Abstract
The utility model discloses a door plant of graphite box, including the door plant main part, the door plant main part install the both ends at the graphite box, the door plant main part on evenly be provided with a plurality of through -holes, the diameter of through -hole reduce gradually to the centre by the inside and outside side of door plant main part, form the loudspeaker form. The utility model discloses an interior outer aperture is poor can to improve the gaseous velocity of flow that gets into the graphite box, thereby change to the mode of admitting air in the graphite box, solve among the product sintering process volatile gaseous clean problem of can not discharging.
Description
Technical field
This utility model relates to two end-plates (abbreviation door-plate) of a kind of graphite casing, the specially door-plate of graphite casing in powder metallurgy product vacuum sintering furnace.
Background technology
Powder metallurgy product for reaching higher quality, needs to install the graphite casing of a 450mm*450mm*1000mm in sintering process in vacuum drying oven.Product is placed in graphite boxes body, be filled with nitrogen in stove during sintering, hydrogen gas plays carrier function, enters graphite casing through graphite casing top air inlet and mixes with product volatilization gas and nitrogen, hydrogen discharged out of the furnace together with product volatilization gas impurity by graphite casing base bleed hole by vacuum pump.Due to the intake method problem of graphite casing, the volatilization gas of product can not effectively discharge out of the furnace, have impact on product quality.
Utility model content
The purpose of this utility model is to provide for a kind of door-plate with through hole, solves the problems referred to above of prior art.
This utility model patent can be realized by below scheme:
The door-plate of a kind of graphite casing, including door-plate main body, described door-plate main body is arranged on the two ends of graphite casing；Being evenly arranged with some through holes in described door-plate main body, the diameter of described through hole is gradually reduced towards centre by the medial and lateral of door-plate main body, is formed horn-like.
It is horn-like that described through hole is centrosymmetric.
Described through hole is at a diameter of 2.5mm of the inside and outside two sides of door-plate main body, and centre is the most carefully located as 1.5mm.
5 exhausting holes that are of five storeys, spacing 80mm is bored in described door-plate main body.
This utility model can improve gas by inside and outside aperture difference and enter the flow velocity of graphite casing；Thus change the mode of air inlet in graphite boxes body, solve volatilization gas in product sintering process and can not discharge clean problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 be Figure 1A-A to cross-sectional view；
In figure, 1, door-plate main body 2, through hole.
Detailed description of the invention
Of the present utility model structural representation is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
The door-plate of a kind of graphite casing as depicted in figs. 1 and 2, including door-plate main body 1, described door-plate main body 1 is arranged on the two ends of graphite casing；Being evenly arranged with some through holes 2 in described door-plate main body 1, the diameter of described through hole 2 is gradually reduced towards centre by the medial and lateral of door-plate main body 1, is formed horn-like.
It is horn-like that described through hole 2 is centrosymmetric.
Described through hole 2 is at a diameter of 2.5mm of the inside and outside two sides of door-plate main body, and centre is the most carefully located as 1.5mm.
5 exhausting holes that are of five storeys, spacing 80mm is bored in described door-plate main body.
Claims (4)
