Problem is wasted in great graphite material.
Therefore, how to be reduced as far as the waste of graphite material, reduce iron ore Molten drop test cost, become this field skill
Art personnel technical problem urgently to be resolved.
Utility model content
To solve above-mentioned the technical problems existing in the prior art, the utility model provides a kind of iron ore Molten drop test group
Box-like graphite crucible can effectively solve the waste of graphite material existing for iron ore Molten drop test graphite crucible in the prior art and ask
Topic.
Thus the utility model discloses a kind of iron ore Molten drop test combined type graphite crucible, including Crucible body and
Crucible bracket, wherein the Crucible body is composed of crucible crucible body and crucible crucible bottom, and crucible crucible bottom is connected to described
Crucible bracket, and crucible crucible bottom is equipped with dripping hole.
Further, in the iron ore Molten drop test in combined type graphite crucible, the crucible crucible body is top under
Portion is open columnar structured, and crucible crucible bottom is the combination with open cylinder-shaped upper part and closing reverse frustoconic lower part
Structure.
Further, in the iron ore Molten drop test in combined type graphite crucible, the lower part of the crucible crucible body is circumferential
Inner edge is provided with internal screw thread, and the top circumferential direction outer rim at crucible crucible bottom is provided with external screw thread, the internal screw thread and the outer spiral shell
Line is mutually matched engagement.
Further, in the iron ore Molten drop test in combined type graphite crucible, the closing rounding at crucible crucible bottom
Platform shape lower part is formed with the first chamfering, and the top circumferential direction inner edge of the crucible bracket is equipped with the second chamfering, first chamfering with
Second chamfering, which cooperates, to be coupled.
Further, in the iron ore Molten drop test in combined type graphite crucible, the top of the crucible crucible body is circumferential
Inner edge setting is fluted.
The advantages of iron ore Molten drop test of the utility model combined type graphite crucible, is, is combined by the fractionation of crucible
Formula design, after this iron ore Molten drop test, crucible crucible body can be backed out from crucible crucible bottom, which can be at it
It is reused and being combined with new crucible crucible bottom in iron ore Molten drop test afterwards, it is possible thereby to reduce stone significantly
The waste of ink material reduces iron ore Molten drop test cost.
