Abstract
The utility model provides a graphite boat for sintering carbide blank, the boat is internal to be equipped with the pivot, and a plurality of carousel longitudinal arrangement are in the pivot. The utility model discloses a set up the carousel that can rotate in the graphite boat to the original sintering mode of stewing of developments sintering modal alteration. Owing of being heated between the pressed compact individuality that difference arouses on the one hand be favorable to avoiding owing to being burnt or mass defects such as burning, on the other hand is favorable to improving the interior gas flow efficiency of fritting furnace, promotes the interior sintering temperature evenly distributed of stove. So as to is under the prerequisite of guaranteeing the sintered product quality to great density sets up the pressed compact in the graphite boat, improve fritting furnace production efficiency.
Description
Technical field
This utility model relates to sintering cemented carbide device field, a kind of stone for sintered hard alloy blank
Mo Zhou.
Background technology
At present, hart metal product mass defect mainly shows as underburnt and burning.Research shows, sintering in-furnace temperature is not
Gas flows the unreasonable main cause being to cause drawbacks described above uniformly and at sintered article.
In existing sintering process, for improving sintering furnace production efficiency, it is intended to load more system to be sintered in graphite boat
Product, cause spacing between goods less, are unfavorable for that gas flows, thus temperature is difficult to be uniformly distributed, and causes product defects.
Utility model content
This utility model provides a kind of graphite boat for sintered hard alloy blank, to solve the problems referred to above.By
The rotating disk that can rotate is set in graphite boat, in the way of dynamic sinter pressed compact, changes original standing sintering processing.Initial bit
Put different pressed compacts under the drive of rotating disk, obtained identical sintering temperature, and the rotation of rotating disk is conducive to improving sintering
Furnace gases flowing towa taud efficiency, in promoting stove further, sintering temperature is uniformly distributed.On the premise of ensureing sintered article quality, energy
Enough pressed compact is set in graphite boat with greater density, improves sintering efficiency.
In order to realize the purpose of this utility model, plan employing techniques below:
A kind of graphite boat for sintered hard alloy blank, it is characterised in that be provided with rotating shaft in boat body, some rotating disks are indulged
To being arranged in described rotating shaft.
Further, described rotating disk is circular.
Further, graphite material selected by described rotating shaft and described rotating disk.
The beneficial effects of the utility model are:
1. pressed compact is followed rotating disk and is rotated, and to obtain uniform sintering temperature, thus avoids owing to being subject between pressed compact individuality
The mass defects such as the different underburnt caused of heat differential or burning.
2. turntable rotation is conducive to improving sintering furnace gas flow efficiency, and in promoting stove, sintering temperature is uniformly distributed, from
And on the premise of ensureing sintered article quality, pressed compact can be set in graphite boat with greater density, improve sintering furnace and produce
Efficiency.
Accompanying drawing explanation
Fig. 1 shows structural representation of the present utility model.
Fig. 2 shows the top view of this utility model rotating disk.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of graphite boat for sintered hard alloy blank, it is provided with rotating shaft 2 in boat body 1, some
Rotating disk 3 is longitudinally disposed in described rotating shaft 2.Described rotating shaft 2, by external actuating device 6 energy supply, is used for driving described rotating disk 3 to enter
Row rotates, and the pressed compact 4 that the most described rotating disk is arranged is heated evenly.
Described rotating disk 3 is circular.Be conducive to smooth rotation, and be easy to make.
Graphite material selected by described rotating shaft 2 and described rotating disk 3.It is easy to work under high temperature sintering environment.
This utility model detailed description of the invention is as follows:
Described rotating shaft 2 and described rotating disk 3 are assembled in described boat body 1, described pressed compact 4 is closely laid in described
On rotating disk 3, described boat body 1 is pushed in sintering furnace 5.
In sintering process, the rotation of described rotating disk 3 followed by the different described pressed compact 4 of initial position, is obtained identical
Sintering temperature.Meanwhile, gas stream in the stove, under described rotating disk 3 rotarily drives, circulates smooth and easy, equalizes the temperature of described pressed compact 4 further
Degree distribution, thus avoid described pressed compact 4 that underburnt or burning occur, improve sintered article quality.
