The invention relates to a method for preparing a vehicle oil delivery pipe alloy material which comprises the following ingredients in percentage by weight: 0.3-0.5% of manganese, 1-1.2% of iron, 0.5-1% of magnesium, 0.5-1% of zinc, 5-8% of copper, 0.2-0.5% of nickel, 0.03-0.05% of zirconium, 0.01-0.03% of cobalt, 0.001-0.003% of rear earth which contains yttrium and dysprosium and the balance of aluminium.
Description
Technical field
The invention belongs to metal material field, refer to especially a kind of automobile-used transition pipeline alloy material preparation method.
Background technology
At present, automobile-used transition pipeline alloy material is mainly iron alloy or copper alloy, but because iron alloy pipe gentle not high, and use copper pipe cost also higher, and the ratio of copper is great, increases the overall weight of vehicle.
Aluminium proportion low, come instead of copper or iron to make automobile-used transition pipeline with aluminium alloy and have lot of advantages.But existing aluminium alloy is when finally being processed into the tubing of thin-walled, because the ductility of aluminium alloy is lower and occur easily breaking or leakage phenomenon than copper, and the Corrosion Protection of existing aluminum alloy materials is crossed less than requiring.
Summary of the invention
The purpose of this invention is to provide a kind of automobile-used transition pipeline alloy material, the ductility of described aluminium alloy is higher than existing aluminium alloy, and proportion is lower than copper, and can keep enough intensity, and Corrosion Protection is higher.
The present invention is achieved by the following technical solutions:
A kind of automobile-used transition pipeline alloy material preparation method:
The composition of aluminium alloy includes by weight percentage, the zirconium of the copper of the magnesium of the manganese of 0.3-0.5%, the iron of 1-1.2%, 0.5-1%, the zinc of 0.5-1%, 5-8%, the nickel of 0.2-0.5%, 0.03-0.05%, the cobalt of 0.01-0.03%, the rare earth that contains yttrium and dysprosium of 0.001-0.003% and the aluminium of surplus are prepared material;
Be smelted into after aluminium after calculating, zinc, magnesium, copper, cobalt alumel, mangal and ferro-aluminium mixed and add successively zirconium alloy, rare earth aluminium alloy behind the liquid and then carry out casting and rolling after the refining.
Described smelting temperature is 850 ± 20 ℃; Refining temperature is 850-870 ℃, and refining time is 1-2 hour; Then holding temperature is cast at 800-820 ℃, and constant temperature is cooled to 500 ± 20 ℃ and is rolled, and keeps the constant temperature cooling in the operation of rolling, final roll forming.
The cooling rate of described constant temperature cooling remains on 2.5-3 ℃/minute.
Wherein aluminium, zinc, copper and magnesium are selected high purity aluminium ingot, zinc ingot metal, copper ingot and magnesium ingot.
The weight ratio of described yttrium and dysprosium is 2: 1.
Described manganese, zirconium, iron, cobalt, nickel, rare earth join in the aluminium alloy with manganese aluminium, titanium aluminium, zirconium aluminium, iron aluminium, cobalt nickel aluminium, rare earth aluminium alloy mode respectively.
The beneficial effect that the present invention compares with prior art is:
The aluminium alloy pipe of manufacturing of the present invention also has height when having same intensity and lifts ductility, and corrosion resistance nature is higher; Cost is far below copper pipe, and the gap of performance and copper pipe is not much better than iron pipe very much.
