Description
Technical field
The present invention relates to technical field of refractory materials, relate in particular to a kind of modular tile and preparation method thereof.
Background technology
Hotblast stove is to produce the Thermal Equipment that hot blast is provided, the working conditions change that its burner port position material must be born high temperature and rapid heat cycle for blast furnace ironmaking.
At present, ceramic burner mouth is mainly mullite trichroite by the material of modular tile both at home and abroad, but mullite cordierite is due to trichroite granularity and add-on is unreasonable, materials are single, cause soft on the low side, the reheating of the lotus of modular tile to shrink large, high volume less stable, thermal shock is not so good, thereby affect the over-all properties of modular tile.
And for the production method of modular tile, generally adopt the artificial ramming of brick one mould, female brick mechanical processing method, machine to press or monomer brick is produced in machine pressure-vibratory compaction etc., then each monomer brick is assembled.Monomer brick produce to be unable to do without mechanical pressing or ramming process, inevitably causes molectron globality to decline, and occurs that tissue odds, slabbing, apparent porosity are high, the not high defect of compactness.
Continuous research through to modular tile production technique, has proposed a kind of new technique-moulded technique at present.First the moulded technique of modular tile make gypsum the female brick of monolithic, again the female brick of gypsum is combined into integral body, and mark intersection according to drawing requirement, utilize machine tool to excise redundance along intersection, thereby obtain the whole plaster mold of the modular tile consistent with designing external form, dimensional requirement and the sub-brick of monomer gypsum, after split, by the sub-brick of gypsum, rout up gypsum master mold, thereby obtain gypsum master mold.Moulded technology utilization gypsum be easy to the feature of processing, be the many curved surfaces of brick one mould, external form complexity is difficult to the special shaped brick of producing, and has found production shortcut.Due to the many curved design of brick one mould, without mechanical pressing brick output gradient error, thereby the finished bricks external form, the size that obtain are accurate, there is good globality, design brick is with brick checks and balance, intermeshing locking, and brickwork joint meets design requirement completely, nothing three angle seams, in use, eliminate generally and to become flexible, be shifted, peel off, fall brick phenomenon, life-span and Integral synchronous with brick.
