Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Shown in Fig. 1 to 3, a kind of sintering furnace, comprising: the outer furnace shell 1 of side opening, the outer furnace shell 1 are equipped with vertical therewith
Hinged fire door 2 realizes that fire door 2 can be opened and closed relative to outer furnace shell 1, the cavity that the outer furnace shell 1 is constituted with fire door 2
Being equipped with outer profile in structure sidewards is cylindrical body and the liner 3 close to 2 side of fire door opening, and the liner 3 with cylindrical structure can
To be rotated relative to outer furnace shell 1, using the effect of this lateral rotation, can allow itself or idiosome shape and be easy because
Gravity and the object to drop uniformly rotates, when idiosome because gravity soon deform when, since the rotation of liner 3 can not
Disconnected change idiosome is affected by gravity a little, can give always idiosome due to gravity with effective solution by this change
One direction applies active force and leads to still that the idiosome of high-temperature shaping does not guarantee global shape well, and this utilizes rotation
The method for constantly changing the force position of gravity, also saves in conventional sintering furnace, since idiosome is static and and gravity original
Because leading to the idiosome hidden danger that just deformation occurs when not being formed also, product success rate is improved.It is opposite with 3 open-mouth of liner
Inner bottom wall be equipped with element fixing device 32, this element fixing device 32 can make in the prior art for green body it is special consolidate
