Abstract

The present invention relates to a kind of cable armouring to protect thin wall type flexible pipe Al-alloy material, is made by the raw material of following mass percent：Mn 0.10%, Si 0.25%, Fe 0.40%, Cu 0.10%, Zn 0.10%, Cr 0.15-0.35%, Mg 2.4-2.6%, remaining is Al.Its preparation technology includes：Matched according to above-mentioned raw metal content, aluminium alloy cast ingot is made in mixing founding, and aluminium alloy cast ingot is heated into 590 ~ 610 DEG C, insulation, carries out homogenizing annealing 15h；Then aluminium alloy cast ingot is hot-rolled down into 5 ~ 6mm to batch, aluminum alloy hot rolling coiled material is made；Cold rolling is carried out to aluminum alloy hot rolling coiled material, is controlled before final cold rolling passage by required specification trimming, the cold roling reduction of final passage in 25 ~ 30%, 0.6 ~ 1.0mm of rolling thickness, the aluminium rolled is involved in into furnace annealing, finally the band of specification needed for cutting.The aluminum alloy materials plasticity of the present invention is good, and easily processed into type, density is low, good mechanical property, and 220-240MPa of tensile strength, elongation after fracture reaches more than 10%, and the protection of cable armouring is fully achieved with requiring.

Description

A kind of cable armouring protects thin wall type flexible pipe Al-alloy material

Technical field

The present invention relates to aluminum alloy materials technical field, and in particular to a kind of cable armouring protection thin wall type flexible pipe is closed with aluminium Golden new material.

Background technology

Pillar lightweight is realized, is one of maximally effective approach for saving the energy.Existing white rust steel pillar weight compares Greatly, steel are substituted with aluminium alloy strips, weight can reduce more than 50%.

It is contemplated that finding a kind of high intensity, good moldability, aluminium alloy strips in light weight substitutes steel.

The content of the invention

It is an object of the invention to：For technical problem set forth above, there is provided a kind of cable armouring protection thin wall type is soft Effective Al-alloy material.

The present invention is achieved by the following technical solutions：

A kind of cable armouring protects thin wall type flexible pipe Al-alloy material, is made by the raw material of following mass percent：Mn 0.10%th, Si 0.25%, Fe 0.40%, Cu 0.10%, Zn 0.10%, Cr 0.15-0.35%, Mg 2.4-2.6%, remaining is Al。

A kind of preparation technology of cable armouring protection thin wall type flexible pipe Al-alloy material as described above, including it is as follows Step：

Matched according to above-mentioned raw metal content, melting, aluminium alloy cast ingot is made；To aluminium alloy cast ingot sawing, milling face, then 480 ~ 520 DEG C are heated to, is incubated 10 ~ 12h；Then aluminium alloy cast ingot is hot-rolled down into 5 ~ 6mm to batch, aluminum alloy hot rolling volume is made Material；Cold rolling is carried out to aluminum alloy hot rolling coiled material, required specification trimming, the cold roling reduction of final passage are pressed before final cold rolling passage Between 25% ~ 30%, final rolling thickness is 0.6 ~ 1.0mm for control, the aluminium rolled is involved in into furnace annealing, annealing process is selected 400 DEG C, 10h is incubated, obtains required performance, finally the band of specification needed for cutting.

In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：

1st, aluminum alloy materials plasticity produced by the present invention is good, and easily processed into type, density is low, can be effective using aluminum alloy materials Mitigate the weight of pillar, at the same time it can also reduce enterprise's materials cost and engineering manufacturing expense, improve economic results in society.

2nd, aluminium sheet produced by the present invention, its satisfactory mechanical property, tensile strength is 220 to elongation of between 240MPa, having no progeny Rate reaches more than 10%, and the protection of cable armouring is fully achieved with requiring.
