Abstract
The utility model relates to a loading container for detecting high-temperature performance of ironstone, in particular to a graphite crucible for detecting restoring soft-melting performance of the ironstone. The utility model mainly solves the technical problem that the existing crucible can not satisfy the requirements of detection of soft-melting performance of the ironstone. The graphite crucible device comprises a graphite crucible body and a lower bottom support pipe, and is characterized in that one to two circles of ventilation holes are distributed on the bottom of the graphite crucible body along the direction of a circle with intervals; the shapes of the inarching position of the graphite crucible body and the lower bottom support pipe are matched; and the upper part of the crucible is provided with an external threaded head. The utility model is mainly used for detection of restoring soft-melting performance of the ironstone.
Description
Technical field
The utility model relates to a kind of iron ore high-temperature behavior and detects used charge cask, is a kind of graphite crucible that is used for reduction of iron ore soft heat Performance Detection specifically.
Background technology
Reduction of iron ore soft heat Performance Detection is to detect the high-temperature behavior of iron ore, comprising: a series of hot properties parameters such as softening temperature, fusion temperature, drippage temperature.This detection needs the process of analog blast furnace ironmaking, concrete testing process is: (generally require 10～12.5mm) a certain amount of detected ores to pack in the crucible designated size, the bottom of stock column and top layer are with addition of a certain amount of coke, crucible is put into the molten drop stove, the crucible bottom is connected with the trustship of going to the bottom, and top connects goes up the pipe connection.In testing process, need continuously to feed the CO for preparing and N2 gaseous mixture as reducing agent, will test sample be required heating gradually according to detecting by the heater of molten drop stove simultaneously, until ore the reduction soft heat takes place and drip from crucible bottom.Because the drippage temperature of iron ore generally all is in the scope between 1450～1500 ℃, so belonging to high temperature, this detection detects, the ore of fusion can be bonded on the crucible, once just needs to change a crucible so detect.
By foregoing description as can be known, the crucible that is used to detect need satisfy following requirement:
1. high temperature resistant, refractoriness is not less than 2000 ℃;
2. can satisfy test enters ore reduction from crucible bottom with reducibility gas;
3. the liquid slag iron of the reducing and smelting of ore generation can drip smoothly in time;
4. by deadweight and the passive trustship sealing of going to the bottom, guarantee enough inner reducibility gas amounts that enters.
5. crucible is changed simple and convenient.
Chinese patent 200420089726.9 discloses " graphite crucible with cover ", and is used when belonging to the growing technology field and being used for the Bridgman-Stockbarge method for growing crystal.Being characterized as of this utility model: with carbon-free graphite rod processing, be made up of crucible cover and crucible two parts, become the cylinder pyramidal structure, aperture is arranged at crucible top.The 26S Proteasome Structure and Function of this crucible can not satisfy the front and describe the requirement of ore soft heat Performance Detection with crucible.
The utility model content
The purpose of this utility model just provides a kind of graphite crucible device, and requirement can be satisfied the requirement of iron ore soft heat Performance Detection, that is: high temperature resistant, can ventilate from the bottom, liquid slag iron can drip smoothly, can be by the effective sealing of deadweight realization with the trustship of going to the bottom, processing is simple, and cost is low.
The purpose of this utility model specifically is achieved in that
A kind of graphite crucible device that is applied to reduction of iron ore soft heat Performance Detection comprises the graphite crucible body and the trustship two parts of going to the bottom.The bottom of graphite crucible body along the circumferential direction is furnished with 1-2 week passage at interval, and the graphite crucible body and the trustship of going to the bottom are abutted against place's shape and are complementary, and crucible top is the external connection screw head.
Wherein, crucible bottom is that circular cone adds the truncated cone-shaped structure, and the trustship of going to the bottom is cylindric, and the upper end is the sealing frustum cone structure with the crucible bottom mating.
The utility model can produce following beneficial effect:
1 passage can guarantee to detect with reducing gas and feed in the crucible from the bottom, also plays the channeling that oozes of liquid slag iron simultaneously;
2. the polycrystalline substance of taper makes tested ore when drippage takes place, and liquid slag iron can in time drip smoothly, avoids taking place the drop deposition of crucible bottom, guarantees the accurate of experimental result;
3. the frustum cone structure of the bottom sealing of trustship upper end that can realize and go to the bottom guarantees that reducibility gas from entering the amount in the crucible, is fully reduced ore;
4. the crucible body is changed simple and convenient;
5. processing technology is simple, and cost is low.
Description of drawings
Fig. 1 is the utility model crucible body profile (1 all passage);
Fig. 2 is the utility model crucible body right view (2 all passage);
Fig. 3 is the profile of the trustship of going to the bottom of the present utility model;
Fig. 4 is that section of the present utility model is always schemed (1 all passages).
Among the figure: 1. external connection screw head, 2. bottom sealing round platform, 3. conical bottom, 4. passage, the trustship of 5. going to the bottom, 6. graphite crucible body.
The specific embodiment
Shown in Fig. 1,2,3,4, the utility model is a kind of graphite crucible device, comprises the graphite crucible body 6 and trustship 5 two parts of going to the bottom.The bottom of graphite crucible body along the circumferential direction is furnished with 1-2 week passage 4 at interval, wherein, crucible bottom is that conical bottom 3 adds bottom sealing round platform 2 structures, go to the bottom trustship 5 for cylindric, the upper end be to seal frustum cone structure with the indent of crucible bottom mating, crucible top is external connection screw head 1, is used for realizing and being tightly connected of last pipe.The graphite crucible body of test sample is housed, cooperates realization sealing between the two by deadweight and the trustship upper end of going to the bottom.Thereby guarantee to detect required reducibility gas and enter the interior quantity of crucible, realized installing easily and dismantling test sample simultaneously.The pyramidal structure of conical bottom 3 has guaranteed that the liquid slag iron that detected iron ore produces can drip smoothly in time, has improved the accuracy of testing result in crucible when fusion takes place.Passage 4 is that reducibility gas enters the interior passage of crucible, is again the passage that liquid slag iron oozes crucible.
Conical bottom with holes of the present utility model adds the structural design that seals round platform, taken into full account the condition of reduction of iron ore soft heat Performance Detection, guaranteed to enter the reducibility gas amount of reduction ore in the crucible from the bottom, can avoid simultaneously the deposition of slag iron drop again in crucible bottom, guarantee that the liquid slag iron that fusion produces can ooze crucible smoothly in time, has improved the accuracy of testing result.
