The invention relates to the technical field of glazed tiles, in particular to a firing process of glazed tiles, which comprises the following steps: sequentially carrying out primary firing, flameout and water drainage and secondary firing on the primary glazed tile blank in a kiln. The invention can overcome the defects that the tile body is easy to deform and crack and more defective products are caused by the existing glazed tile sintering process.
Description
Technical field
The present invention relates to glazed tiles technical fields, and in particular to a kind of firing process of glazed tiles.
Background technique
In recent years, Chinese people occupies condition and is significantly improved, and people also start to pursue high-grade living conditions, many places
People build the single villa formula building of oneself, and the roofing of these buildings mostly uses greatly glazed tiles.
Clay is mostly used to prepare greatly the solid glazed tiles making material sold currently on the market, firing speed is general
At 11 days or so, and exist for the non-clay glazed tiles of hollow structure, internal structure and making material and clay glazed tiles
Apparent difference will be due to sintering procedure if firing such glazed tiles using traditional glazed tiles process for calcining again
Temperature rise is too fast and generates a large amount of substandard products, and some glazed tiles even can also torsional deformation or upper and lower unbaked tile junction generation cracking
Deng.Therefore, it is necessary to the firing process to the non-clay glazed tiles with hollow structure to improve.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of firing process of glazed tiles, existing to overcome
There is glazed tiles firing process bring watt body easily-deformable and cracking and the more defect of defect ware.
A kind of firing process of glazed tiles proposed by the present invention, the technique include the following steps:
S1, loading of kiln: it will be sent into stove by surface using the glazed tiles first product that glaze pour glaze completion, and by glazed tiles
First product is layered stacked neat and opening down, and the spacing of every piece of glazed tiles first product is 10-15mm, staggeredly puts between every layer
It sets, is separated above and below at interval of layer 2-3 with partition；
The glaze is preferably prepared by the raw material of following parts by weight: lead frit powder 84%, Lip river tin rouge and powder end 10%,
When preparation, raw material is mixed in proportion for kaolin powder 6%, and it is mixed that water is added according to the ratio that mixture and water are 1:4-5
It closes, and stirs evenly, to pour glaze immediately after mixing evenly, and to scrape off extra glaze after pouring glaze；Remaining glaze is packed into envelope
It closes in bucket, to pour glaze before use again after mixing evenly；
S2, envelope kiln: after loading of kiln, with brick by stove door termination, and clay mud 3-5mm is smeared by brick outside envelope kiln brick
It seams and closes tightly；When stove door termination, the square kiln temperature that position reserves that side length is 100-150mm among main wicket is observed
The closing brick in hole, peep hole lower edge stretches out 100-150mm, and it is vertical to be usually close to peep hole on the outside of peep hole using 2 pieces of bricks
It places to block closing；
S4, firing: successively once being fired, flame-out to discharge water, secondary firing；
S5, flame-out cooling: after the completion of firing, closing all fuel valves, and stove stops working rear venting natural cooling；It closes
When fuel valve, air compressor and air door are not closed, using burner to being aerated in stove, the air of ventilation
Amount is maintained at air capacity when primary firing；
S7, finished product kiln discharge: 4-6 days opening stove doors after stove is flame-out fill the brownish red glazed tiles finished product of firing
Vehicle kiln discharge, and it is in barnyard in heaps neatly packed；Kiln temperature must be checked before kiln discharge, when touching patch wicket non-scald on hand with the back of the hand
Kiln discharge；When kiln discharge, the quality of finished product coloured glaze semicircular tile must be examined and reject underproof defect ware.
Preferably, in the primary firing, firing time 8-10d, highest firing temperature is 740-750 DEG C.
Preferably, the concrete operations once fired are as follows: be warming up to 110-120 DEG C for first day, fire 2d；Third day rises
Temperature fires 2d to 250-300 DEG C；It is warming up within 5th day 450-500 DEG C, fires 1d；It is warming up within 6th day 600-620 DEG C, is fired
1-2d；It is finally warming up to 700-750 DEG C, fires 2-3d.
Preferably, in the primary firing, first day heating rate is 18-24 DEG C/h.
Preferably, the flame-out time to discharge water is 6-8h.
Preferably, the flame-out concrete operations to discharge water are as follows: after the completion of primary fire, all fuel valves are closed,
After stove is flame-out, all air holes and Draw off valve at the top of stove are opened, discharged water to stove and are drained in stove all
Steam.
Preferably, in the secondary firing, firing time 7-8d, highest firing temperature is 1050-1060 DEG C.
Preferably, the concrete operations of the secondary firing are as follows: be warming up to 780-800 DEG C for first day, fire 2d；Third day rises
Temperature fires 2d to 880-900 DEG C；It is warming up within 5th day 980-1000 DEG C, fires 1d；It is warming up within 6th day 1050-1060 DEG C, is burnt
2-3d processed.
Preferably, in the secondary firing, first day heating rate is 156-266 DEG C/h.
A kind of firing process of glazed tiles provided by the invention, is divided into and firing twice, and in sintering procedure, in stove
Temperature gradually rises and is kept for certain firing time in each temperature section, can effectively improve the yield rate of glazed tiles, make to burn
The defect ware rate of glazed tiles after is greatly lowered, and quality of finished product good, intensity are high, clear, entire body no color differnece, surface
It is highly polished without blackspot, it is unlikely to deform and cracks.The operation is simple and convenient for burning process of the invention.
