Abstract
A vacuum sintering furnace comprises a furnace body and a heating chamber arranged inside the furnace body, which is characterized in that the heating chamber is provided with a closed shell and a heat-preservation layer, and a door is arranged at the end part of the heating chamber, and a stirring fan is arranged on the upper part of the heating chamber. The heating chamber inside the vacuum sintering furnace is designed to be a closed structure and is provided with a fan forcing the flow of the air, thereby realizing the counter-flowing heating when in heating; therefore, the heating speed of the utility model is enhanced; meanwhile, for the furnace realizes the heating with air to enhance the uniformity of the heating temperature, the sintered quality of the rare-earth permanent-magnetic material is improved. In addition, adopting the utility model, the vacuum unit can be stopped working in the heat-preservation process, thereby reducing the energy consumption and prolonging the service life of the vacuum unit.
Description
The utility model is a kind of agglomerating plant, is a kind of vacuum sintering furnace that is used in the sintering process of rare earth permanent-magnetic material specifically.
What originally the vacuum sintering furnace that uses during the rare earth material sintering adopted is open heating clamber, and does not force the device of gas flow in heating clamber.The vacuum sintering furnace of said structure can only heat under vacuum state, and in the heating process heat scatter and disappear bigger, so firing rate is slow, if take with the gas heating then do not guarantee the uniformity of temperature.
The purpose of this utility model provides a kind of vacuum sintering furnace of new structure, and it can overcome existing shortcoming in the prior art, the temperature homogeneity in the time of can improving firing rate and guarantee work.
The purpose of this utility model is achieved in that it comprises body of heater and is installed in the interior heating clamber of body of heater, is characterized in that heating clamber is provided with enclosed housing, and be provided with heat-insulation layer that door is established in the end, is provided with agitation fan on the top of heating clamber.
The utility model is made enclosed construction with the heating clamber in the vacuum sintering furnace, and be provided with the agitation fan that forced gas flows, when heating, can realize Convective Heating, so firing rate of the present utility model is improved, and improved the uniformity coefficient of heating-up temperature owing to realized the heating of band gas simultaneously, the sintering quality of rare earth permanent-magnetic material is improved.In addition, the utility model can just make the vacuum unit quit work in insulating process, so can cut down the consumption of energy, provide the service life of vacuum unit.
The utility model is described in more detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is a fragmentary sectional elevation view of the present utility model.
Fig. 2 is the side view of Fig. 1.
By accompanying drawing as seen, the 3rd, body of heater, i.e. vacuum chamber, the ring flange 5 of its side is connected with vacuum system.Be provided with heating clamber in body of heater, be provided with enclosed housing 7 around the heating clamber, and be provided with heat-insulation layer 4 in housing, the two ends of heating clamber are provided with door.The agitation fan 8 that motor 1 drives is installed on the top of heating clamber.One side of heating clamber is provided with cooling fan 9.On body of heater, also be provided with inflation inlet 2, be used for when sintering furnace is worked, charging into inert gas.Body of heater is provided with water-cooling system 6.
