Abstract
The invention discloses a manufacturing process of an AlZr10 intermediate alloy, which particularly comprises the following steps: preheating a crucible furnace or line frequency furnace, then adding an Al99.70 aluminum ingot for remelting into the furnace, heating to melt the aluminum ingot, then adding potassium fluozirconate, and stirring; after the reaction is completed, pouring out scum floating on the surface of the molten aluminum, and then spreading a rice husk ash covering on the surface of the molten aluminum; inserting a rotary degassing machine into a melting bath in the crucible furnace or line frequency furnace, introducing high-purity argon gas for refining, and refining; and pouring out scum on the surface of the molten aluminum again until the rice husk ash covering and the scum are cleaned up, heating the molten aluminum to 950-1050 DEG C again, and casting to obtain an aluminum-zirconium intermediate alloy finished waffle ingot product of which the zirconium content is 9-11%. An Al3Zr metal compound in the aluminum-zirconium intermediate alloy produced by the invention is uniformly and dispersely distributed; and the invention provides a refining method combining rotary degassing and rice husk ash covering to solve the problem of non-metallic inclusions in the finished product.
Description
Technical field
The present invention relates to aluminium alloy manufacture field, refer more particularly to a kind of manufacture craft of AlZr10 master alloy.
Background technology
In aluminium, add recrystallization temperature, creep strength and the resistance toheat that micro-zirconium can improve aluminium.In aluminium alloy (as 7XXX is associated gold) add appropriate zirconium, due to Al
3the precipitation effect of Zr particle, it is refinement alloy grain obviously, puies forward heavy alloyed hot strength, increases stress corrosion dehiscence resistant ability and anti-fatigue performance, improves alloy comprehensive mechanical performance.Generally at 7XXX, be associated zirconium addition in gold and be generally 0.1～0.15%.Employing adds the aluminium zirconium hardener of metal zirconium explained hereafter in aluminium liquid, due to aluminium liquid in fusion process at high temperature for a long time, cause alloy aluminum liquid seriously overheated, in ingot structure, easily form the Al of a large amount of bulks
3the gathering agglomerate of Zr compound and chemical combination thereof, reduces the effect of zirconium, and finished product alloy is caused to detrimentally affect.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point of the prior art and provide a kind of production technique simple, effectively isolate after alloy reaction remaining fluoride salt and other inclusion in aluminium alloy, improve the manufacture craft of AlZr10 master alloy of the performance of this master alloy.
The present invention realizes in the following way:
A manufacture craft for AlZr10 master alloy, is characterized in that: specific as follows: after crucible oven or main frequency furnace preheating, add aluminium ingot the fusing that heats up for Al99.70 remelting in stove, keep melt temperature 750-850 ℃; Then add potassium fluozirconate, and stir, make it to occur following reaction: K
2zrF
6+ Al → Al
3zr+mKF+nAlF
3;
Question response is complete, pours out the scum silica frost that floats over aluminium liquid surface, then on liquid aluminum, sprinkles one deck rice husk ash coverture; In crucible oven or main frequency furnace, in molten bath, insert rotary degassing machine, pass into high-purity argon gas refining 10 minutes for refining;
Again pour out the scum silica frost of liquid level, rice husk ash coverture and scum silica frost are all cleaned out; Rice husk ash plays special absorption, cohesive action to the liquid potassium fluoroaluminate disperseing in cleaning aluminium liquid;
Again temperature of aluminum liquid is risen to 950-1050 ℃, being cast into zirconium content is the finished product China husband ingot of the aluminium zirconium hardener of 9-11%.
The invention has the advantages that: adopt aluminium ingot and potassium fluozirconate raw material production containing the aluminium zirconium hardener of zirconium 9-11%; Al in the aluminium zirconium hardener that the present invention produces
3zr metallic compound, it is evenly distributed, disperse; The present invention, for solving the problem of non-metallic inclusion in finished product, proposes the method for refining that rotation degasification adds rice husk ash coverture.
Embodiment
The specific embodiment of the invention is described in detail in detail:
A manufacture craft for AlZr10 master alloy, specific as follows: after crucible oven or main frequency furnace preheating, in stove, to add aluminium ingot the fusing that heats up for Al99.70 remelting, keep melt temperature 750-850 ℃; Because the volume of potassium fluozirconate is larger, for convenience of stirring operation, divide and add potassium fluozirconate 2-3 time, and stir, make it to occur following reaction: K
2zrF
6+ Al → Al
3zr+mKF+nAlF
3; Question response is complete, pours out the scum silica frost that floats over aluminium liquid surface, then on liquid aluminum, sprinkles one deck rice husk ash coverture; In crucible oven or main frequency furnace, in molten bath, insert rotary degassing machine, pass into high-purity argon gas refining 10 minutes for refining; Again pour out the scum silica frost of liquid level, rice husk ash coverture and scum silica frost are all cleaned out; Rice husk ash plays special absorption, cohesive action to the liquid potassium fluoroaluminate disperseing in cleaning aluminium liquid; Again temperature of aluminum liquid is risen to 950-1050 ℃, being cast into zirconium content is the finished product China husband ingot of the aluminium zirconium hardener of 9-11%.
