Abstract
A kind of iron ore molten drop trial furnace graphite crucible, the collet mouth of pipe on crucible collet, the crucible collet being connected by the passage of the mouth of pipe on graphite crucible body, graphite crucible body, graphite crucible body lower end, graphite crucible body lower end forms, its graphite crucible body lower end is truncated cone, is provided with graphite crucible and gets dress groove on the inwall below the mouth of pipe of graphite crucible body; The collet mouth of pipe on crucible collet be shaped as the shape matching with graphite crucible body truncated cone lower end, on the inwall at crucible collet middle part, be provided with crucible collet and get dress groove.The utility model is that graphite crucible dress gets conveniently, can significantly reduce the damage of graphite crucible and crucible collet, maintenance is reduced and maintenance cost can significantly reduce, and good seal performance between upper and lower, is difficult for producing leakage phenomenon.
Description
Technical field
The utility model relates to a kind of crucible, specifically belongs to a kind of iron ore molten drop trial furnace graphite crucible.
Background technology
It is the one that belongs to iron ore high-temperature metallurgical performance that iron ore high-temperature melt-dropping property detects, and it mainly detects between the softening beginning temperature of iron ore, softening finishing temperature, softened zone and the temperature of dripping.This test does not have national standard, only has implementation method, when test, the sintering deposit of designated size is put into crucible, and the upper strata of stock column and lower floor, with addition of a certain amount of coke, put into the crucible that installs sample in molten drop stove and heat, reducing gas N
2: CO=70:30 enters iron ore is reduced from crucible bottom, until reduction soft melting dropping occurs ore.There is drippage temperature and be generally 1450 DEG C ~ 1500 DEG C in ore, and after ore reduction, forms the slag iron crucible that easily bonds, and each test all needs to change a crucible, and test consumption is larger.
Through retrieving: the patent documentation that Chinese Patent Application No. is 200820185315.8, it discloses " a kind of graphite crucible device ".A kind of graphite crucible for reduction of iron ore soft heat Performance Detection equally, the feature of this crucible be high temperature resistant, can drip smoothly from bottom ventilation, liquid slag iron, can realize and the trustship effective sealing of going to the bottom by deadweight, crucible top is external connection screw head.But the external connection screw head on this crucible top design inconvenient operation and be easy to damage in the time being connected with the upper seal of tube, graphite crucible is got inconvenience with the trustship dress of going to the bottom, while using crucible tongs dress to get, top crucible easily drops and smashes the crucible collet of bottom, the opening part tube wall of trustship of going to the bottom is equally very thin, dress is easy to breakage while getting top crucible, has not only caused the waste of test consumable also the cost plenty of time to be changed to processing to testing equipment.
Chinese Patent Application No. is 201120163345.0 document, it discloses " a kind of iron ore high-temperature molten drop determination device ", in this patent, mention the graphite crucible using in molten drop determination device, the graphite crucible of mentioning in this patent only has one section, sample ore is placed in crucible, and top and the bottom are provided with graphite cake.There is inconvenience for setting-out sampling in this kind of crucible, and this graphite crucible only has one section, and local loss all must be changed together, causes huge waste.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of graphite crucible dress to get conveniently, significantly reduces the damage of graphite crucible and crucible collet, reduces the iron ore molten drop trial furnace graphite crucible of maintenance.
Realize the technical measures of above-mentioned purpose:
A kind of iron ore molten drop trial furnace graphite crucible, the collet mouth of pipe on crucible collet, the crucible collet being connected by the passage of the mouth of pipe on graphite crucible body, graphite crucible body, graphite crucible body lower end, graphite crucible body lower end forms, it is characterized in that: graphite crucible body lower end is truncated cone, on the inwall below the mouth of pipe of graphite crucible body, be provided with graphite crucible and get dress groove; The collet mouth of pipe on crucible collet be shaped as the shape matching with graphite crucible body truncated cone lower end, on the inwall at crucible collet middle part, be provided with crucible collet and get dress groove.
Feature of the present utility model: graphite crucible dress is got conveniently, significantly reduces the damage of graphite crucible and crucible collet, reduces maintenance and maintenance cost can significantly reduce, and good seal performance between upper and lower, is difficult for producing leakage phenomenon.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
In figure: 1-graphite crucible body, 2-mouth of pipe, 3-passage, 4-crucible collet, 5-collet mouth of pipe, 6-graphite crucible is got dress groove, and 7-crucible collet is got dress groove.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
A kind of iron ore molten drop trial furnace graphite crucible, the collet mouth of pipe 5 on crucible collet 4, the crucible collet 4 being connected by the passage 3 of the mouth of pipe 2 on graphite crucible body 1, graphite crucible body 1, graphite crucible body 1 lower end, graphite crucible body 1 lower end forms, graphite crucible body 1 lower end is processed as truncated cone by it, and processing graphite crucible is got dress groove 6 on the inwall below the mouth of pipe 2 of graphite crucible body 1; The collet mouth of pipe 5 on crucible collet 4 be shaped as the shape matching with graphite crucible body 1 truncated cone lower end, and it two is plug-in type connected mode between this; On the inwall at crucible collet 4 middle parts, process crucible collet and get dress groove 7.
When test is used, extend out spring crucible tongs hook with bottom and get on dress groove 6 at the graphite crucible of graphite crucible body 1, the graphite crucible body 1 that sample is housed is placed on crucible collet 4; The interior wall-hanging insertion between the two of the collet mouth of pipe 5 of the truncated cone lower end of graphite crucible body 1 being inserted on the crucible collet 4 coordinating with it is not closely leaked, and during with guarantee test, reducing gas used does not leak; Reducing gas reduces to sample through the passage 3 of crucible collet 4 and graphite crucible body 1 lower end, drips from passage 3 until sample is reduced into liquid iron.After having tested, available bottom extends out spring crucible tongs hook and gets on dress groove 6 and take out graphite crucible body 1 at the graphite crucible of graphite crucible body 1, if crucible collet 4 is damaged in process of the test, can take out equally replacing.
This detailed description of the invention only exemplifies for the best, not the restricted enforcement to technical solutions of the utility model.
