Description
Technical field
The present invention relates to test mould technical field more particularly to a kind of combinations for the test of pressed machine brick static state resistance to slag
Formula mold.
Background technique
Molten steel furnace external refining technology is more next to be popularized, such as LF refining, RH refining, VD refining and VOD refining, due to these essences
It is relatively high to refine temperature, refining slag can be reacted with residue pile generates a large amount of eutectics, such as CMS2 (1391.5 DEG C of fusing point), C2MS2
(1454 DEG C of fusing point), CMS (1498 DEG C of decomposition), C3MS2 (1575 DEG C of decomposition) etc., these eutectics take off under molten steel souring
It falls, fire resisting working lining thickness is caused to reduce rapidly, there are great security risks, therefore, are tested by anti-slag and grasp refining slag
For the erosion condition of residue pile, suitable scheme and the reasonable working lining thickness of design can choose to adapt to refining ring
The optimization collocation of raw material is realized in border under the premise that security is guaranteed.
But traditional anti-slag test mould has the disadvantage in that first, during batch turning, mold is easy to be expected " punching
", mold is caused to be disposed across in pressed machine brick；The second, after carrying out static anti-slag test, the center of crucible cannot be correctly found
Line is cut, and is caused data analysis inaccuracy, and traditional moulds are truncated conical shape, can not be determined survey after center line incision
The original diameter in position is measured, the case where scouring can not be accurately compared.
