Abstract
The invention provides a glaze for fire door tile of coke furnace its main raw materials in proportion: 80-120-mesh spodumene 35-65%, fine clay powder 2-10%, 200 mesh pyrauxite 15-53%, 200-mesh feldspar 0-10%, and fine pentasodium triphosphate powder 0-1%. In order to improve the glossness of the door brick surface, prevent or reduce the cementation and conglutination between the door brick and tar, make it easy to eliminate the tar and simultaneously meet the use conditions of the door bricks, it adopts spodumene as main raw material. The thermal expansion coefficient of spodumene is 4.0X10 to the power -6 deg.C-1, and as heated to 900 deg.C above, spodumene can convert to beta-spodumene in tetragonal system and generates bulk expansion by about 36%. The thermal expansion coefficient of the beta-spodumene is only 1.9X10 to the power deg.C-1, and thus has very good thermal shock resisting stability.
Description
Technical field:
The present invention relates to a kind of refractory materials, specifically is a kind of glaze of coke oven door brick, also comprises the glaze and the manufacture method thereof of tweel block in addition
Background technology:
Traditional glaze generally all is a ceramic glaze because that coke oven door opens and closes is frequent, in the length of service will through several thousand times from high temperature to low temperature, from low temperature to the pyritous heat exchange, so the glaze of coke oven door brick will have fabulous anti-thermal shock stability.Obviously this is that existing ceramic glaze is not available.In order to make furnace door brick have good thermostability, need its coefficient of expansion lower (general 3～4 * 10
-6℃
-1); And the coefficient of expansion that has only glaze is equal to or slightly less than the coefficient of expansion of furnace door brick, and glaze could combine with brick well.This just requires the glaze of coke oven door brick will have the lower coefficient of expansion.Obviously this also is that existing ceramic glaze is not available.General ceramic glaze thickness has only very thin one deck, and less than 0.1mm, its granularity is also very thin; And as the glaze of coke oven door brick, thickness is preferably in about 0.8～1.5mm, such thickness, and crackle will take place in general ceramic glaze in drying process.
Summary of the invention:
The invention provides a kind of glaze and manufacture method thereof of coke oven door brick, it can solve the problems referred to above that prior art exists.
In order to reach the purpose that solves the problems of the technologies described above, technical scheme of the present invention is: a kind of coke oven door brick glaze is characterized in that its main raw materials in proportion is:
Triphane 80～120 orders 35～65%;
Well as clay fines 2～10%;
Agalmatolite 200 orders 15～53%;
Feldspar 200 orders 0～10%;
Tripoly phosphate sodium STPP fine powder 0～1% (adding).
Selected raw material index is as follows:
| Material name | Al 2O 3 | ?K 2O | ?Na 2O | ?Li 2O | ?IL |
| Triphane | 27.48 | ?6.45 | |||
| Agalmatolite | 20.14 | ||||
| Clay | 35.19 | ?14.23 | |||
| Feldspar | 16.56 | ?10.25 | ?4.74 |
Its main raw materials in proportion is:
Triphane 80～120 orders 35%;
Well as clay fines 10%;
Agalmatolite 200 orders 45%;
Feldspar 200 orders 10%.
Its main raw materials in proportion is:
Triphane 80～120 orders 65%;
Well as clay fines 2%;
Agalmatolite 200 orders 32%;
Tripoly phosphate sodium STPP fine powder 1% (adding).
Its main raw materials in proportion is:
Triphane 80～120 orders 40%;
Well as clay fines 6%;
Agalmatolite 200 orders 53%;
Feldspar 200 orders 1%.
Its main raw materials in proportion is:
Triphane 80～120 orders 65%;
Well as clay fines 10%;
Agalmatolite 200 orders 15%;
Feldspar 200 orders 9.5%;
Tripoly phosphate sodium STPP fine powder 0.5% (adding).
The manufacture method of coke oven door brick glaze is characterized in that comprising the steps:
A by after the accurate weighing of matching criterion, puts into agitator with each raw material, adds suitable quantity of water (adding 35～50%), stirs, and it is stand-by to make glaze slip;
After b will treat glazing furnace door brick or brick blank drying, totally stand-by the surface cleaning;
C dips in hairbrush and gets glaze slip and glaze slip is brushed on the furnace door brick surface thickness 0.2～4mm; Or glaze slip is sprayed on the furnace door brick surface thickness 0.2～4mm with spray gun;
D will advance in the kiln and burns till after will spraying the furnace door brick drying of glaze, and 1250～1400 ℃ of maximum sintering temperatures are incubated 2～10 hours and get final product.
In order to make selected glaze can improve the smooth finish on coke oven door brick surface, prevent or reduce bonding, the adhesion of furnace door brick and tar, make removing tar easy, can satisfy the working conditions of coke oven door brick simultaneously again, the present invention adopts with triphane as main raw material.The thermal expansivity of triphane is 4.0 * 10
-6℃-1, when triphane is heated to more than 900 ℃, can change the β-triphane that belongs to tetragonal system into, and produce and be about 36% volumetric expansion.The thermal expansivity of β-triphane has only 1.9 * 10
-6℃
-1, thereby have good anti-thermal shock stability.Simultaneously, the contraction that the nodulizing owing to fine powder produces has been offset in the expansion in the conversion process, avoids before the glaze fusing because the contraction of glaze makes glaze and adobe disengaging.So the present invention uses triphane as main raw material.
In order to prevent the crackle of glaze in drying process, select for use the granularity of triphane thicker, be generally 80～120 orders.Simultaneously thicker granularity prevents that also triphane from all becoming glassy phase, rather than becomes β-triphane crystalline phase, thereby loses its low expansion character.
In order to make glaze slip have certain suspension, add a small amount of clay, but can not add too much, to avoid producing scasoning check or generation pinprick.
Glaze of the present invention after burning, forms one deck glaze layer on the surface of brick, thereby improves the smooth finish on coke oven door brick surface through smearing or spray to furnace door brick or adobe surface, prevents or bonding, the adhesion of minimizing and tar, makes removing tar easy.Not only improve workman's labor condition and labour intensity.And avoided furnace door brick being damaged owing to removing the tar difficulty.
