Abstract
The utility model discloses a graphite heating body specially used for baking an induction furnace. The graphite heating body comprises a first graphite heating block and a second graphite heating block which are matched with the inner wall of a crucible and are formed into a one-piece structure, wherein the first graphite heating block is arranged on the second graphite heating block; the first graphite heating block is a circular platform, the vertical section of which is of a trapezoidal structure; the second graphite heating block is a circular platform, the vertical section of which is of an inverted trapezoidal structure; and the bottom face of the first graphite heating block is completely overlapped with the top face of the second graphite heating block. The graphite bar heating body specially used for baking the induction furnace is consistent with the inner shape of the crucible, so that the crucible and ramming materials are allowed to be sintered into an integrated body fully and uniformly, and the smelting can be guaranteed to be performed safely.
Description
Technical field
When the utility model relates to the induction furnace baker, use the heater technical field, refer to particularly a kind of use for laboratory 10kg induction furnace baking special graphite calandria.
Background technology
Vaccum sensitive stove will drop into normal use, must the crucible after the block stove be toasted, in order to make, builds material and crucible by laying bricks or stones and can be combined into fully an integral body.Baker heater used was graphite block in bulk in the past, though can toast, owing to can't placing evenly, caused the ramming mass sintering inhomogeneous unreal with the fire door sintering, caused induction furnace in smelting process, to have the risk that bleed-out occurs because of erosion.
The utility model content
The purpose of this utility model will provide a kind of induction furnace baking special graphite calandria exactly, and this graphite rod can match with the crucible interior shape, thereby reaches the purpose of even baker, and the abundant sintering of fire door ramming mass.
For realizing this purpose, the induction furnace baking special graphite calandria that the utility model is designed, it is characterized in that: it comprises the first graphite heating piece and the second graphite heating piece of the integral structure be complementary with the crucible inwall, wherein, described the first graphite heating piece is positioned at the top of the second graphite heating piece, described the first graphite heating piece is that vertical cross section is trapezoidal round platform, described the second graphite heating piece is that vertical cross section is the round platform of inverted trapezoidal, and the bottom surface of described the first graphite heating piece overlaps fully with the end face of the second graphite heating piece.
Further, the altitude range of described the first graphite heating piece is 6 ~ 8cm, and the altitude range of described the second graphite heating piece is 22 ~ 24cm.
Further, the diameter of described the first graphite heating piece end face is 4 ~ 6cm, and the diameter of described the first graphite heating piece bottom surface is 11cm, and the diameter of described the second graphite heating piece bottom surface is 8 ~ 10cm.
Further, the density range of described the first graphite heating piece and the second graphite heating piece is 1.4 ~ 1.6g/cm
3.
Further, the sidewall of described the first graphite heating piece middle part offers through hole.
The special oven graphite rod heater of the utility model design matches with the interior shape of crucible, has guaranteed that crucible and ramming mass can evenly be sintered to one fully, thereby has guaranteed that the safety of smelting carries out.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Wherein, the 1-the first graphite heating piece, the 2-the second graphite heating piece, 3-through hole.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The induction furnace baking special graphite calandria of the utility model design, as depicted in figs. 1 and 2, it comprises the first graphite heating piece 1 and the second graphite heating piece 2 of the integral structure be complementary with the crucible inwall, wherein, the first graphite heating piece 1 is positioned at the top of the second graphite heating piece 2, the first graphite heating piece 1 is that vertical cross section is trapezoidal round platform, the second graphite heating piece 2 is that vertical cross section is the round platform of inverted trapezoidal, and the bottom surface of the first graphite heating piece 1 overlaps fully with the end face of the second graphite heating piece 2.
In technique scheme, the altitude range of the first graphite heating piece 1 is 6 ~ 8cm, and the altitude range of the second graphite heating piece 2 is 22 ~ 24cm.The diameter of the first graphite heating piece 1 end face is 4 ~ 6cm, and the diameter of the first graphite heating piece 1 bottom surface is 11cm, and the diameter of the second graphite heating piece 2 bottom surfaces is 8 ~ 10cm.
In technique scheme, the density range of the first graphite heating piece 1 and the second graphite heating piece 2 is 1.4 ~ 1.6g/cm
3.The graphite rod material of the first graphite heating piece 1 and the second graphite heating piece 2 is the extruded anisotropic graphite class.
In technique scheme, the sidewall of the first graphite heating piece 1 middle part offers through hole 3.This through hole 3, for the clamping of fixture to graphite heating body, has facilitated placement and the extraction of graphite rod.
Compare traditional graphite block in bulk, integral type graphite heating body of the present utility model can better fit with the inwall of crucible, guaranteed that crucible and ramming mass can evenly be sintered to one fully, the bleed-out phenomenon occurred because of erosion of having avoided that induction furnace deposits in smelting process.
When the utility model is used: after stove puzzles, graphite heating body of the present utility model is put into to crucible, should note making temperature evenly increase during the graphite heating body intensification, must not add suddenly high-powerly, temperature is raise suddenly; The moisture of being convenient to crucible that keeps during beginning slowly heating up fully excludes, when temperature reaches 1500
0After C, rise to rapidly 1800
0C, in order to form a hard closely knit surperficial sinter layer; After power failure, rotate and promote graphite core, treat that temperature is down to 1100
0During C, take out graphite core.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
