The origin of name of all-purpose arc brick:
The arc of all-purpose arc brick is semicircle, another end is groove, no matter ply how many, the metropolis is agile motor-driven, because he does not have an axis, dimension has deviation a little, same also can build by laying bricks or stones becomes a circle.
All-purpose arc brick that my company produces basically is used at blast furnace, hot-blast stove, furnace of charcoal element roast, furnace of charcoal element to calcine, jiao Lu, contain steel barrel, mould system, boiler, cement kiln, vitreous kiln and facilities of all sorts of kiln furnace liner and hot project, apply to metallurgy, mechanical, building materials, cast, pottery and porcelain, electric power, oil, the industry such as chemical industry.
Norms of all-purpose arc brick reachs size:
All-purpose arc brick basically regards Cheng Gang as bucket liner, give priority to character with clay before, be replaced by tall aluminous brick gradually now,
All-purpose arc brick has following each advantage:
1, service life is tall, brick of more grog clay raises 210 ％ .
2, the case that from the unit the quantity that control cost drops, show the advantage of tall aluminous all-purpose arc. And of unit wastage reduce, and accountable of metalloid in molten steel field trash decrease accordingly.
3, break those who face slag and molten steel to erode brick of clay of counteractive excel much grog from what tall aluminous brick checks after extensive is used.
4, all-purpose arc firebrick has circularity as a result of two end, when bricklaying can. Around shift moves section circularity, reason build by laying bricks or stones builds firebrick advantage, the brick is seamed can achieve 1 millimeter commonly.
5, perpendicular brick seams all-purpose arc brick lesser, relatively seam continuously with standard firebrick decrease 70% , move up and down to molten iron layer so and thorough brick seams erode action to get amendatory.
6, as a result of firebrick improvement in quality, can reduce thickness of small line brick, rose accordingly to fill steel tub capacity.
7, grow as a result of service life, bricklaying is convenience, reduce choose and employ persons of tub of steel of the build by laying bricks or stones after furnace to be versed in consequently, raise the utilization rate of steel tub.
Norms of all-purpose arc brick and dimension express as follows:
All-purpose arc brick already was replaced now common straight form brick, all-purpose arc brick that my company produces by advantage:
(1) intensity of normal temperature compression is high, wear-resisting caustic.
(2) be able to bear or endure chemical aggressivity is good, especially acidity and slaggy.
(3) rate of high temperature creep is low.
(4) fight flake performance is good.
(5) curved section but swing, when bricklaying can around shift moves section circularity, reason build by laying bricks or stones builds firebrick advantage, the brick is seamed can achieve 1 millimeter commonly.
(6) reduce thickness of small line brick, rose accordingly to fill steel tub capacity.
(7) perpendicular brick seams all-purpose arc brick lesser, relatively seam continuously with standard firebrick decrease 70% , reduce the use amount of fireproof mud, save cost of bad news material.
(8) dimension but custom-built into aleatoric length.
The characteristic of all-purpose arc brick: Have fireproof degree of tall, changeless form, appearance is neat, drip smooth, be able to bear or endure burst apart the gender is good, do not flake reach fight aggressivity strong, dimension accurate, breed is all ready. Brick of all-purpose arc line basically is used at furnace of kiln of furnace of kiln of boiler of blast furnace, electric stove, hot-blast stove, heating power, glass, cement, chemical fertilizer to make gas oven, cast reach irrigate steel to wait with the brick.
