Abstract
The utility model relates to a cooling device of a sintered neodymium iron boron vacuum smelting furnace, belonging to the field of machines. The traditional vacuum smelting furnace adopts a common self-cooling circulating water cooling method. Since the cooling speed is slow, the yield is caused to be low and high-performance products are very difficult to produce. The cooling device comprises a water pump I, a water tank I, and a furnace body with a cooling passage I, wherein the water pump I is connected with one end of the cooling passage I through a water pipe, the water tank I is connected with the water pump I through a water pipe, and the other end of the cooling passage I is connected with the water tank I through a water pipe. The cooling device further comprises a water pump II, a water tank II and a refrigerator. The furnace body is provided with a cooling passage II. One end of the cooling passage II is connected with the water pump II through a water pipe. The water tank II is connected with the water pump II through a water pipe. The refrigerator is connected with the water tank II through a water pipe. The other end of the cooling passage II is connected with the refrigerator through a water pipe. By adopting the structure, the cooling device of the sintered neodymium iron boron vacuum smelting furnace has the advantages that the overall cooling speed is accelerated, and the production efficiency and the product performance are improved.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of cooling device of sintered NdFeB vacuum melting furnace.
Background technology
In the sintered NdFeB production procedure, must use vacuum melting furnace (containing vacuum rejection tablet stove) various raw material are melted and become alloy, make rejection tablet or ingot casting, this needs the high temperature of 1300～1500 ℃, and rejection tablet or ingot casting are through after high melt, need to be cooled to rapidly below 50 ℃, cool time is shorter, and the organization of rejection tablet or ingot casting is better, and the properties of product of producing are just better, therefore, some products are had relatively high expectations to the cooling effect of vacuum melting furnace cooling system.What traditional vacuum melting furnace adopted is common self cooling circulating water mode, this mode is because the water temperature cooling velocity is slower, and need 3～5 hours cool time, causes that the output of 3～4 stoves is only arranged every day, and under the restriction of cooling velocity, also be difficult to the high performance product of output.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of quickening cooling velocity, thereby improves the cooling device of the sintered NdFeB vacuum melting furnace of product yield and quality.
the purpose of this utility model can realize by following technical proposal: a kind of cooling device of sintered NdFeB vacuum melting furnace, comprise water pump one and water tank one and the body of heater with cooling duct one, described water pump one is connected with an end of cooling duct one by water pipe, described water tank one is connected with water pump one by water pipe, the other end of described cooling duct one is connected with water tank one by water pipe, it is characterized in that, described cooling device also comprises water pump two, water tank two and refrigeration machine, described body of heater is provided with cooling duct two, one end of cooling duct two is connected with water pump two by water pipe, described water tank two is connected with water pump two by water pipe, described refrigeration machine is connected with water tank two by water pipe, the other end of described cooling duct two is connected with refrigeration machine by water pipe.after adopting said structure, vacuum melting furnace has possessed two cover cooling systems, and mutually noninterfere, can be by the needs of cooling velocity, divide two parts cooling to vacuum melting furnace: aqueous cold plate, blower fan, copper the critical component that the temperature cooling velocity is had relatively high expectations such as rolls and connects that cover cooling system with refrigeration machine, all the other conventional positions connect common cooling system, like this, under the refrigeration machine effect, interior minimum the reaching below 0 ℃ of water temperature of water tank two that connects refrigeration machine, guaranteed the cooling effect rapidly of vacuum melting furnace key position, thereby accelerated whole cooling velocity, make the production efficiency in every stove/sky by 3～4 stoves, bring up to 6～8 stoves, and can the high performance product of output.
In the cooling device of above-mentioned a kind of sintered NdFeB vacuum melting furnace, it is characterized in that, be provided with valve between an end of described cooling duct two and water pump two, valve is fixedly mounted on an end and the connecting water pipe between water pump two of cooling duct.Control by valve flow and the flow velocity that cooling fluid enters cooling duct two, thereby arbitrarily control the cooling velocity of vacuum melting furnace.
In the cooling device of above-mentioned a kind of sintered NdFeB vacuum melting furnace, it is characterized in that, described refrigeration machine is compression refrigerating machine.The compression refrigerating machine refrigerating speed is fast, and refrigeration is good.
Compared with prior art, the utility model can divide two parts to carry out to vacuum melting furnace simultaneously cooling, thereby accelerate whole cooling velocity after adopting said structure, enhances productivity and properties of product.
