Description
Technical field
The invention belongs to metal material field, relate to a kind of foil and preparation method thereof for antitheft magnetic stripe being installed in vending articles.
Background technology
Antitheft magnetic stripe is widely used on books, audio-visual product and other extensive stocks, antitheft for commodity.So the requirement to magnetic stripe is: magnetic stripe material has good magnetic property, demagnetization and magnetizing repeatedly; And the thickness that requires magnetic stripe wants to be worked into very thin (at least will be worked into the thickness of 0.06mm), like this could be very hidden be loaded on commodity and be difficult for being found.Therefore, the material of magnetic stripe will be easy to processing, and it is high that material purity is wanted.If material is difficult for processing or purity is not high enough, not only affect the magnetic property of material, and the thickness (at least will be worked into the thickness of 0.06mm) that does not reach requirement just there will be defect.
Summary of the invention
The invention belongs to metal material field, relate to a kind of antitheft magnetic stripe foil and preparation method thereof in vending articles that is installed at.
Main purpose of the present invention is to provide a kind of have fine magnetic property and demagnetization and the magnetic foil that magnetizes repeatedly.
A kind ofly be installed in vending articles foil and preparation method thereof for antitheft magnetic stripe, it is characterized in that: the chemical composition mass percent of foil is:
C≤0.06%; Si≤0.50%; Mn≤1.0%; S≤0.005%; P≤0.03%; Cr≤1.5%; A1:2.0-4.0%; Ni:15-17%; Ti:0.5-1.5%, Fe surplus.
In order to meet the magnetic property of material, control wherein Ni:15-17%, Al:2.0-4.0%, Cr≤1.5%.In order to meet material, be easy to processing, control wherein C≤0.06%, P≤0.03%, and control Ti:0.5-1.5%, play the effect of crystal grain thinning.
A kind ofly be installed in vending articles foil and preparation method thereof for antitheft magnetic stripe, it is characterized in that: the preparation method of foil is:
(1) steel-making adopts two electroslag smelting techniques of just refine+single-phase electroslag remelting refining of three-phase electric slag furnace, guarantees the high cleanliness of material;
(2) steel rolling start rolling temperature is 1150-1200 ℃, and finishing temperature is 800-950 ℃, the direct hardening rolling after cooling of hot-rolled strip, and hot-rolled strip specification is (130-132) mm * 2.7mm; Hot-rolled strip rolling time pine a bit, while being convenient to solution treatment, coil internal/external heating even;
(3) hot-rolled strip is through 1030 ℃ of solution treatment, then pickling;
(4) through four-high mill, to be rolled down to thickness be 1.2mm to the hot-rolled strip after pickling, adopts 850 ℃ * 2m/min continuous annealing;
(5) through large six-high mill, rolling thickness is 0.25mm, adopts 800 ℃ * 2m/min continuous annealing;
(6) through too small six-high mill, being rolled down to thickness is 0.06mm;
In three-phase electric slag furnace smelting process, with technically pure iron, nickel plate, titanium sponge, the fine fodder that aluminium block etc. are pure is raw materials for metallurgy, guarantees low-phosphorous low silicon; Adopt high alkalinity slag, composition quality ratio is: CaO:CaF
2: Al
2o
3=2:1:1, can make sulphur content reach 0.002% level.
High cleanliness guarantees: two electroslag processes of three-phase electric slag furnace+single-phase esr, and starting material adopt with technically pure iron, nickel plate, titanium sponge, the high cleanliness raw materials such as aluminium block, technically pure iron surface, through processing of rust removing, is blown weak stirring of Ar and is got rid of nonmetal inclusion in employing bag after tapping; Esr adopts first refined solid slag, unstable oxide in slag as MnO, Fe
2o
3, SiO
2refining is removed, and then, with the solid slag refining liquid slag after refining, the liquid slag after refining is good is poured electroslag furnace into and carried out electroslag smelting.The solid slag of esr adopts composition quality per-cent to be: Al
2o
3account for 10-15%, CaF
2account for 85-90%, separately add CaO and account for 2-5%.The surface of steel ingot smooth (while testing other slag system, surface of steel ingot is rough) that this slag system is smelted.The steel ingot of smelting, through being mingled with grading at 1.5 grades, is mingled with size <10 μ m.
In the design mix of magnetic stripe foil material provided by the present invention, there is no precious metal element, therefore cost is more cheap; Material high purity, and be easy to shape.
Specific embodiment
In table 1, listed the embodiment in some productions of this invention material
In table 2, listed the Ingot Surface Quality situation that this material is used heterogeneity slag system when esr.
