Embodiment 1

[0024] Embodiment 1, aluminum alloy rolled pattern plate and production method thereof,

[0025] (1) The composition of the aluminum alloy rolled checkered plate, expressed in parts by weight, is 0.001 part of Si, 0.50 part of Fe, 0.05 part of Cu, 1.0 part of Mn, 0.001 part of Mg, 0.1 part of Ni, 0.05 part of Zn, 0.001 part of Ti and the rest Amount of Al, a total of 100 parts;

[0026] During production, the mixed metal is smelted at 770°C for 5 minutes. When the charge is completely melted and reaches the melting temperature range, the slag is removed, and then thoroughly stirred. After the thorough stirring is ensured, when the melt temperature reaches 730°C, samples are taken and tested. Whether the ingredients are qualified; and carry out the first stirring at a speed of 50 rpm, stirring for 5 minutes; after the first stirring, stay for 10-15 minutes, wait for the charge to be fully dissolved, adjust the temperature to 740-760°C, and then stir for 5-10 minutes , to obtai...

Embodiment 2

[0031] Embodiment 2, aluminum alloy rolled checkered plate and production method thereof, the same as embodiment 1 will not be repeated, the difference is:

[0032] (1) Composition: 0.20 parts of Si, 0.001 parts of Fe, 0.12 parts of Cu, 1.3 parts of Mn, 0.05 parts of Mg, 0.001 parts of Ni, 0.001 parts of Zn, 0.03 parts of Ti and the balance Al, totaling 100 parts; Melting at ℃ for 5 minutes;

[0033] (2) Refining with nitrogen and chlorine mixed gas for 20 minutes under the condition of 740 ° C, and standing for 9 hours, the standing temperature is 750 ° C; the thickness of the product is 7.0 ~ 7.8 mm under the condition of the front box temperature of 715 ° C and the speed of 1000 mm / min. rough material;

[0034] (3) The rough material is rolled to a thickness of 2.50mm through 2 to 4 passes of a four-fold cold rolling mill at a medium temperature of 60°C; the rolling speed is 100m / min;

[0035] (4> After bending and straightening, quench at 410°C for 10h.

Embodiment 3

[0036] Embodiment three, aluminum alloy rolled checkered plate and its production method, the same as embodiment one will not be repeated, the difference is:

[0037] (1) Composition: 0.005 parts of Si, 0.45 parts of Fe, 0.10 parts of Cu, 1.2 parts of Mn, 0.005 parts of Mg, 0.005 parts of Ni, 0.04 parts of Zn, 0.003 parts of Ti and the balance of Al and unavoidable impurities, totaling 100 parts; Melt the mixture at 760°C for 18 minutes;

[0038] (2) Refining at 750°C for 18 minutes, standing still for 11 hours, the standing temperature is 740°C. Under the condition of head box temperature of 700℃ and speed of 150mm / min, blanks of 7.0-7.8mm are produced;

[0039] (3) Rolled to 2.0-3.0mm by four-fold cold rolling mill; rolling speed is 10m / min;

Abstract

The invention relates to an aluminum alloy rolled plate and a production method thereof. The plate comprises the components of Si, Fe, Cu, Mn, Mg, Ni, Zn, Ti and Al. While in production, all components are mixed and melted at a temperature of between 750 and 770 DEG C, are subjected to slagging-off, refining and standing; and blank materials with the thickness of between 7.0 and 7.8mm are produced by casting and rolling; the thickness of the blank materials are rolled at an intermediate temperature to between 2.0 and 3.0mm by a four-high cold roll, and the blank materials are rolled into pattern boards or mirror boards; finally, the boards are subjected to stretch bending straightening and quenching. The boards in the invention are low in density and almost the same as aluminum in density, have the strength between 140 and 300MPa, and are strong in corrosion resistance; the rolled pattern boards are good in skid resistant performance, thereby meeting the use requirements of aluminum alloy floor boards in special fields(such as air planes); the aluminum alloy mirror boards have the advantages of stable performance, durability, light weight, good water proof and fire proof performances and wide application, and can be applied to indoor and outdoor decorations and lighting, etc. The method has the advantages of simplified process, low production cost and easy promotion and application.

Description

1. Technical field: [0001] The invention relates to an aluminum alloy plate and a production method thereof, in particular to an aluminum alloy rolled plate and a production method thereof. 2. Background technology: [0002] With the advancement of science and technology, aluminum alloy sheets are used more and more widely, not only in people's daily life, but also in industry, agriculture, construction, chemical industry, transportation, etc., and some are even used on space shuttles . For example, the current aviation aircraft has the advantages of high speed, high angle and high maneuverability during flight. In order to ensure the stability and safety of the aircraft, the aluminum alloy floor for aircraft has been proposed with light density, high strength, corrosion resistance, Anti-slip and anti-splashing water flow and other requirements. [0003] The invention patent with the application number 200710072126.X discloses an aluminum alloy anti-slip checkered plate fo...
