The thermal shock effect of cold anxious heat, makes it be highly vulnerable to breakage, not only directly influence the converter smelting period, STEELMAKING PRODUCTION rate, pushing off the slag effect,
Steel quality, and safety in production is influenced huge.
Tapping hole sleeve brick is generally in hot lower repairing and replacement, after sleeve brick is replaced, need to be carried out in gap between sleeve brick and brick cup
Grouting, high temperature sintering, achieve the purpose that tamp.The new stove of converter uses as a servant first tapping hole, and installation is complete in the cold state, using bulk
Refractory matter hole between tapping hole sleeve brick and brick cup is filled；Since operation gap is narrow and can not synchronize carry out high temperature sintering
Processing, therefore can not be tamped between tapping hole sleeve brick and brick cup, there is gap in various degree, in tapping process, molten steel often occurs
Leakage phenomenon, leads to that the sleeve brick service life is low, even production disruption.
Utility model content
To solve the above problems, the utility model provides a kind of novel converter tapping hole sleeve brick, built for the new stove of converter
Cold conditions is installed during building, and is avoided that molten steel leakage in opening new furnace tapping process, improves the sleeve brick service life.
The specific technical solution of the utility model is as follows：A kind of novel converter tapping hole sleeve brick, it is by cylinder I and cylinder II
Composition, cylinder I are made of refractory material with cylinder II, are fitted to each other by fire resisting filler material and tapping hole brick cup；The cylinder
Body I has cavity with axially disposed in the middle part of cylinder II；The cylinder II is set on the inside of Converter, cylinder II outer diameter φ 1 ratios
I outer diameter φ of cylinder, 4 small 20-150mm.
Further, I section configuration of cylinder is round or oval, outer diameter φ 4 according to BOF nominal capacity,
Brick cup internal diameter is designed, and I outer diameter of cylinder is compared with the small 2.0-5.0mm of I internal diameter of tapping hole brick cup；Cylinder I (1) length is than tapping hole seat
The short 100-300mm of the sum of brick I (6), tapping hole brick cup II (7) length.
Further, II section configuration of cylinder is round or oval, and II length L1 of cylinder is 100-300mm.
Further, the cavity section configuration is round or oval, and diameter is according to BOF nominal capacity and stream
Steel time requirement is selected, and cavity diameter φ 2 can be identical with cavity diameter φ 3 at cylinder I or be differed at cylinder II.
Compared with prior art, the beneficial effects of the utility model are：A kind of novel converter tapping hole sleeve of the utility model
The structure of brick is simple, makes and easy to use, different using cylinder I, II outer diameter of cylinder, carries out gap separation, molten steel is avoided to ooze
Leakage achievees the purpose that improve the sleeve brick service life, promotes molten steel quality, steady production；The sleeve brick of the utility model increases out simultaneously
Hole between steel mouth sleeve brick and brick cup is easily installed construction filling fire resisting material.
