Method for eliminating dry hanging ceramic plate firing defects

The invention relates to a method for eliminating dry hanging ceramic plate firing defects, which is characterized in that firing ceramic plate composition materials adopt 40 to 65 weight percent of mixed pottery clay, 0 to 20 weight percent of plastic clay, 0 to 15 weight percent of kaolin, 0 to 20 weight percent of feldspar, 10 to 25 weight percent of aggregates with the average grain diameter lower than 24 meshes and common quantity of bounding agents for ceramics. the amount of the pottery clay containing organic matters, sulfides, carbides and the like in the ceramic plate composition materials is reduced, in addition, the porosity after the extruded and formed blank bodies are dried is increased, and the ventilation performance of the blank bodies is improved, so organic matters, sulfides and carbides in the pug can be in the sufficient oxidation reaction to be eliminated in a short time when entering a preheating zone (600 to 700 DEG C), the original short firing period is maintained, the firing black
