Aluminous electrobath is production electroanalysises aluminous main unit, by brick of mutiple level fireproof material liner, adiabatic heat preservation combination is formed, introduce aluminous electrobath to use the brick of argillaceous heat preservation of 1 for everybody today, product of light qualitative heat preservation is to reduce heat energy prediction of a person's luck in a given year, heat preservation heat insolation, reduce the negative charge of main body, detailed introduction looks please below.
Brick of argillaceous heat preservation
The working principle of aluminous electrobath
Electrolyte: Cryolite, salt of alumina be in harmony,
Electric current: Dc (4-22kA) ;
Electroanalysis temperature: 950-970 ℃ ;
Electrode: Shade, positive pole all pledges for carbon, aluminium of the separate out on cathode, and CO2 of the separate out on positive pole (70% ) with CO (30% ) gas;
Electroanalysis total reaction: 2Al2O3 (Aq) + 3C (S) =4Al (L) + 3CO2 (G)
The fireproof material application in aluminous electrobath
At present nitrogen changes silicon to combine carborundum material, already was used to replace charcoal brick to apply at material of aluminous electrobath side wall. Nitrogen changes silicon to combine carborundum material although medium carborundum can be in with oxygen below high temperature reaction makes 2 oxidation silicon, but the film of silicon of this 2 oxidation that the surface makes more can prevent combustion of carborundum material continuity. And, nitrogen changes silicon to combine carborundum material to fight cryolite to erode, it is good to fight oxidation function, can add the service life of aluminous electrobath greatly.
Bottom prevents ooze makings and heat preservation brick and siliceous calcareous plate with dry type.
Aluminous electrobath uses the brick of argillaceous heat preservation of 1 is the small qualitative refractory products of AL2O3 content 30%-46% , belong to firebrick of adiabatic heat preservation. Use clay grog or pledge argillaceous grog is mixed gently but model clay is main raw material, mix into is added bond and curium wood chip classics cooperates, mix, shape, dry, firing, use combustible law production. Burden and water mix make but model pug or slop, with extrusion or pouring shape, dry hind in 1250 ℃ - in atmosphere of 1350 ℃ oxidation firing. Dimension of norms of standard of heat preservation brick is 230*114*65mm, can make the product that gets bulk density 0.3~1.5g/cm3, output occupies above of half of heat preservation brick, compression intensity is 2.0-5.9mpa, thermal conductance is 0.221-0.442w/(m.k)(1350 ℃ ) .
Range of application of brick of argillaceous heat preservation is wide, multi-purpose the thermal insulation in hot project facilities and industrial kiln furnace, can use at having stock of melt of intense high temperature to erode to reach erode the place of action, a fireproof coating, reduce the furnace that be mixed by slag to enrage soot to erode, decrease mar, the working temperature of goods does not weigh the experiment temperature of the change that burn a line more than. Brick of argillaceous heat preservation belongs to much stoma kind a kind of light qualitative insulation material. Is porosity of this kind of material in 30% ? 50% , sex of its heat preservation is poor, but mechanical strength is as better as the function that fight corrode.
Introduce here with the brick of argillaceous heat preservation of 1 about aluminous electrobath, hope to be helped somewhat to everybody, my company regards professional firebrick as manufacturer, the product is all ready, firebrick has: Quality of product of brick of argillaceous brick, tall aluminous firebrick, corundum, Mo Laishi brick is good, fireproof material price is substantial, welcome everybody the incoming telegram seeks advice and choose and buy.
