The choice of furnace of kiln of pottery and porcelain

Kiln furnace is the otherwise in ceramics industry production but little device. The sort of furnace of kiln of pottery and porcelain is varied, we undertake differentiating according to modelling normally, its application is in works of ceramics of different production technology.
1, shuttle type kiln: It is intermittent and firing kiln, the structure that follows matchbox is similar, kiln car advances kiln inside firing, burned pull again, debus burns good pottery and porcelain. Kiln car as clip, call shuttle type pit so.
2, channel kiln: It is commonly those who grow is straight channel, its two side and coping have fixed wall and vault, the course of bottom laid is running kiln car on the road. What combustion facilities sets in channel kiln is mid two side, formed fixed tall temperate zone, firing belt, the high temperature flue gas that combustion produces falls in chimney of channel kiln front or the effect that cite fan, flow to kiln head direction along channel, at the same time progressively ground warm-up enters the goods inside kiln, this paragraph of warm-up that made channel pit is taken. Air cooling is roused in the kiln end of channel kiln, inside cooling channel kiln hind a paragraph goods, after the air cooling that rouses sheds classics product and be being heated, take out the heat source that sends desiccator to serve as dry green compact again, this paragraph formed the cooling zone of channel kiln.


3, roller path kiln: Roller path kiln is successive and firing kiln, regard the channel of base substrate means of delivery as kiln with rotational roller. Product of pottery and porcelain is placed in a lot of the level with very close interval is fireproof on roller, rely on the roll of roller to make pottery and porcelain conveys from kiln head to kiln end, call roller path pit so.
4, kiln pouring blaze: The blaze that combustion place produces goes up to support to kiln from the crater of firebox, because kiln is sealed very, blaze cannot continue to go up, below the circumstance of have no way out, by chimney smoke force to pull go downward, through the clearance of saggar column, from kiln bottom Kong Jin suction internal heat raises flue, advocate flue, hind by chimney eduction.
5, ejector plate kiln: Call channel of ejector plate type kiln again, be a kind continuous heat agglomeration equipment, according to the craft requirement of agglomeration product, arrange requires lukewarm area and power, form the hot project part of equipment, contented product is right caloric demand. agglomeration product direct or on the ejector plate that is put in high temperature resistant, wear-resisting to brush secondhand, by advance a system to ask according to the craft of the product on ejector plate to placing the product has shift, the agglomeration process of the product is completed in the chamber of a stove or furnace.


Choose furnace of appropriate kiln of pottery and porcelain, can reasonable use resource, reduce industrial cost. It is the choice of furnace of kiln of 4 kinds of pottery and porcelain below.
1, it is to daily output under 20M3, and line of the products is more, firing temperature each different, as a result of its itself crop satisfies the output of channel kiln hard, recommend use fast and firing shuttle type kiln.
2, be equal to to daily output or be more than 20M3, but its glair color is complex, if kiln becomes crystal,glair needs constant constant temperature and cooling time, can use kiln of traditional shuttle type or pit of type of electric heat shuttle; If kiln changes,glair or crystallization glair are a part only, can choose fast kiln, fast kiln is not only fast, OK also rein in. Slow, difference in temperature is controallable very small. But slow energy-saving effect is poor.
3, bigger to crop, height taller, weight heavier, temperature look of taller, glair is single, can choose kiln of channel of stage car type. Be like pottery and porcelain of high temperature daily expense, defend bath pottery and porcelain.
4, be in to temperature 1300 ℃ less than, the artistic pottery and porcelain with bigger crop, daily expense pottery and porcelain, pottery and porcelain that defend bath, the proposal uses roller path pit, or kiln of type of large and fast shuttle.
