Abstract
The invention relates to a rare-earth aluminum alloy aluminum ingot binding packaging tape and its making method, made by melting Al, Zn, Mg, Rare-earth, Ti, Zr, Cr, Mn, etc, it has cross section area 25-35 mm wide X1.0-1.5mm thick, tensile strength up to 350-400MPa, elongation up to 10-15%, adn good shock resistance, overcomes the defects in existing steel bands, does not corrode and change mechanical property for long time storage, has high strength, and can directly lift the whole bundle of aluminum ingots in a top-loading aluminum smelting furnace, improving working efficiency. It is smooth, no-burr, and unable to damage hands at the time of operation, etc.
Description
One, technical field:
The invention belongs to alloy melting heat treatment field, relate to a kind of rare earth aluminium alloy aluminium ingot bailing band and preparation method thereof specifically.
Two, background technology:
The present overwhelming majority of aluminium ingot bailing in the world adopts the galvanized steel strips (group III) in the GB4173-84 standard, its tensile strength 〉=490N/mm
2, percentage elongation ≮ %, sectional dimension is 25-40mm * 0.7-1.1mm, its production technology is cut into required width for the big width steel coil strip that will buy, aligns, is finished product around being rolled into through zinc-plated, shaping.But have following deficiency: (1) is though adopt steel band bundling intensity height, modulus of elasticity big, but, material viscosity little, poor toughness lower because of its stretch ratio, so under the situation of load that withstands shocks, (clash into steel band etc. from eminence overturning, sharp thing) as the aluminium ingot bundle, the steel band easy fracture, cause the bundle of loosing, bring greatly constant to transportation; (2) aluminium ingot bundle through repeatedly have bad luck and long-distance transport after arrive the user, steel band has produced permanent deformation, it is lower to tear bundle back second use rate open, can only handle as scrap steel; (3) when adopting large-scale top charging formula to melt the aluminium stove, the user wishes to put in order disposable hang in the stove of bundle aluminium ingot and need not tear strap open, but steel band pollutes aluminium liquid because of meeting, and can't put in order the stove of in bundling, the dress block-by-block adds aluminium ingot so must unpack, thereby influences smelting efficiency; (4) long-term storage or when transporting aluminium ingot at a distance, the perishable fracture of steel band causing the bundle of loosing, and makes troubles to transportation; (5) steel band is sheared for the monoblock band and is formed, and limit portion burr is more, when bundling is operated, easily scratches finger, scratches gloves; (6) steel coil strip weight is big, the carrying effort, and, be difficult for lengthy warehousing because of perishable.
Three, summary of the invention:
The present invention adopts a kind of rare earth aluminium alloy after melting and extrusion process and heat treatment and a kind of rare earth aluminium alloy aluminium ingot bailing band of making and preparation method thereof, to overcome the deficiency of above-mentioned galvanized steel strip.
The objective of the invention is to realize by following technical scheme:
A kind of rare earth aluminium alloy aluminium ingot bailing band and preparation method thereof, its characteristics are: it is that percentage by weight by following alloying element is mixed with:
Zinc content is: 5-9%, content of magnesium are: 0.5-2.0%, content of rare earth are: 0.05-0.2%, Ti content are: 0.1-0.2%, zirconium content are: 0.2-0.5%, chromium content are: 0.2-0.3%, manganese content are: the content of 0.1-0.4%, silicon and iron is respectively ≯ and 0.3%;
Method for making is as follows:
Zinc is added smelting furnace melting with 0.2-0.3%, manganese with 0.1-0.4% with 0.2-0.5%, chromium with 0.5-2.0%, zirconium with 5-9%, magnesium, the content of silicon and iron is respectively ≯ and 0.3%, and then add rare earth 0.05-0.2% and titanium 0.1-0.2% carries out grain refinement;
Percentage by weight proportioning by above-mentioned alloying element, carry out alloy melting with AOO level Raw Aluminium, after melting is qualified, passes through refining and leave standstill usefulness 100mm crystallizer, cast pole by hot top casting, after sawing, under 400-450 ℃ of temperature, carry out being extruded into strap with the aluminium extrusion press after the uniformization processing, after the processing of T6 artificial aging, promptly produce up-to-standard aluminum alloy strap.
Adopt rare earth aluminium alloy ingot bailing band of the present invention and preparation method thereof, can produce width 25-35mm, thickness is high strength alumin ium alloy aluminium ingot bailing band in the rare earth of 1.0-1.5mm, intensity reaches 350-400MPa, stretch ratio reaches 10-15%, strength-to-density ratio reaches 130-150 (steel band is 60), according to the bundling mode of steel band, satisfies the bailing condition of conventional aluminium ingot fully; Under the condition of bearing same impact load, aluminum alloy strip is because viscosity is big, the toughness height, the impact of bearing than steel band often, with the aluminium ingot of alloy band bailing, by long-distance transport, repeatedly handling is not found broken belt, distortion, the bundle of loosing phenomenon.The aluminum alloy strip resistance to corrosion is strong, long period transportation, deposit, the burn into mechanical characteristics is not constant, and is specious, because the extrusion dies design time leaves fillet, so the smooth burr free of alloy belt edge is not hindered hand during operation, do not scratch gloves; In the whole bundle of roof-mounted large-scale smelting furnace hoisting process, the alloy band has shown its preceence, and the dress of can not unpacking will be put in order the bundle aluminium ingot and hang in the stove, improve work efficiency greatly; Because of the high-load of alloying element is 2%, and alloy band weight accounts for the minimum ratio of whole bundle aluminium ingot weight, so that alloying element influences secondary remelting body composition is very little, can ignore.
Four, the specific embodiment:
Embodiment:
A kind of rare earth aluminium alloy aluminium ingot bailing band and preparation method thereof, its characteristics are: it is that percentage by weight by following alloying element is mixed with:
Zinc content is: 5-9%, content of magnesium are: 0.5-2.0%, content of rare earth are: 0.05-0.2%, Ti content are: 0.1-0.2%, zirconium content are: 0.2-0.5%, chromium content are: 0.2-0.3%, manganese content are: the content of 0.1-0.4%, silicon and iron is respectively ≯ and 0.3%;
Method for making is as follows:
