The production system is composed of a batching machine, a V-shaped mixer, a magnesite brick smelting furnace, a vacuum induction smelting furnace and a centrifugal casting machine, wherein the batching machine is controlled by a computer for batching automatically; in production, vanadium and aluminum are subjected to automatic batching in proportion by the batching machine and then are mixed by the V-shaped mixer, the mixed vanadium-aluminum alloy raw material is put into the magnesite brick smelting furnace for smelting, the smelted vanadium-aluminum alloy is subjected to cooling treatment and then is put into the vacuum induction smelting furnace for smelting, and the smelted vanadium-aluminum alloy is put into the centrifugal casting machine for casting. The production system of the aircraft-grade vanadium-aluminum alloy has the beneficial effects that the impurity content in the alloy is low, the degree of purity is high, the alloy component is uniform and compact, and the degree of uniformity of the prepared vanadium-aluminum alloy is up to 99.5%, thereby satisfying the requirement of preparation of aviation titanium alloys.
Description
Technical field
The utility model relates to a kind of production system of vananum, particularly a kind of production system of aviation-grade vananum.
Background technology
The binary master alloy that vananum is made up of v element and aluminium element is mainly used in the preparation of titanium alloy.And titanium alloy is widely used in space flight and aviation industry, chemistry and preparation equipment industry, oceanographic equipment and sports equipment manufacturing, biomedical equipment process industry, automobile industry, naval vessel production, war industry and daily necessities production.
At present, the production system of the domestic vananum that generally adopts is to build pyrotic smelting stove and bonnet by laying bricks or stones with graphite cake, then with powdery Vanadium Pentoxide in FLAKES and aluminium powder according to a certain ratio with in the Reaktionsofen of packing into after the artificial mixed; Igniting is smelted then; Naturally cooling was come out of the stove in 24 hours; Sull is removed in manual sorting; Crushing packing.There are two big mass defects in the vananum that this production system is produced, and the one, foreign matter content is high, and wherein the content of C reaches 0.051%, and the content of Fe and Si reaches more than 0.2%; The 2nd, homogeneity of ingredients is poor, and each position segregation of alloy pig is bigger, and the deviation of different sites reaches 3%.Therefore be difficult to reach the requirement of aviation-grade titanium alloy preparation.
Summary of the invention
The technical problem that the utility model will solve is problem and the production system of a kind of aviation-grade vananum of providing of vananum impurity height and lack of homogeneity of the production system output of existing vananum.
The described production system of the utility model is made up of proportioning machine, V-arrangement mixer, magnesia brick smelting furnace, vacuum induction melting furnace and centrifugal casting machine; Wherein proportioning machine is prepared burden by computer control automatically; Vanadium aluminium is undertaken being mixed by the V-arrangement mixer behind the automatic blending by proportioning machine earlier in proportion during production; Put into smelting in the magnesia brick smelting furnace to the vananum raw material that mixes; Carry out melting in the vacuum induction melting furnace putting into after the good vananum processing under cooling of smelting, in centrifugal casting machine, cast the vananum after the melting.
Connect by rail between proportioning machine, V-arrangement mixer, magnesia brick smelting furnace, vacuum induction melting furnace are adjacent with centrifugal casting machine; Being convenient to vananum utilizes rail car to transport in producing process; Save manpower and PT, greatly improved the efficient of smelting.
The production process of the utility model is described below:
(1), is built into the magnesia brick smelting furnace with magnesia brick;
(2), the magnesia brick smelting furnace that puzzles is placed in liquefied gas or the coal gas dry kiln dry 12 hours;
(3), adopt computer-controlled proportioning machine to prepare burden, by weight the proportioning of vananum be: V58%-Al42%, V65%-Al35%, V75%-Al25%;
(4), pack into V-type mixer thorough mixing 15 minutes of the raw material that proportioning is good, then mixed raw materials is packed in the magnesia brick smelting furnace, light the furnace charge that installs with magnesium chips and smelt, smelting temperature is 1800-2700 ℃, 1 minute tap to tap time;
(5), handle after good alloy pig naturally cools to 30-40 ℃, destroy the oxide debris on surface smelting;
(6), the alloy block of handling well put into vacuum induction melting furnace carry out melting, smelting temperature is 1600-1700 ℃, alloy melting to liquid state;
(7), will melt good alloy casts in centrifugal casting machine;
(8), under vacuum state, adopt argon gas circulation cooling 5 hours, come out of the stove after making the temperature of alloy pig drop to below 200 ℃;
(9), crushing packing.
The beneficial effect of the utility model: alloy impurity is low; Purity is high; Composition is even, fine and close; The vananum foreign matter content that adopts the described production system of the utility model to be produced through actual detected reduces than the vananum foreign matter content that adopts existing production system to produce greatly, and wherein C content is 0.003%, has descended 17 times; Si content 0.10% has reduced by 50%; Fe content 0.15% has reduced by 25%; The vananum uniformity coefficient of being produced reaches 99.5%; The needs of aero titanium alloy preparation have been satisfied.
