Abstract
The invention provides an aluminum alloy strip production method. The aluminum alloy strip production method comprises the steps of smelting, casting, surface milling, soaking, thermal rough rolling, thermal fine rolling, cold rolling, finishing shearing and annealing; the thermal rough rolling and the thermal fine rolling are continuously performed by adopting a multi-frame continuous mill; or the thermal rough rolling and the thermal fine rolling are separately performed by adopting a single-frame mill; or the thermal rough rolling and the thermal fine rolling are implemented by adopting a single-frame double-rolling hot mill. The aluminum alloy strip production method provided by the invention can be used for producing aluminum alloy strips in batches, is capable of realizing industrial production and is also capable of improving the microscopic structure of each rolled aluminum alloy strip so that the plasticity and the shaping property of each rolled aluminum alloy strip can be improved.
Description
Technical field
The present invention relates to the production method of a kind of aluminium alloy strips, belong to technical field of aluminum alloy technology.
Background technology
Aluminium alloy strips is a most widely used class non-ferrous metal structural material in industry, at Aeronautics and Astronautics, automobile, machine-building, boats and ships, building, finishing.And chemical industry is widely applied.Along with science and technology and the developing rapidly of industrial economy in recent years, increasing to the demand of Welded structural member, the Research on Weldability enabled aluminum alloy to is the most deeply.The extensively application of aluminium alloy promotes the development of aluminum alloy solder technology, and the application of aluminium alloy, therefore one of the solder technology of aluminium alloy just focus becoming research have been expanded again in the development of solder technology simultaneously.
The density of fine aluminium is little (ρ=2.7g/cm3), about the 1/3 of ferrum, fusing point low (660 DEG C), aluminum is face-centred cubic structure, therefore has the highest plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), it is easy to processing, can be made into various section bar, sheet material, and corrosion resistance is good；But the intensity of fine aluminium is the lowest, annealed condition σ b value is about 8kgf/mm2, therefore should not make structural material.By long-term production practices and scientific experiments, people are gradually to add alloying element and to use the methods such as heat treatment to carry out reinforced aluminum, and this has just obtained a series of aluminium alloy.Adding the alloy that certain element formed and can also have higher intensity while keeping the advantage such as fine aluminium light weight, σ b value is respectively up to 24～60kgf/mm2.Its " specific strength " (intensity and the ratio σ b/ ρ of proportion) is so made to surpass a lot of steel alloy, become preferable structural material, it is widely used in the aspects such as machine-building, Transport Machinery, dynamic power machine and aircraft industry, the fuselage of aircraft, eyelid covering, compressor etc. are often with aluminium alloy manufacture, to alleviate deadweight.Using aluminium alloy to replace the welding of steel plate materials, construction weight can alleviate more than 50%.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that the production method of a kind of aluminium alloy strips.
The production method of the aluminium alloy strips of the present invention, including melting, casting, milling face, soaking, hot roughing, hot finishing, cold rolling, finishing shearing and annealing；
Described hot roughing, hot finishing use Multi-stand continuous rolling mill to be carried out continuously；
Or described hot roughing, hot finishing uses singlestandmill separately to carry out；
Or described hot roughing, hot finishing uses single reversing hot mill with coilers located on each side of the mill to complete.
Described cold rolling carry out on the six irreversible cold-rolling mills of roller.
Described annealing is carried out in box-annealing furnace.
The production method of the aluminium alloy strips of the present invention, can be mass aluminium alloy strips, not only can carry out industrialized production, and improve the microscopic structure of institute's rolling aluminum alloy band, improve its plasticity and forming property.
