting, concrete technology is as follows: according to making aluminium ingot and master alloy after the 3003 al alloy components batching, aluminium ingot is added in the crucible electrical resistance furnace, when treating the aluminium ingot fusing, add master alloy and stirring; Add Mg and Zn then, slag hitting, refining; Stirring is also left standstill casting in pig mold; With the aluminium alloy cast ingot hot rolling of above-mentioned casting, cold rolling 3003 aluminum alloy plate materials that roll into.
