Description

A kind of preparation method of Al-Ti-B alloy fining agent
Technical field
The invention belongs to metallurgical smelting field, more particularly to a kind of preparation method of Al-Ti-B alloy fining agent.
Background technology
The evolution of Ti, B grain graining agent experienced three phases:Titanium-boron additive, Al-Ti-B intermediate alloy top, aluminium Titanium boron wire, wherein titanium boron wire grain refiner are a kind of blocky additives, and Ti, B grain graining agent is with its outstanding thinning effect It may compare favourably with import titanium boron wire, be much better than aluminium titanium intermediate alloy, for most of aluminium alloy, actually economic suitable crystalline substance Grain fining agent.
Ti, B grain graining agent is made casting obtain tiny equiax crystal, is eliminated feather due to its excellent thinning effect Brilliant and column crystal provides the institutional framework of good inherence for later processing, can improve casting efficiently against casting crack Part appearance.
In the preparation method of Ti, B grain graining agent, it is divided into conventional ceramic technique, villiaumite method, pure titanium particle method etc., mesh by raw material Before, most extensive and effective method is villiaumite method, i.e., produces aluminium titanium by thermit reaction using potassium fluotitanate and potassium fluoborate Boron alloy, its thinning effect of the Al-Ti-B alloy of the method production is strong and sufficiently stable, the drawback is that due in alloying process Corruption of the metallic compound impurity and fused salt that the by-product fluoaluminic acid sylvite of middle generation and reaction are brought into refractory material Lose the field trash brought into, it is difficult to the effective thoroughly removal from Al-Ti-B alloy, cause these impurity brought into fining agent by In the middle of the alloy of refinement, aluminium alloy thinning effect, while the presence of low melting point salt impurity are reduced.
In the patent of invention of 102031403 A of Patent No. CN, it is noted that a kind of refined high cleanliness Al-Ti-B alloy Manufacturing method includes the following steps:1) aluminium ingot is melted and adds in potassium fluotitanate and potassium fluoborate alloying;2) it pours out and floats on aluminium The byproduct of reaction on liquid surface, and neutralized with alumina powder;3) temperature of aluminum liquid is promoted, sprinkles aluminium oxide bisque;4) with the logical argon of pipe Gas or nitrogen make the residue liquid emersion wrapped up in molten aluminum, and are neutralized;5) after rotating refinery by de-gassing technical finesse using minute bubbles Measure its hydrogen content;6) under 800 DEG C or more of Warm status, special high-temp antioxidizing covering oxidant layer is sprinkled;7) molten aluminum will be promoted Temperature, the filter box equipped with aluminium oxide ceramics filter is imported by molten aluminum, and on-line filtration processing is carried out to alloy molten aluminum;8) most After reduce temperature of aluminum liquid, exclude scum silica frost, cast molding is produced into aluminium titanium boron wire.This method can efficiently separate out Al-Ti-B alloy Fluoride salt and other field trashes in liquid so that impurity is reduced in Al-Ti-B alloy fining agent, cleanliness factor increases substantially;It is lacked Point is that discharging volume is low, and being added after degasification due to special high-temp antioxidizing covering oxidant layer, and golden liquid is in previous step In will be aoxidized or be sucked gas so that material occur stomata or it is loose the phenomenon that, reduce the elongation percentage of material.
For above-mentioned phenomenon, 104561619 B of patent CN disclose a kind of preparation side of aluminium titanium boron wire grain refiner Method, the aluminium titanium boron wire grain refiner by the way of continuous casting and rolling, are as follows after the melting:(1) it melts:By fine aluminium Ingot, which adds in, to be fused into molten aluminum in crucible furnace and heats;(2) alloying:Into step (1) during molten aluminum heating into molten aluminum Dispensing is added in, potassium chloride, potassium fluoborate and potassium fluotitanate is followed successively by, alloy molten aluminum is obtained after heating stirring reaction completely;(3) it stirs Mix degassing slagging-off:Alloy molten aluminum obtained in step (2) is transferred to stirring degassing in line frequency coreless electric holding furnace;(4) casting connects It rolls:Molten aluminum after slagging-off in step (3) is transmitted in mold, is filtered successively through flow-conveying groove, crystallizing wheel cavity and tandem mill Take-up obtains aluminium titanium boron wire after tandem rolling;The preparation method of the invention aluminium titanium boron wire grain refiner, avoids molten aluminum from being aoxidized or inhaled Enter gas and occur stomata or it is loose the phenomenon that, improve the elongation percentage of aluminium titanium boron wire;Its shortcoming is what is generated in reaction process A large amount of liquid slags have fabulous wetability with aluminium, to remove totally, extremely difficult.
Therefore, research and development are a kind of can improve the elongation percentage of Al-Ti-B alloy, and greatly improve Al-Ti-B alloy cleanliness factor The preparation method of Al-Ti-B alloy fining agent is necessary.
Invention content
The elongation percentage of Al-Ti-B alloy can be improved, and greatly improve the technical problem to be solved in the present invention is to provide a kind of The preparation method of the Al-Ti-B alloy fining agent of Al-Ti-B alloy cleanliness factor.
In order to solve the above technical problems, the technical scheme is that:A kind of preparation method of Al-Ti-B alloy fining agent, Its innovative point is:The preparation method includes the following steps:
(1) it melts:99.95% fine aluminium ingot is added in and is fused into molten aluminum in crucible furnace and heats, heats 2-4 hours, makes Temperature of aluminum liquid reaches 760-860 DEG C;
