Abstract
The present invention relates to metal material. Al-Sr intermediate alloy is manufactured through the steps of: mixing industrial pure strontium carbonate, aluminium oxide, potassium borofluoride and potassium chloride in a certain proportion, putting the material on the surface of molten aluminium, powering the molten aluminium with DC current for 20-60 min and final casting molten aluminium in metal mold or casting and rolling into string. The intermediate alloy has excellent Al-Si alloy modifying effect.
Description
The invention belongs to metal material field, particularly a kind of preparation method who is used for the rotten aluminium-strontium master alloy of aluminum-silicon alloy.
Generally adopt " mixing method " preparation aluminium-strontium master alloy at present both at home and abroad, for example the disclosed method for preparing aluminium-strontium master alloy of 99 years the 1st phase 33-35 of " light metal " magazine page or leaf is exactly to adopt " mixing method " earlier, this method is earlier fine aluminium to be melted, be warming up to 900 ℃, Preparation of Metallic Strontium is added in the aluminium liquid then, after treating the strontium fusion, cast makes aluminium-strontium master alloy.There is following shortcoming in this method: the strontium oxidation is serious, and loss is big, and utilization ratio is wayward; Reaction is violent, and environmental pollution is serious; Master alloy is organized thick, the modification effect instability; Metal is difficult for preserving stores transportation difficulty etc.
The objective of the invention is to overcome the shortcoming that above-mentioned existing preparation method exists, utilize metal heredity principle to develop a kind of preparation method of new aluminium-strontium master alloy.
The present invention realizes in the following manner:
A kind of method for preparing aluminium-strontium master alloy is characterized in that comprising the steps:
1), with industrial pure carbon acid Strontium, technical pure aluminum fluoride, technical pure potassium fluoborate, technical pure Repone K uniform mixing, the weight percent of each component is:
Tan Suan Strontium aluminum fluoride potassium fluoborate Repone K
10-30％ 20-40％ 20-30％ 20-30％
2), aluminium liquid fusing is warming up to 760 ℃-960 ℃, more above-mentioned industrial purification compound is placed aluminium liquid surface;
3), feed galvanic current in aluminium liquid, cathode current density is 0.5-6A/cm
2
4), be 20 minutes-60 minutes conduction time, then aluminium liquid poured into metal mold or continuous casting and rolling becomes the silk thread shape.
Aluminium-strontium the master alloy that utilizes this method to produce, Al
4Sr phase length dimension is in the 10-50um scope, and the modification effect to aluminum-silicon alloy under the identical condition of consumption doubles, and its modification effect has hereditary effect, so be referred to as heredity aluminium-strontium master alloy.
Provide a most preferred embodiment of the present invention below:
1) industrial pure material is mixed by following composition and proportioning:
Tan Suan Strontium aluminum fluoride potassium fluoborate Repone K
30％ 25％ 20％ 25％
2) aluminium liquid is warming up to 760 ℃, and above-mentioned industrial pure material is placed aluminium liquid surface;
3) feed galvanic current in aluminium liquid, cathode current density is 2A/cm
2
4) energising is after 30 minutes, and it is the silk thread of 9.5mm that the continuous casting and rolling of aluminium liquid is become diameter.
The thread master alloy diameter that utilizes this method to produce is 9.5mm, and wherein as-cast structure is mainly by Al
4Sr constitutes, Al
4Sr length is 5-20um.In aluminium (8-13) % silicon alloy, add aluminium-strontium master alloy of 0.05-0.1%, under the metal mold condition, can make modification effect reach 5-6 level (is best modification effect by national standard).
