Abstract
The utility model relates to a vacuum smelter hearth which can produce neodymiumferrumboron rare earth permanent magnetic alloy materials and rare earth hydrogen reserving alloy materials. The utility model is characterized in that a rotatable cooling roller with a level axes is arranged under a middle bag in a hearth body, the cooling roller is internally provided with an inner cavity which is filled with a flowing cooling medium; a turntable which rotates vertically along the axes is arranged below the cooling roller, the turntable is internally provided with an inner cavity which is filled with the flowing cooling medium. The utility model aims at solving the problems of uneven alloy ingredients of products after the process of production of alloy materials and maladaptation of requirements on large scale production.
Description
The utility model relates to a kind of vacuum melting furnace of producing permanent-magnet rare-earth NdFeB alloy material and rare earth hydrogen storage alloy material.
The vacuum melting furnace of present employed production permanent-magnet rare-earth NdFeB alloy material and rare earth hydrogen storage alloy material is work like this: under vacuum or protective atmosphere; with alloy melting; then with the alloy liquation of fusing to going in the die cavity that has a cooling medium to cool off, cast the alloy spindle.There is the shortcoming of following two aspects in this method:
1, alloying component inequality influences the uniformity of alloy, and in addition, this kind method also needs spindle is carried out fragmentation.
2, the large batch of production requirement of this method incompatibility.
At problem set forth above, the utility model provides a kind of vacuum smelting fast solidification stove, and its purpose is to solve the alloying component inequality of coming out in the process of producing alloy material, needs through broken process the problem that aspects such as the large batch of production requirement of incompatibility exist.
The utility model comes to be realized by the following technical programs:
A kind of vacuum smelting fast solidification stove, it includes vacuum system feeder, vacuum furnace shell, crucible and tundish etc., it is characterized in that: under the tundish in body of heater, an axis horizontal, rotating chill roll are set, this chill roll inside is provided with inner chamber, and inner chamber is connected with cooling medium flowing; The axle of chill roll is being provided with dynamic sealing device by the furnace shell place: be provided with the vertically rotating disk of rotation of an axis below chill roll, the single-ended support of the rotating shaft of this rotating disk is provided with dynamic sealing device in rotating shaft by the furnace shell place; The inside of this rotating disk is provided with inner chamber, is connected with cooling medium flowing in the chamber.
Chill roll can be replaced by two chill roll arranged side by side.
In tundish, be provided with heater.
But the diameter of roller is 200mm---the scope of 1200mm.
Vertically the rotating disk of rotation can tilt 0～60 °.
Cooling medium is cooling water, fluorine Lyons, liquid nitrogen.
Advantage of the present utility model and effect:
By technical scheme provided by the utility model; can solve the existing problem of smelting furnace in the past well; its main design is a kind of at vacuum environment (or under protective atmosphere); make metal and alloy material fusing with frequency induction heating; and liquation is cast on the chill roll of rotation; liquation is cooled off rapidly, crystallize into thin slice, continue cooling on the rotating disk below thin slice drops to.Vacuum smelting fast solidification stove provided by the utility model is specially adapted to the melting of the metal material and the alloy of easy oxidation, is specially adapted to the melting of high-performance Ne-Fe-B RE permanent magnetic alloy.Compare with the conventional vacuum smelting furnace, the crystal property of material is good, easily pulverizes, and has save the coarse crushing operation of material, can directly enter powder-grinding process.
Accompanying drawing 1 is a structural representation of the present utility model; Accompanying drawing 2 is the structural representation of furnace shell 6.
The utility model is specifically described by embodiment below in conjunction with accompanying drawing:
In accompanying drawing 1 as can be seen, the below of the tundish 4 (or funnel) in body of heater, be provided with a chill roll 5, the axis direction of this chill roll 5 is for being horizontally disposed with, one section the diameter of chill roll 5 below tundish 4 is bigger than the place, two ends, can improve cooling effect like this, make crystallization effect better.The inside of chill roll 5 is a cavity, and the both ends open of chill roll 5, the cooling medium of circulation ceaselessly flow.Below chill roll 5, be provided with rotating disk 7.The inside of this rotating disk 7 also is provided with inner chamber, and inner chamber is connected with cooling medium flowing.The axle two end supports of chill roll 5 also can support by an end, but has at least the axle of an end to connect with the transmission mechanism of body of heater outside, and chill roll 5 rotates under the drive of transmission mechanism.
The utility model also has another kind of technical scheme, that is: chill roll 5 can be replaced by two chill rolls 5 arranged side by side, and the gap between two chill rolls 5 is just relative with the hole of tundish 4 of their tops.The alloy liquation flows out from the elongated hole of tundish 4, through the gap between the chill roll 5, forms alloy sheet, drops on the rotating disk 7.
In tundish 4, be provided with heater, its objective is the alloy liquation in flow process, avoid the cooling, influence crystallization effect.
