Abstract
The utility model is a kind of molten drop stove chamber structure, including graphite trustship, crucible, graphite bush, crucible connector, and cushion cap is arranged in crucible inner nosepiece wall, places antispray casing on cushion cap, antispray casing is the hollow tube for having thickness.The outer diameter of antispray casing matches with the cushion cap diameter of crucible connector.The beneficial effects of the utility model：Solve the problems, such as that graphite bush, crucible connector cannot reuse caused by melting splash, reduce waste, also reduces the working strength of testing crew, improve test efficiency, and antispray sleeve can reuse, and the cost that each molten drop is tested is made to be reduced.
Description
Technical field
The utility model belongs to iron charge metallurgical test field, is related to the molten drop stove of iron ore reflow conductor roll detection.
Background technology
Iron ore molten drop stove burner hearth is made of graphite trustship, graphite crucible, graphite bush, crucible connector etc.（Fig. 1）, it is molten
The special burner hearth for dripping stove, mainly for detection of the swell increment of iron ore, softening section, pressure difference, melting zone, the drop for going back Primordial Qi
Fall the important parameters such as temperature, be evaluate sinter, pellet blast furnace process performance a kind of important testing equipment.
Under normal test conditions, after the completion of the experiment of iron ore molten drop, by crucible（Together with the iron ore test sample in crucible）It is useless
It abandons, crucible connector can be reused with graphite bush.But existing molten drop stove burner hearth has the drawback that：Iron ore is in high temperature
After melting, splash is also easy to produce in the case where the pressure of also Primordial Qi pushes, splashings easily spray crucible connector, in splash to graphite bush,
So that crucible, crucible connector and the black casing of stone is adhered to together, can not detach, it can only be by graphite bush, crucible connector and crucible one
With discarding, the great waste of crucible connector and graphite bush is caused, and frequently dismantle molten drop stove burner hearth, also increase examination
The workload for testing personnel, reduces test efficiency.
Utility model content
The purpose of this utility model is to provide a kind of novel molten drop stove chamber structures, it is intended to use this chamber structure can be with
Prevent in iron ore high-temperature fusion splashings splash to graphite bush, avoids the waste for causing stone black casing and crucible connector, play
It reduces experimentation cost and improves the effect of test efficiency.
The technical solution of the utility model：A kind of molten drop stove chamber structure, including graphite trustship, crucible, graphite bush, earthenware
Crucible connector is arranged cushion cap in crucible inner nosepiece wall, antispray casing is placed on cushion cap, antispray casing is to have certain thickness side
The hollow tube of wall, the hollow tube are open up and down.The outer diameter of antispray casing matches with the cushion cap diameter of crucible connector.
The antispray casing height is 15cm, and the height that antispray casing stretches into crucible connector is 2cm-3cm.It is placed on
The length 13cm or so of crucible connector can be extended on crucible connector.
The antispray casing is alundum tube or graphite-pipe.It is suitble to using discarded alundum tube or graphite-pipe intercepted length
Segmentation both may be used.
The beneficial effects of the utility model：1, the utility model places antispray casing on original crucible connector platform,
Be transformed it is simple and practicable, it is convenient to carry out.
2, the antispray sleeve material of the utility model is corundum or graphite, these materials are to be easy to get in metallurgical laboratory
Product do not need to buy, it is only necessary to which, by what is discarded, diameter intercepts one section of 15cm or so with the comparable alundum tube of Graphite nipple or graphite-pipe
Hollow tube.
3, the utility model, which fundamentally solves graphite bush, crucible connector caused by melting splash, cannot repeat profit
With the problem of, reduce waste, also reduce the working strength of testing crew, improve test efficiency, and antispray sleeve
It can reuse, the cost that each molten drop is tested is made to be reduced（About 2000 yuan/time or so）.
Description of the drawings
Fig. 1 is molten drop stove chamber structure before transformation；
Fig. 2 is molten drop stove chamber structure after transformation；
In figure：The trustship of 1- graphite, 2- crucibles, 3- graphite bush, 4- crucibles connector, 5- antispray casings.
Specific implementation mode
As shown in Fig. 2, a kind of molten drop stove chamber structure, including graphite trustship 1, crucible 2, graphite bush 3, crucible connector 4,
Cushion cap is set in crucible inner nosepiece wall, places antispray casing 5 on cushion cap, antispray casing is to have in certain thickness side wall
Blank pipe.The outer diameter of antispray casing matches with the cushion cap diameter of crucible connector.
Antispray casing height is 15cm, and the height that antispray casing stretches into crucible connector is 2cm-3cm.Antispray casing
Length 13cm of crucible connector or so can be extended by being placed on crucible connector cushion cap.
The antispray casing is alundum tube or graphite-pipe.It is suitble to using discarded alundum tube or graphite-pipe intercepted length
Segmentation.
