Abstract
A kind of zirconium pipe saggar for molten steel Determining oxygen probe, including：The fixed plate being made up of aluminum oxide, offers the multiple through holes passed through for zirconium pipe in the fixed plate；The potassium alms bowl body of upper end open, forms on the potassium alms bowl body madial wall for supporting the step at the edge of the fixed plate, and the bottom notch of the potassium alms bowl body forms in the vertical direction and the through hole multiple recesses correspondingly.During with the zirconium pipe saggar sintering zirconium pipe, inclination of the zirconium pipe during moving can be prevented, therefore with the arranging density of enlarged relative zirconium pipe, and then the efficiency of sintering can be improved, reduce the amount of the alumina powder entered in zirconium pipe simultaneously as far as possible, therefore also improve the quality of zirconium pipe.
Description
Technical field
The utility model is related to Determining oxygen probe manufacture field, and in particular to a kind of zirconium pipe casket for molten steel Determining oxygen probe
Alms bowl.
Background technology
Determining oxygen probe is the special equipment for detecting the oxygen content of molten steel in stove, and its core is by adulterating by one
The zirconium pipe that zirconium oxide is made, its consistency need to be maintained at 97% or so.Its preparation process is substantially：Prepared by ceramic size, injection
Shaping, low temperature de-waxing, high temperature sintering.Its sintering when typically be inserted directly in potassium alms bowl stack alumina powder jointed in.But
This method causes which to be susceptible to incline when moving, and then difficult in operation behind in alumina powder jointed entrance zirconium pipe
To remove completely, certainty of measurement is therefore affected；In addition, also limit sintered zirconium pipe quantity in each potassium alms bowl, burning is reduced
Junction efficiency.
Utility model content
For solving the above problems, the utility model provides a kind of efficiency high, product quality and is used on molten steel Determining oxygen probe
Zirconium pipe saggar.
A kind of zirconium pipe saggar that the utility model is provided, including：
The fixed plate being made up of aluminum oxide, offers the multiple through holes passed through for zirconium pipe in the fixed plate；
The potassium alms bowl body of upper end open, forms on the potassium alms bowl body madial wall for supporting the platform at the edge of the fixed plate
Rank, the bottom notch of the potassium alms bowl body form in the vertical direction and the through hole multiple recesses correspondingly.
Preferably, the through hole is uniformly distributed along vertical and horizontal in the fixed plate.
Description of the drawings
Fig. 1 is the exploded perspective view of the zirconium pipe saggar and zirconium pipe of a preferred embodiment；
Fig. 2 is the sectional view of the zirconium pipe saggar and zirconium pipe of a preferred embodiment.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing.In the utility model
Description in, " " center ", " on ", D score, "left", "right", " vertical ", " level ", " interior ", " outward " it should be noted that term
Deng instruction orientation or position relationship be based on orientation shown in the drawings or position relationship, be for only for ease of description this practicality newly
Type is described with simplifying, rather than is indicated or implied that the device or element of indication must be with specific orientation, with specific orientation
Construction and operation, therefore it is not intended that to restriction of the present utility model.Additionally, term " first ", " second ", " the 3rd " are only used
In description purpose, and it is not intended that indicating or hint relative importance.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", " being connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected, or be detachably connected, or integratedly
Connection；Can be mechanically connected, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning of the language in the utility model.
Please refer to Fig. 1 to Fig. 2.The zirconium pipe saggar that the utility model is provided, including：
The fixed plate 2 being made up of aluminum oxide, offers the multiple through holes 20 passed through for zirconium pipe 3 in fixed plate 2；Upper end open
Potassium alms bowl body 1, form the step 10 at the edge for supporting and fixing plate 2, the bottom of potassium alms bowl body 1 on 1 madial wall of potassium alms bowl body
Portion is recessed to form in the vertical direction and through hole 20 multiple recesses 13 correspondingly.
Alumina powder is loaded onto in saggar body to certain altitude, covers fixed plate, then by zirconium pipe one by one from through hole
In be inserted in alumina powder body, and the upper end of zirconium pipe is exposed above fixed plate.So it is prevented that zirconium pipe is being moved
During inclination, therefore with the arranging density of enlarged relative zirconium pipe, and then can improve the efficiency of sintering, while subtract as far as possible
The amount of the alumina powder for entering in zirconium pipe less, therefore also improves the quality of zirconium pipe.
Preferably, in some embodiments other, through hole 20 is uniformly distributed along vertical and horizontal in fixed plate 2.This
Sample, can be easy to count.
In the utility model, other non-detailed portions belong to prior art, therefore will not be described here.
Finally it should be noted that：Various embodiments above is only in order to illustrating the technical solution of the utility model, rather than which is limited
System；Although being described in detail to the utility model with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：Which still can be modified to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from this practicality new
The scope of each embodiment technical scheme of type.
