Abstract
The invention discloses a preparation method of a refining agent for scrap aluminum smelting. The refining agent is prepared from the following raw materials in parts by weight: 4-5 parts of silicon powder, 6-8 parts of potash feldspar, 3-5 parts of dolomite, 8-10 parts of Na2TiF6, 3-5 parts of NaF, 5-8 parts of aluminium chloride, 4-5 parts of nano silicon dioxide, 10-12 parts of clay, 3-4 parts of sodium fluosilicate, 4-5 parts of sodium nitrate, 2-3 parts of titanium white, 6-8 parts of fluorite, 3-4 parts of bowlder powder and 1-2 parts of smectite. When being used for casting production, the high-grade scrap aluminum alloy solution obtained by treating with the refining agent obviously enhances the yield, especially lowers the porosity in the casting by 1-2 degrees so as to effectively control the porosity and not to generate pores on the casting surface, obviously lowers the oxide inclusions by 1 level, and obviously enhances the mechanical properties of the casting. The refining agent enhances the strength and hardness of the scrap aluminum alloy, and is beneficial to enhancing the comprehensive properties of the scrap aluminum alloy.
Description
Technical field
The present invention relates to a kind of Way of Remelting Scrap Aluminium field, belong to Way of Remelting Scrap Aluminium refining agent.
Background technology
In aluminium alloy smelting process, need to use insulating covering agent, slagging agent, slag-cleaning agent, refining agent etc., aluminium scrap adds refining agent when temperature reaches 720 degree left and right, the refining agent using in traditional aluminium scrap manufacturing processed, can cause the degree of porosity of finished product higher, at cast(ing) surface, how can produce pore, the ratio of oxidation foreign material is also higher, has affected the performance of aluminium casting.
Summary of the invention
The object of this invention is to provide a kind of Way of Remelting Scrap Aluminium refining agent preparation method, improve the over-all properties of aluminium.
The technical solution used in the present invention is as follows:
A Way of Remelting Scrap Aluminium refining agent preparation method, is made by the raw material of following weight part: silica flour 4-5, potassium felspar sand 6-8, rhombspar 3-5, Na
2tiF
68-10, NaF 3-5, aluminum chloride 5-8, nano silicon 4-5, clay 10-12, Sodium Silicofluoride 3-4, SODIUMNITRATE 4-5, titanium dioxide 2-3, fluorite 6-8, jade powder 3-4, montmorillonite 1-2; Preparation method mixes each raw material, is heated to molten state and stirs remove slag, and then, is poured into Quench in pure water, then is ground into 100-200 order powder; Gained powder is added and is equivalent to the silane resin acceptor kh-550 of powder weight 2-3%, the nanometer aluminium powder of 1-2%, after mixing, under 8-15Mpa, be pressed into base, then, at 900-950 ℃, calcine 3-4 hour, cooling after, be ground into again 150-250 order powder, obtain.
The present invention processes through above-mentioned refining agent, obtain high-quality scrap aluminium alloy liquation, such molten aluminium alloy is for Foundry Production, the degree of porosity obviously improving in yield rate, particularly foundry goods reduces 1-2 degree, is controlled effectively, can not produce pore at cast(ing) surface, trapped oxide also obviously reduces, and oxide inclusion is 1 grade of left and right, and the mechanical property of foundry goods obviously improves.The intensity and the hardness that have increased scrap aluminium alloy, be conducive to improve scrap aluminium alloy over-all properties.
Embodiment
Below in conjunction with executing example, the invention will be further described, but be not limited to the following example.
A Way of Remelting Scrap Aluminium refining agent preparation method, includes following operation steps: by following weight (kilogram) raw material makes: silica flour 4, potassium felspar sand 6, rhombspar 5, Na
