Abstract
The utility model relates to preparation of vacuum induction smelting of rare earth magnetic materials, in particular to a lever-type charging device used for a vacuum induction smelting furnace. The lever-type charging device is characterized in that a furnace cover hole seat, a vacuum sealing ring and an end cover are arranged on a furnace cover of the vacuum induction furnace and assembled to be used for performing the vacuum sealing on a guide rod; the guide rod is connected with a lever, a sliding groove, a fixing strut, a support fixing block through pin shafts to form the lever-type charging device; the sliding groove, the fixing strut and the support fixing block are arranged on the lever; and the lever-type charging device is fixed on the furnace cover of the vacuum induction smelting furnace through a bolt. When the lever is pried, rare earth element materials hung at the lower end of the guide rod enter a crucible randomly, stably and gradually, and are smelted stably together with smelted furnace charge, therefore splattering is reduced, safety hazards are eliminated, and the smelting loss of the furnace charge is reduced.
Description
Technical field
The utility model relates to the preparation of rareearth magnetic material vacuum induction melting, particularly a kind of lever feeding device that is used for vacuum induction melting furnace.
Background technology
Vacuum induction melting is the visual plant of melting rareearth magnetic material, and the metal charge that it utilizes the heating in medium frequency principle will place crucible produces under the action of alternating magnetic field at induction coil and melts, and the fusion furnace charge is poured mold into and is cooled to ingot casting and uses for subsequent handling.Rareearth magnetic material is by one or more of rare earth element nd, Pr, Ce, La, and it is formulated that Fe, B material are that main formula adds one or more of doped chemical Zr, Co, Nb, Al, Cu, Mo, and wherein rare earth element weight is at 22 ∽ 30wt%.The tradition smelting technology be with rare earth element, Fe, B and doped chemical by the formula rate melting in the crucible of packing in the lump because very easily oxidation of rare earth element, in fusion process reaction violent, promptly vacuum is 1 * 10 in induction furnace
-2When Pa charged into high-purity argon gas protection melting again, the furnace charge burn out rate was 1.2 ∽ 1.8wt%, and its main cause is that rare earth element material smelting time in crucible is long, excessively due to the electromagnetic agitation.For this reason, improved method is: the crucible of packing into of other furnace charge except that rare earth element carries out melting earlier, is fully putting into the melting of rare earth element material again after the melting.The feeding device of the vaccum sensitive stove that works online at present is design like this: establish a loading hopper in bell, with the freely falling body method rare earth element moment is fallen into crucible, carry out melting with the melting batch in the crucible, because the speed that falls down is fast, the reaction of rare earth element material is fierce, cause the fusion furnace charge to splash, there are potential safety hazard in the copper induction coil of easy burn-out, rubber cooling tube.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of lever feeding device that is used for vacuum induction melting furnace.It is that bell hole seat is set on the vaccum sensitive stove bell, vacuum seal hole seat, vaccum seal ring and end cap, they assemble up the vacuum seal that is used for guide rod, guide rod and lever with and on chute, fixing pole, the support fixation piece, link together by bearing pin and to constitute the lever feeding device, other is fixed by bolts on the vacuum induction melting furnace bell, at lower end of the guide rod 1 hole is arranged in addition, be used for hanging the rare earth element material of tying up through aluminium wire, move lever, lever is that fulcrum rotates with the bearing pin, by another bearing pin guide rod is moved down, the rare earth element material that hangs on it is slowly put into the fusion furnace charge, steadily carries out melting with the furnace charge of fusion.Therefore it can steadily add the rare earth element material in the crucible at random progressively, steadily carries out melting with the furnace charge of fusion, has reduced and has splashed, and eliminates safe hidden trouble, and reduces the furnace charge scaling loss.
Description of drawings
Fig. 1 is the lever feeding device structural representation of a kind of vacuum induction melting furnace described in the utility model.
Among the figure: lever-1, guide rod-2, bearing pin-3, chute-4, bearing pin-5, fixing pole-6, counterweight-7, carrying bolt-8, vacuum induction bell-9, locking nut-10, support fixation piece-11, bolt-12, vaccum seal ring-13, bell hole seat-14, vacuum seal ring seat-15, end cap-16, rare earth element material-17 is tied up aluminium wire-18, crucible-19, induction coil-20, fusion furnace charge-21.
The specific embodiment
The specific embodiment of the present utility model as shown in Figure 1.
Operating process is: guide rod 2 hangs through tying up rare earth element material 17 that aluminium wire 18 ties up to crucible 19, do not contact mutually, start intermediate frequency power supply, metal charge in the crucible 19 is after the fusing fully of induction coil 20 electromagnetic induction, inhour is moved the right-hand member of lever 1, lever 1 is that fulcrum rotates with bearing pin 5, by bearing pin 3 guide rod 2 is moved down, the rare earth element material 17 that hangs on it is slowly put into fusion furnace charge 21, steadily carry out melting together, reduced the alloy solution reaction and splashed, eliminated safe hidden trouble, the furnace charge burn out rate drops to 0.7 ∽ 0.9wt%.
Claims (3)
1. one kind is used for vacuum induction melting furnace lever feeding device, it is characterized in that: bell hole seat, vacuum seal hole seat, vaccum seal ring and end cap are set on the vaccum sensitive stove bell, they assemble up the vacuum seal that is used for guide rod, guide rod and lever with and on chute, fixedly pole, support fixation piece, linking together by bearing pin constitutes the lever feeding device, and other is fixed by bolts on the vacuum induction melting furnace bell.
