Fireproof and pouring makings and firebrick are high temperature resistant material, it is the material in the quantity with industrial kiln commonly used furnace, one belongs to adventitious fireproof material, one is belonged to finalize the design fireproof material, is phase of two kinds of data compared under what advantage to have?
Above all pouring expect by material qualitative cent has light qualitative, medium heavy qualitative, heavy qualitative, by material qualitative cent has tall aluminium qualitative, clay qualitative, corundum qualitative, Molaishi carborundum is qualitative, qualitative etc. Every kinds pouring makings have the advantage with distinct oneself.
Say here pouring makings total advantage;
One, fireproof degree, loading bate temperature is high
2, heatproof shake performance is good, be able to bear or endure urgent cold urgent heat
3, construction is convenient, managing cost
1, production of tall aluminous aggregate is fireproof and pouring makings do not need the huge machine that press a brick and firing hot project facilities, the factory covers an area of an area small, accordingly, facility cost and capital construction investment all are compared low;
2, the sources of energy is used up little, it is the 1/15~1/20 of firebrick only;
3, labor intensity is low, manufacturing efficiency compares firebrick tall 3~8 times;
4, finished product facilitates store and carry, can realize mechanization to build furnace, the tall 5~15 that applies labor efficiency to compare bricklaying times;
5, can aleatoric modelling, make integral line system, can raise 30%~150% of its service life, some is as high as severalfold; Do not have juncture at the same time, air-tightness is good, heat loss due to radiation is little, but many managing energy resources;
6, can repair kiln furnace, prolong its service life, raise furnace exercise to lead. Accordingly, tall aluminous aggregate got rapid development in adventitious fireproof material.
Fireproof and pouring expecting is one kind does not need to shape, firing the fireproof stuff with liquidity is had better after the agitate that add water. Its structure is expected by aggregate, pink and glue agent is made up by craft scale and become, can replace form complex, different degree tall, area is vast wait for different changeful goods place to replace with, have construction convenient, shorten time limit for a project, ease the good point such as labor intensity.
Pledge gently fireproof and pouring expect the rigid that belong to water is pouring makings, apply to flue of furnace of kiln of glass of law of thermal insulation of all sorts of kiln furnace liner, float sealed and pouring makings, have coefficient of thermal conductivity function of low, adiabatic heat preservation contractility of good, line is small, pouring integral sex is good, dry strength is good wait for a characteristic. Pledge again fireproof and pouring makings is main use as liner of facilities of hot project of industrial kiln furnace and sealed material.
Divide clay, tall aluminium, inorganic by bond function kind fireproof and pouring makings, they part to issue the characteristic that achieves oneself performance with water rigid and high temperature condition, fireproof and pouring makings have acid-proof strength tall, fight erode, heatproof shake sex, wear-resisting, fight flake, apply to crucible of furnace of the Xiaogao in cement kiln, labour frequency chamfer of frit of electric induction furnace, soaking furnace to decoke is overspread, blast furnace wind runs rotary kiln and the place such as all sorts of flue, acerbity, chamfer.
Use range: Channel of frit of metal of coloured of the aperture of furnace door of heating furnace of line of wall of industrial cellar furnace or thermal insulation of line of back of furnace of cellar of high temperature industry, report, double examine, brick that burn chew, black, chamfer.
Fireproof and pouring expecting is the compound that becomes by the graininess material of different grain and cementing material configuration, it is certain to when using, be joined proportional water mixes, shape, the calm profile stuff that gets after sclerosis, belong to avoid agglomeration product; Firebrick is shape by the pug classics of different material, fire of dry, high temperature and into, belong to agglomeration goods. Fireproof concrete and firebrick photograph are compared, simplified workmanship, reduced manufacturing cost, make furnace equipment has good integral sex and performance characteristics. Fireproof concrete and firebrick are in performance characteristics is photogenic finish a good point than having one:
① is fireproof degree adjacent or a bit under coessential firebrick;
Temperature of ② loading bate is lower than coessential firebrick more;
Coefficient of ③ linear expansion is small, because cementing material is in hot-working process,expand with the heat of aggregate balance disappear;
Tall; of intensity of ④ normal temperature
⑤ is able to bear or endure burst apart quality (heatproof shake sex) good, than coessential firebrick good;
⑥ apparent pore is led a bit under firebrick, but shut air hole much, send density to be inferior to firebrick; consequently
The heavy systole that burn a line compares ⑦ commonly firebrick is big.
