All connection relationships not singly refer to that component directly connects, and referring to can be according to specific implementation situation, by adding or reducing connection
Auxiliary, Lai Zucheng more preferably connection structure.Each technical characteristic in the invention, under the premise of not conflicting conflict
It can be with combination of interactions.
Adobe during fabrication, is needed by sequentially connected smoke evacuation area, preheating zone, firing zone, chilling area, slow cooling area, tail
Cold-zone, smoke evacuation area's main function is heating heel row except the mechanical water in green body and adsorbs water, and chemical change does not occur for green body, only hair
The physical changes such as raw volume contraction, moisture evaporation, this area are used to expel from kiln the flue gas that burning generates, balance furnace pressure, flue gas
It is flowed to from high temperature during discharging fume area, heat is constantly released to heating in kiln, and the temperature in area of discharging fume is generally 200 DEG C~600
Change between DEG C；In preheating zone, the temperature of adobe rises to 1050 DEG C or so from 600 DEG C, and brick can be made by suitably adjusting sintering curve
Base safely excludes constitution water, completes the physical-chemical reactions such as quartzy phase transformation, the oxidation of organic matter and the decomposition of carbonate；It is burning
At area, the temperature of adobe rises to maximum sintering temperature from 1050 DEG C, and the salts such as carbonate, sulfate in adobe are in this stage
It further decomposes, completes the physical-chemical reactions such as sintering, porcelain；The main function in chilling area is to be quickly cooled down, the system in this stage
Glass phase viscosity increases in product, and is converted into solid state by mecystasis, and hardness and strength increase to maximum, due to depositing for liquid phase
Product can offset and shrinking the stress occurred, therefore the rapid cooling that can directly dry, convection current is carried out by the cold air squeezed into and is changed
Heat, chilling can not only prevent glaze crystallization, increase product strength and whiteness, improve product quality, and can shorten firing
Period；Slow cooling area is divided into heat exchange zone again and takes out hot-zone, heat exchange zone, by the temperature of adobe from 600 DEG C of slow cooling to 400 DEG C of left sides
The right side makes quartz in adobe slowly complete crystal transition, and " frightened to split " defect, generally uses heat exchange caused by preventing the stress because of rapid cooling
