About aluminum, we should first think of the cold rolling process. The rolling process below the recrystallization temperature of metals and alloys is called cold rolling. (Aluminum plate manufacturers)Cold rolling, although due to metal deformation heat and friction heat, but also make the rolling temperature, has a certain role in recovery, but in the cold rolling process plays a major role is cold hardening (work hardening).
Compared with the hot-rolled cold rolling(aluminium sheet plate) is the main feature is the thickness of the thin strip can be obtained. The thickness of the hot-rolled slab is usually 6 to 8 mm. The minimum thickness is 2.5mm-3.0mm. It is difficult to continue rolling to a thinner thickness due to the large temperature drop of the rolled material during the hot rolling and the cold rolling can easily make the rolling thinning possible. Typically, the cold rolling mill can be rolled to 0.5-4.5mm, more advanced cold rolling mill, can be rolled out of the thickness of 0.1mm-0.2mm of special thin or thick foil.
Compared with the hot-rolled cold rolling(aluminium sheet 5083) is the main feature of the size can be rolled out of precision, uniform thickness, flatness and surface gloss, product performance and good surface quality of the product. Because the cold rolling mill has higher precision than the hot rolling mill, the comprehensive automatic control level of the cold rolling(aluminium sheet in china) mill is high, for example, the advanced cold rolling mill is equipped with such devices as thickness and plate type automatic control. In addition, the use of higher cold-rolled roll can roll out a high surface quality and mirror aluminum and so on.

Thickness tolerance of aluminum plate---Haomei aluminum sheet
The thickness of the aluminum plate is one of the important properties of the material. Aluminum in the technical standards are provided for the nominal thickness and the actual thickness of the allowable difference between the difference called the thickness deviation. Aluminum and aluminum alloy military aluminum requirements of most of the negative deviation, while the civilian aluminum plate, some require positive and negative deviation.
Another requirement for the thickness of the cold rolled aluminium plate is the uniformity of the thickness. In the same aluminum sheet, if the thickness is not uniform, the thickness difference is called the same plate difference.

Application of 5-series marine aluminum plate
Marine aluminum according to the manufacturing process can be divided into deformed aluminum and cast aluminum, due to the marine aluminum strength, corrosion resistance and weldability and other special requirements, so more choice of marine aluminum aluminum - magnesium alloy, aluminum - magnesium - silicon alloy and aluminum - zinc - magnesium alloy, wherein the 5-series aluminum - magnesium alloy most widely used in the ship, then the 5-series marine aluminum What are the characteristics of it
5-series aluminum plate 5083,5086,5456 . 6-series alloy in seawater occur intergranular corrosion, and therefore use more upper part of the ship's structure, 7 alloy drawback is poor corrosion resistance, and therefore limited range. On the whole, the 5 Series marine aluminum sheet is the most widely used, the most promising of aluminum products.
5 Series 5083 aluminum can be seen as representative of marine aluminum products, the state has O, H111, H112, H116, H321, etc., 5083 aluminum alloy composition: Al Al: margin silicon Si: ≤0.40, copper Cu: ≤0.10, magnesium Mg: 4.0 ~ 4.9, zinc Zn: ≤0.25 Mn Mn: 0.40 ~ 1.0 titanium Ti: ≤0.15 chromium Cr: 0.05 ~ 0.25 iron Fe: 0 ~ 0.400,5083 aluminum moderate strength, corrosion resistance and good formability, anti- higher fatigue, generally used as the main hull structure. Others such as 5052,5086,5454,5456, also is used in the hull structure or pressure vessels, piping, hull and decks.
Generally, the thickness of the sheet is determined by the structure of the hull, vessel size and use of the site, etc., from the viewpoint of lightweight hull, generally try to use thin, but should also consider the depth of corrosion in the time sheet, usually used there are more than 1.6mm thin sheet of 30mm and above the slab. Press the shipyard also has a contract to use some special specifications sheet. Non-slip, using deck checkered.
From the perspective of the development of marine aluminum, at present, many domestic manufacturers have begun to focus on developing aluminum 5 Series, 6 Series marine aluminum, increased research efforts to expand the scale of production, aluminum and other high-end manufacturing to enter the marine market. Its 5083,5086,5454 and other aluminum in 2015 by the China Classification Society certification, in October passed the DNV certification, it has made foreign trade aluminum "World license."
With the promotion of innovation and R & D capacity, 5 Series marine aluminum plate will usher in greater development opportunities, provide a broad development space for aluminum transformation and upgrading.

solve the problem of aluminum alloy surface crack
Aluminum alloy flat ingot casting surface crack is a common defect.Aluminum alloy surface crack problems of semicontinuous casting process should consider many factors:
Mold taper;
Casting temperature '
Casting process slag
Melt Overheating;
Casting process too fast
cooling system
Alloy chemical composition
Skills
aluminum alloy 5052
Aluminum alloy flat ingot surface crack of solution:
The key to solve this problem to consider three main links:
Is the varieties of alloy chemical composition control
Varieties of casting process is alloy.
Is operation skills and natural conditions.
3003 h14 aluminum
The crystallization of aluminum alloy is also called the condensing tank, play a decisive role for casting.Aluminum alloy changes of taper of mould for casting can not be ignored.Taper of mould is too large flat ingot casting surface segregation tumors will increase, once the operation is not good will surface cracks, slag generated again when too narrow casting slab ingot mould can produce the surface cracking.A good teacher will adjust the size of the mould, casting to prevent flat bursts in the casting surface crack.
Aluminum alloy flat ingot surface crack for cooling water is very important.Cooling water is distributed evenly, bedding face and small surface strength, water size, water temperature are very big influence on solid-liquid region.
To sum up, the aluminum alloy flat ingot surface crack is made one of the common defects in the process of melting, eight analysis reason should be attention in the process of casting, will be the fault to ignore every detail, loss and waste.The control problem of alloy composition and impurities as well as the process setting need to be studied according to different environment analysis, make accurate judgment.For example: the surface of the aluminum alloy flat ingot slag smelting operation again in one of the most cause of surface crack.Majority is caused by improper operation, such as furnace temperature control - water - speed - flow disk horn mouth whether level off - crystallizer liquid surface height, there is every detail such as the operation.In order to prevent the happening of the aluminum alloy flat ingot surface crack phenomenon.From semi-continuous casting to the fully automatic casting, such as: automatic internal quality of casting defects is a new topic.For example: plume crystal column crystal. The vertical tree. Shining crystal column and prevention, such as we will continue to study and explore.
