Abstract
The invention discloses a firing technique for enhancing kiln transformation ratio of Nixing pottery, which comprises the following steps: 1) putting a dried billet into a kiln, gradually heating to 50-100 DEG C, and keeping the temperature for 24-36 hours; 2) heating to 500-600 DEG C by 55-70 DEG C an hour; 3) heating to 750-850 DEG C by 90-110 DEG C an hour, closing the air holes of the kiln, and adding the kiln transformation material into the kiln; 4) heating to 1080-1150 DEG C by 90-110 DEG C an hour, wherein the heating speeds of the heating tubes are sequentially lowered from bottom to top in the kiln; and 5) cooling, and taking out the fired billet. In the high-temperature firing stage, the temperature difference appears in the kiln, so that the atmosphere of the reduction reaction is more violent; and the temperature is raised once an hour, so that the temperature in the kiln is changed, thereby enhancing the kiln transformation ratio.
Description
Technical field
The present invention relates to the sintering technology of pottery, be specifically related to a kind of sintering technology that improves the emerging pottery kiln of mud variability.
Background technology
The transmutation of the emerging pottery of Qiezhou mud, refer to the variation of color and luster and the lines of made-up article, the eastern mud that mud emerging pottery in Qiezhou is used, include abundant iron oxide composition, due to iron valency element oxidation with reduce in different firing atmosphere, valent variation is different, as+3 valencys ,+divalent, add unburnt smog in fuel, introduce carbon element deposition, make made-up article variable color abundanter, on the basis of original rust, indistinctly present the multiple color and lusters such as bronze, purplish red, ashen, golden yellow, blackish green, sky blue, maroon, and the texture variations such as day spot, brave line.Transmutation is magical because changing unpredictably, precious because of " asking precious in fire, rare one " again.Although the generation of the emerging pottery transmutation of mud has very large accidentalia, find that by research principal element has two: the one, iron oxide content, the 2nd in pug, the reduction firing atmosphere of ferric oxide in sintering procedure.After testing, ferric oxide generation reduction reaction occurs at 950～1140 DEG C, in the emerging pottery sintering procedure of traditional mud, in the time entering high-temperature firing, is all to fire at a temperature spot, and reduction atmosphere is inactive, is the problem place that transmutation rate is not high.
Summary of the invention
Technical problem to be solved by this invention is to provide the emerging pottery of a kind of mud and burns till that rate is high, the sintering technology of the emerging pottery kiln of the coloury raising mud of transmutation variability.
For achieving the above object, the technical solution used in the present invention is as follows:
A sintering technology that improves the emerging pottery kiln of mud variability, comprises the following steps:
1) warm kiln: the base substrate after drying treatment is put into kiln, temperature is increased to 50～100 DEG C gradually, and continue 24～36 hours at this temperature;
2) will be through excess temperature kiln base substrate after treatment, intensification per hour once, heats up 55～70 DEG C at every turn, is raised to 500～600 DEG C;
3) will be through step 2) base substrate after heating up, with intensification per hour once, heat up 90～110 DEG C at every turn, be raised to 750～850 DEG C, and at this temperature, the pore of sealing kiln drops into transmutation material in kiln simultaneously;
4) again with intensification per hour once, the heat-up rate of 90～110 DEG C of at every turn heating up, is raised to 1080～1150 DEG C, and the heat-up rate of the heat-generating pipe that distributes from bottom to up of kiln reduces successively, and the temperature of kiln is reduced from bottom to up successively;
5) after cooling, the base substrate being fired into is taken out, complete firing of base substrate.
Different from existing design is, extend the time of low temperature temperature kiln, in this process, wake earth up, discharge moisture, and montmorillonite is 100 DEG C of left and right, start dehydration deformation occurs, because low-firing phases-time is long, temperature is low, montmorillonite dehydration is slow, and deformation quantity is low, can not cause slight crack, ensure the rate of burning till.At high-temperature firing stage (more than 850 DEG C), temperature in kiln reduces from bottom to up successively, in kiln, there is temperature head, make the atmosphere of reduction reaction more violent, and intensification per hour is once, also make the temperature in kiln occur changing, and unlike the sintering procedure in the middle of existing, be slowly progressively to improve Heating temperature, the atmosphere variation of reduction reaction is low.
Preferably, in step 4) in, the temperature of lower floor's kiln can be higher than 30～80 DEG C of middle level kiln temperatures, and the temperature of middle level kiln can be higher than 30～80 DEG C of upper strata kiln temperatures.Best, the temperature of lower floor's kiln is higher than 50 DEG C of middle level kiln temperatures, and the temperature of middle level kiln is higher than 50 DEG C of upper strata kiln temperatures.
Preferably, in order to improve the rate of burning till, fire the stage in middle temperature, in step 2) in, will be through excess temperature kiln base substrate after treatment, can intensification per hour once, heat up 60 DEG C at every turn, be raised to 550 DEG C.
Preferably, in step 3) in, can be with intensification per hour once, heat up 100 DEG C at every turn, be raised to 800 DEG C.
In step 3) in, transmutation material can be pine branch, injected volume is that 100～150g is thrown in every cubic metre of kiln space.The pore of closed kiln, reduces the inflow of oxygen, and the smog that contains carbon monoxide that pine branch produces is flowed in kiln, and base substrate is formed to carbon element calmness.
Compared with prior art, the present invention has the following advantages:
1, the time of low temperature temperature kiln is long, temperature is low, and slowly, deformation quantity is low in base substrate dehydration, and shrinking percentage reduces, and reduces fission rate, has ensured the rate of burning till;
2, in the high-temperature firing stage, in kiln, there is temperature head, make the atmosphere of reduction reaction more violent, and intensification per hour is once, also make the temperature in kiln occur changing, improve transmutation rate;
3, by the pore sealing of kiln, reduce the inflow of oxygen, extend the time of the burning of transmutation material, increase carbon element calmness, further improved transmutation rate.
