Abstract
The utility model relates to a vacuum smelting furnace device for producing ingots by smelting neodymium, iron and boron, which comprises two vacuum smelting furnaces which are respectively connected with a vacuum pump through pipes; a connecting pipe is arranged between the two vacuum pumps to connect the two vacuum pumps, and pipes entering the vacuum smelting furnaces are respectively provided with control valves. Though the technical proposal, the utility model connects two vacuum pumps together so as to use the two vacuum pumps to vacuumize one vacuum smelting furnace, thereby greatly improving the production efficiency.
Description
Technical field
The utility model relates to the vacuum melting furnace apparatus that is used for neodymium iron boron melting system ingot.
Background technology
Nd-Fe-Bo permanent magnet material is the permanent-magnet material based on intermetallic compound Nd2Fe14B.Neodymium iron boron has high magnetic energy product and strong power, simultaneously the advantage of high-energy-density.Nd-Fe-Bo permanent magnet material has obtained extensive use in modern industry and electronic technology, make miniaturization, lightweight, the slimming of equipment such as instrument and meter, electroacoustic motor, magnetic separation magnetization.Powder metallurgical technique is adopted in existing Nd-Fe-Bo permanent magnet material manufacturing, and technological process is as follows: batching → melting system ingot → powder process → die mould → sintering tempering → magnetic detection → mill processing → pin is cut processing → plating → finished product.Above-mentioned melting system ingot process generally adopts vacuum induction melting furnace, and a vacuum induction melting furnace connects a vavuum pump respectively, but because existing vavuum pump power problem, a smelting furnace vacuumizes and needs 30 minutes, and production efficiency is low.
Summary of the invention
Vacuumize inefficient technical problem in order to solve above-mentioned vacuum induction melting furnace, the purpose of this utility model provides a kind of vacuum melting furnace apparatus that is used for neodymium iron boron melting system ingot, and it has characteristics simple in structure, that production efficiency is high.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
The vacuum melting furnace apparatus that is used for neodymium iron boron melting system ingot, wrap two vacuum melting furnaces, two vacuum melting furnaces are connected with vavuum pump by pipeline respectively, be provided with the pipeline that tube connector connects two vavuum pumps between described two vavuum pumps, and be provided with by-pass valve control entering on the pipeline of vacuum melting furnace respectively.
The utility model links together two vavuum pumps by above-mentioned technical scheme, can use two vavuum pumps to a vacuum melting stove evacuation, has improved the efficient of producing greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
The vacuum melting furnace that is used for neodymium iron boron melting system ingot 1 device as shown in Figure 1, wrap two vacuum melting furnaces 1, two vacuum melting furnaces 1 are connected with vavuum pump 2 by pipeline 5 respectively, be provided with tube connector 3 between described two vavuum pumps 2 and connect the pipeline 5 of two vavuum pumps 2, and on the pipeline 5 that enters vacuum melting furnace 1, be provided with by-pass valve control 4 respectively.
In the time of work, closed by-pass valve control 4 vacuumizes with 2 pairs of vacuum melting furnaces 1 of two vavuum pumps earlier, waits to vacuumize and finishes, and after this vacuum melting furnace 1 work, vacuumizes with 2 pairs of other vacuum melting furnaces 1 of two vavuum pumps again.
