Description

A kind of magnesium alloy smelting refining agent that contains attapulgite
Technical field
The present invention relates to metal material processing technical field, relate in particular to a kind of magnesium alloy that contains attapulgite moltenRefining refining agent.
Background technology
Magnesium alloy is structural metallic materials the lightest in practical application, has high specific strength and specific stiffness, leadsThermal conductance electrically, electromagnetic wave shielding and the advantage such as Environmental compatibility is good, still there is the problem of poor corrosion resistance,Magnesium chemical property is active, often contains the impurity such as a large amount of oxides, carbide and sulfide, these in magnesium alloyImpurity significantly reduces mechanical property and the corrosion stability of magnesium alloy. Therefore, magnesium alloy uses molten at fusion process Chinese medicineAgent is carried out refining treatment to it, the object of refining treatment be to reduce sneak into impurity element in alloy as iron andNonmetal impurities is as magnesia etc.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, containing of a kind of degasification, slagging-off double effects is providedThe magnesium alloy smelting refining agent of attapulgite, can remove the non-metallic inclusion in magnesium alloy fused mass effectively,Can reduce again the loss of alloy rare earth elements, technique is simple, with low cost, metallurgical effect is good, to environment friendGood.
The present invention adopts following technical scheme to achieve these goals:
A magnesium alloy smelting refining agent that contains attapulgite, is made up of the raw material of following weight portion: concavo-convexThe native 8-10 part of rod, quartz sand nanometer powder 2-4 part, instrument comminuted steel shot 12-15 part, barium monoxide 3-4 part, oxygenChange boron 2-3 part, calcirm-fluoride 3-4 part, manganese chloride 1-2 part, magnesium sulfate 2-3 part, titanium sponge 0.3-0.5Part, nano silicon 2-3 part, stalk ashes 1-2 part, sodium nitrate 10-12 part, vermiculite power 1-2 part,Ice crystal 3-4 part, wooden carbon dust 5-7 part, carbon trichloride 13-15 part, rare earth chloride 7-9 part, zirconium chloride5-6 part, CaSi4-6 part.
Preferably, the described magnesium alloy smelting refining agent that contains attapulgite, by the raw material of following weight portionMake: 10 parts of attapulgites, 3 parts of quartz sand nanometer powders, 13 parts of instrument comminuted steel shots, 3 parts, barium monoxide, oxygenChange 3 parts of boron, 3 parts, calcirm-fluoride, 1 part of manganese chloride, 2 parts, magnesium sulfate, 0.5 part of titanium sponge, nanometer titanium dioxide2 parts of silicon, 2 parts, stalk ashes, 10 parts, sodium nitrate, 2 parts of vermiculite powers, 3.5 parts of ice crystals, wooden carbon dust 6Part, 15 parts of carbon trichlorides, 8 parts of rare earth chlorides, 5 parts of zirconium chlorides, CaSi5 part.
The preparation method of refining agent for the described magnesium alloy smelting that contains attapulgite, comprises following preparation stepRapid: the each raw material except titanium sponge and boron oxide to be mixed, be heated to molten condition, be then poured into pureQuench in water purification, then be ground into 100-200 order powder; Gained powder is added and is equivalent to powder weight 2-3%Silane resin acceptor kh-550, the sldium lauryl sulfate of 1-2%, after mixing, under 13-15MPa, suppressBecome base, then at 900-950 DEG C, calcine 3 hours, cooling after, then be ground into 150-250 order powder; ?After titanium sponge particle and boron oxide powder are evenly mixed with above-mentioned powder, pack.
Compared with the prior art, beneficial effect of the present invention is as follows:
Titanium sponge, manganese chloride and boron oxide isoreactivity composition in refining agent of the present invention can with melt inFerro element generation chemical reaction generates compound and slag making is discharged, and significantly reduces the content of ferro element in magnesium alloy,The ice crystal adding is conducive to improve the slaggability of solvent, adds zirconium chloride to be conducive to carry heavy alloyed being mingled withThe mechanical property of thing clearance and alloy and decay resistance, add CaSi and improve the energy that forms complex inclusionPower, can capture field trash sinking slag making rapidly effectively.
