Description
Technical field
The present invention relates to a kind of working method of duraluminum, relate in particular to a kind of working method of 3003 duraluminum deep-draw disks, belong to technical field of alloy material.
Background technology
3003 duraluminums 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 duraluminum is mainly used in pressure-pot, bin, chemical plant, fuel tanker, heat exchanger etc.
One Chinese patent application (publication number: CN101736182A) relate to the method for manufacture 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 deep-draw requirement of products, and its complete processing is complicated, and production cost is high.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 like the waste material in consideration ingot casting process and the generation of hot rolling process, integrated yield is merely 80%, thereby has also increased the cost of 3003 duraluminum deep-draw products.
At present adopt the method for direct cast-rolling stock to process 3003 duraluminum deep-draw products in addition; Though the production technique of this method is simple; Low cost of manufacture, but the 3003 duraluminum ubiquity deep drawabilities of producing with existing casting mode are bad, and visual appearance is poor; Defective such as easy to crack is difficult to satisfy the user for 3003 duraluminum deep-draw requirement of products.
Summary of the invention
The objective of the invention is provides the working method of the 3003 duraluminum deep-draw disks that a kind of technical process is simple, yield rate is high, cost is low, deep drawability is good to the existing in prior technology defective.
The object of the invention can be realized through following technical proposal: a kind of working method of 3003 duraluminum 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 duraluminum 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 processed through common casting; Concrete technology is as follows: according to processing 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.
