Description
Technical field
The present invention relates to ceramic processing technique fields, and in particular to a kind of composite ceramics prefabricated component, especially one kind have
Thermal conductivity is low, long-lived, wear-resisting and self-cleaning property ceramic preform.
Background technology
Currently, the positions such as traditional coke oven door and tedge are by small-sized clay or Jin Celadon stone laying fireproof bricks
It forms, since there are many puzzle joint, is easy product coke, carbon distribution at puzzle joint in use, with being repeated for reaction, puzzle joint holds very much
Easily it is extended, with the expansion of puzzle joint, the closed and heat-insulating property rapid decrease of fire door runs cigarette, runs dirt, oozes coke thereupon,
Not only it had caused environmental pollution but also had wasted the energy.Moreover, the mechanical strength and thermal shock performance of traditional fire door material are poor, the longevity is used
Life do not grow, later maintenance is frequent, and the tar and dust being attached on fire door are difficult to clean up, need continual input manpower,
Material resources are safeguarded that later maintenance is costly.
Traditional tedge, lower part use clay or the small brick masonry of cordierite, top bridge tube to use cast iron pipe more more, and there are the longevity
It orders short, closed and poor thermal insulation property, be easy the problems such as coking and carbon distribution, both be easy to cause gas leak, pollute environment, and exist
Security risk, later maintenance is difficult, and maintenance cost is higher.
Traditional stoke hole mostly uses clinker tile, and heat insulation is very poor, and energy waste is serious, and is easy after a period of use viscous
Coking oil is degrading the working environment of furnace roof, causes environmental pollution to cause closed not tight, run away with fire and sparkling etc..
