Abstract
The invention discloses a manufacturing method of 5754 aluminium alloy blank through casting machine, which comprises the following steps: fusing alloy aluminium liquid; refining; filtering; casting; obtaining the cast coil or board.
Description
Technical field
The present invention relates to the aluminium processing technique field, specifically utilize casting and rolling machine to produce the production method of 5754 aluminum alloy blanks.
Background technology
At present; ingot casting hot rolling and two kinds of production methods of Hezlet are generally adopted in the production of 5754 aluminum alloy blanks; these two kinds of method facility investments are huge; technical requirements and production cost are higher; especially ingot casting hot rolling method is all very high aspect energy consumption and production cost; and the handiness of producing is relatively poor, relatively is fit to large-scale production in batches.Original ingot casting hot rolling production technique is: melting → refining → ingot casting → homogenizing sawing → mill face → heating → hot rolling → batch → detect → finished product.
Summary of the invention
The purpose of this invention is to provide a kind ofly can reduce production costs, the energy that economizes on resources, shorten the production cycle, the convenient casting and rolling machine of producing that utilizes produces the production method of 5754 aluminum alloy blanks.
Technical scheme of the present invention is to utilize casting and rolling machine to produce 5754 aluminum alloy blanks, and its production technique is as follows: alloy aluminum liquid through melting, concise, grain refining, filtration after, enter the casting and rolling machine casting and produce casting volume or plate.
Operational path:
Melting → refining → casting → batch → detect → finished product
Concrete production method is:
Electrolytic aluminium liquid, aluminium ingot or processing waste (aluminium waste) and high pure magnesium ingot, wherein about 70～80%, aluminium ingot of electrolytic aluminium liquid or processing waste 20～30%, high pure magnesium ingot 3.2%, after adding the smelting furnace fusing, detect chemical ingredients, Mg content is controlled in 2.8～3.2% scopes in the chemical ingredients, after chemical ingredients is qualified, carry out furnace refining, feed high-purity N
2(purity 99.999%) and refining agent (addition be aluminium liquid total amount 1～2%) carry out refining, and refining temperature enters then and leaves standstill stove below 750 ℃, add grain-refining agent aluminium titanium boron wire (addition is 1.5～2%), carry out grain refining, online N
2(purity 99.999%) degasification, filtration, casting and rolling machine are rolling, 670～685 ℃ of preceding oven temperature, degree, and roll speed is 0.7～0.8m/min, batches then, checks, and can become the work in-process of finished product or next procedure.
The mechanical property of product of the present invention:
| State | Tensile strength (MPa) | Unit elongation (%) |
| O | 190～205 | ≥12 |
| H24 | 240～285 | ≥6 |
| H18 | ≥320 | ≤3 |
The positively effect that the present invention brought is: reduce by 600～800 yuan/ton than existing ingot casting hot-rolling method production cost; Product performance are near hot-rolled product, and its Production Flow Chart is short, and energy consumption is low, and cost is low, yield rate is high, and production method is easy.
