Description
Technical field
The present invention relates to a burning techniques field of building more particularly to a kind of natural gas kilns and burning with combustion atmosphere control
Make the method for building small cup.
Background technique
Building small cup is one of eight big porcelain in China, claims temmoku teacup in Japan, it is intended that the black glaze tea bowl for firing of putting up a kiln is puted up a kiln
Black glaze small cup.Putting up a kiln is one of eight big kilns in China, and it is rare top grade that small cup is built in transmutation, and small cup is built in existing three transmutation in the world
Product is collected by Japan and is listed as national treasure.Song Dynasty puts up a kiln produced black glazed ware device, and the overwhelming majority is teacup, is referred to as " building small cup ".
The representative that small cup is black glazed ware device is built, was once royal hired tea set in the Song Dynasty.Current research suggests that rise of putting up a kiln is in the late Tang Dynasty five
In generation, is contained in the Song Dynasty, declines in the Yuan Dynasty.It builds small cup to stop after burning centuries, in the 1980s, supporting and being studied more by country's appropriation
The research of mechanism expert successfully has developed imitation Song-Dynasty-style typeface and builds small cup.2011, " small cup of putting up a kiln fires skill " was put into third batch country
Grade non-material cultural heritage register.Build small cup by glaze texture be divided into the writing brush made of rabbit's hair, oil droplet and other textures (francolin spot, coal, sunlight become and
Variegated glaze), tire matter is thick and solid hard, and glaze is simple and unsophisticated, texture change multiplicity.Device shape is tea small cup, and carcass is thick and heavy, and tire color is greyish black；Tire glaze
In conjunction with densification, each small cup glaze texture has uniqueness.
It is a kind of very ancient traditional craft skill that small cup of putting up a kiln, which fires skill, and it is black to refer in particular to Nanping City in Fujian province Jianyang kiln
Glaze tea small cup fire skill, through choosing broken porcelain mine, porcelain miberal powder, elutriation, ingredient, aging, pugging, rub mud, throwing, repaired biscuit, biscuiting,
13 procedure such as glazing, loading of kiln, roasting.Building a burning process mainly includes that bavin burns imperial kiln and electrical kiln reduction technique.In order to protect
The forest reserves, government's explicit order prohibit firewood kiln.According to investigation, it is electrical kiln reduction skill that Jianyang, which is built a burning process and used at most, at present
Art, accounting 90% or so, such as application No. is a kind of method for cooking for building small cup and Shens disclosed in 96100216.6 patents of invention
It preparation and method that small cup is fired please be built disclosed in number patent of invention for being 01139566.4, be realized using electrical kiln.Electrical kiln is
Using electricity as the energy, mostly using electric furnace heating wire, Elema or molybdenum disilicide as heat generating component, by electric energy radiation and thermally conductive principle into
Row oxidizing atmosphere is fired.Fired using electrical kiln, general three to five layers of every kiln, every layer shelve 3 to 10 glazings build small cup, shut furnace
Behind the door, furnace temperature is gradually adjusted to 1300 degree or so.By field research electrical kiln service condition, there are kiln temperatures unevenly to lead
The problem for causing yield rate low, and by power limit, electrical kiln scale is generally smaller, it is difficult to accomplish industrialization production.
Natural gas kiln kiln temperature is uniform, but very high to reducing atmosphere requirement due to building small cup firing, existing natural
Gas kiln is unable to meet demand, therefore is badly in need of researching and developing the novel kiln of a kind of be suitble to put up a kiln small cup and high-efficiency environment friendly and small cup is built in firing
Method.
Summary of the invention

7. according to the method described in claim 5, it is characterized in that, in step (3), keeping 1300 DEG C of constant temperature, t1=60 point
Clock.
8. according to the method described in claim 5, it is characterized in that, in step (3), t2=5 minute, each dosage of natural gas
Be 1 minute for the 4.5Nm3/h(time) to 7.0 Nm3/h(times be 1 minute) between；In step (4), t3=10 minute, day
The right each dosage of gas be 1 minute the 1.0Nm3/h(time) to 3.5 Nm3/h(times be 1 minute) between.
9. according to the method described in claim 5, it is characterized in that, combustion system igniting before, first by the flashboard on chimney top
Biggish aperture is drawn, opens fire door and fire hole, and be in close state all valves, lighting up procedure is successively to open combustion
Combustion gas initial pressure is set in 1kpa by gas imported valve, and the air door for the gas nozzle for needing to light a fire is closed to lesser position,
The valve before gas nozzle is opened, lights a fire, then the air door of regulating gas nozzle, gas nozzle is made to be in best combustion
Burning state；During gas nozzle is lighted a fire one by one, the pressure that pressure gauge is shown can be gradually decreased, regulating gas imported valve
Keep its pressure too low, gas nozzle is caused to be tempered.
