Abstract
The invention provides an aluminum alloy which is used for meridian tyre mold of vehicles; the alloy contains the elements of aluminum, zinc, magnesium, titanium, copper and zirconium; the weight percent of every component is that 0.09 percent of silicon, 0.28 percent of manganese, 1.82 percent of magnesium, 5.83 percent of zinc, 0.005 percent of copper, 0.03 percent of titanium, 0.03 percent of zirconium and the rest is aluminum; the alloy is provided with good liquidity and strong stamping capability and good dynamic property; in this way, the alloy can meet the functional requirements of the meridian tyre mold of vehicles in a proper way.
Description
Technical field
The present invention relates to a kind of aluminium alloy, especially, relate to a kind of aluminium alloy for Vehicular radial ply tyre moulds.
Background technology
Vehicular radial ply tyre moulds uses aluminium alloy usually, usually use such as the AL-Si alloy of the trade mark at present as AC4D, the castability of this alloy is better, but owing to the Si composition is controlled reason improperly, its intensity difference, easy to wear and easily in the sulfidation of making tire, spillover takes place, the cleaning surface of mould is worn easily and pit occurs, thereby influences tire quality.Another kind of commonly used aluminium alloy is to be the AL-Mg alloy of AC7A such as the trade mark, and the intensity of this alloy is higher, yet because Mg composition ratio is improper, it is mobile poor, and it is bigger to cast difficulty, causes the casting flaw of mould easily, thereby influences the quality of tire.
Summary of the invention
The object of the present invention is to provide a kind of aluminium alloy for Vehicular radial ply tyre moulds, the Si in this alloy, Mg composition ratio are appropriate, make this alloy have good mobility, stronger cavity filling ability and mechanical property preferably.
In order to solve the technical problem, the weight percent of the composition of aluminium alloy provided by the invention is: silicon accounts for 0.09%, and manganese accounts for 0.28%, and magnesium accounts for 1.82%, and zinc accounts for 5.83%, and copper accounts for 0.005%, and titanium accounts for 0.03%, and zirconium accounts for 0.03%, and all the other are aluminium.
The performance of alloy of the present invention and described alloy commonly used is according to showing:
In last table, σ
bRefer to the maximum stress value that alloy is reached when rupturing in drawing process, σ from beginning to taking place
0.2Produce 0.2% o'clock the stress that the permanent afterflow of alloy equals raw footage; Refer to that hence one can see that, at normal temperatures, aluminium alloy of the present invention is the alloy phase ratio of AC4D with the trade mark, yield strength and offset yield strength all significantly improve, with the trade mark is that the aluminium alloy of AC7A is compared, and the difference of yield strength is very little, and offset yield strength is significantly increased; At high temperature, the yield strength of aluminium alloy of the present invention and offset yield strength have significant raising than existing alloy; Be that aluminium alloy provided by the invention has good mobility and stronger cavity filling ability, and possess mechanical property preferably, can satisfy the performance requriements of Vehicular radial ply tyre moulds preferably.
Embodiment
The weight percent of the composition of aluminium alloy provided by the invention is: silicon accounts for 0.09%, and manganese accounts for 0.28%, and magnesium accounts for 1.82%, and zinc accounts for 5.83%, and copper accounts for 0.005%, and titanium accounts for 0.03%, and zirconium accounts for 0.03%, and all the other are aluminium.
The preparation process of aluminium alloy of the present invention can be with reference to following steps:
Step 1, melting is prepared, and promptly clears up the burner hearth and the furnace wall of process furnace, and crucible is inserted in the process furnace; Cleaning crucible and all the other standby gears are as casting ladle, bell jar, draw together slag wooden dipper, thermopair, riser pipe, mould ingot etc.; Crucible is heated to 100 ℃ to 200 ℃, and stenciling coating, standby gear is heated to 100 ℃ to 200 ℃, it should be noted that, when stenciling coating, the coating of brushing on crucible and standby gear should be uniform and smooth, and described coating should be known for one of ordinary skill in the art, such as can be the mixture of talcum part and water glass; With standby gear with the drying and preheating of stove through 250 ℃;
Step 2, melting, promptly account for 0.09% according to silicon, manganese accounts for 0.28%, and magnesium accounts for 1.82%, zinc accounts for 5.83%, copper accounts for 0.005%, titanium 0.03%, zirconium 0.03%, impurity ratio wherein is less than 0.1, and all the other take by weighing fine aluminium, pure zinc and aluminium silicon and aluminum bronze master alloy as furnace charge for the weight percent of aluminium; Furnace charge is put into crucible, add insulating covering agent, change into aluminium water to furnace charge, described insulating covering agent can be the mixture of Repone K and magnesium chloride; Add magnesium ingot, be heated to fusing, add titanium and zirconium again, be heated to fusing; Continuing heating is between 680 ℃ to 740 ℃ up to temperature of aluminum liquid, carries out refining with degasifier, slag-cleaning agent; Allow static about 15 minutes of alloy solution, sampling put into and survey the gas model, check in this solution whether also have bubble, if any bubble or gas slag, continuation adding degasifier, slag-cleaning agent carry out concise, do not have bubble in solution; Continue the heating crucible, be adjusted to 700 ℃ to 710 ℃ to solution temperature, and keep this temperature; Enter step 3;
Step 3, casting, promptly adopt persons skilled in the art casting step as can be known, but it should be noted that the core temperature should be more than 80 ℃, and core should be placed on the casting center, with the error of central position ± 1 millimeter scope, all piece together the edge joint position asbestos compacting of case, and sandbox is fixed on the median septum, rises the liquid time between 50 seconds to 150 seconds, keep-up pressure between 0.6 to 0.8 normal atmosphere, and the time that keeps this pressure was at 15 minutes to 50 minutes.
Step 4, thermal treatment, promptly foundry goods is carried out surface-conditioning after, be placed in the baking oven, oven temperature is adjusted to 300 ℃, be incubated after 4 hours, cold to stove, finish preparation to alloy-steel casting.
Below in conjunction with the trade mark is the result of use that the alloy of AC4D and AC7A illustrates alloy provided by the present invention:
The composition of alloy of the present invention and alloy commonly used is according to table
The performance of alloy of the present invention and alloy commonly used is according to table
As can be known from the above table, at normal temperatures, aluminium alloy of the present invention is the alloy phase ratio of AC4D with the trade mark, yield strength and offset yield strength all significantly improve, with the trade mark is that the aluminium alloy of AC7A is compared, and the difference of yield strength is very little, and offset yield strength is significantly increased; At high temperature, the yield strength of aluminium alloy of the present invention and offset yield strength have significant raising than existing alloy; Be that aluminium alloy provided by the invention has good mobility and stronger cavity filling ability, and possess mechanical property preferably, can satisfy the performance requriements of Vehicular radial ply tyre moulds preferably.
