Brick of argillaceous heat preservation has what effect, what does main function have?

The main effect of brick of argillaceous heat preservation is the pressure that can ease kiln furnace main wall, reduce prediction of a person's luck in a given year of quantity of heat, managing the sources of energy, in the high temperature environment that can be being used at 800-1200 to spend, density has 0.6/0.8/1.0 to wait.


 The adiabatic and fireproof product of the Al2O30%-48% of brick of argillaceous heat preservation that makes for main raw material with saggar 5 use saggar, float bead, saggar grog serves as raw material, join adhesive and sawdust, mix, shape, dry, fire, can make bulk density 0. .3~1.5g/cm product 3, crop occupies the half above of heat preservation brick.
The function low thermal conductance of brick of light qualitative heat preservation, have favorable adiabatic effect; Low heat is fused, because heat conduction rate is low, mo Laishi series pledges adiabatic brick built up gently a few heat energy, energy-saving in intermittent operation effect is apparent; 3. The oxide content such as the iron box alkali metal of low matter content is very low, because this is fireproof the gender is tall; Contain aluminous quantity high to make its are restoring atmosphere middleman and guarantor to manage good property; 4. Intensity of high fever compression; Exterior size is exact, accelerate build by laying bricks or stones to build career, those who reduce fireproof mud use, assure the intensity of body of build by laying bricks or stones and stability, prolong the service life of liner thereby; Can process special form. Seam in order to reduce bricklaying amount and build by laying bricks or stones.
The manufacturing technology with commonly used brick of argillaceous heat preservation is to join float bead incendiary agent adds content way, also can use bubble method. Application of brick of argillaceous heat preservation is wide, multi-purpose the heat-insulation layer at hot project facilities and industrial kiln, can use at having the place that material of melt of intense high temperature is eroded and erodes. A few have fireproof coat with the exterior besmear that blaze contacts directly, in order to reduce the soot of slag and gas, reduce damage. The working temperature of this product does not weigh the test temperature of the change that burn a line more than. Brick of argillaceous heat preservation is a kind of light qualitative insulation material, have poriferous. The hole rate of this kind of material is 30%〜 performance of its heat preservation is poorer, but mechanical intensity and be able to bear or endure corrode performance is better.
Brick of light qualitative clay gained the favour of manufacturer of most industry furnace with its good performance and low price. Want not to contact blaze directly only, basic it is to use brick of light qualitative clay to replace. What actor drawback does brick of so light qualitative clay have? The heat loss due to radiation of the loss of accumulation of heat of body of industrial kiln build by laying bricks or stones and surface of body of heater occupies the 24~45% of specific fuel consumption to control commonly. Use thermal conductance the light qualitative brick with low, small thermal capacity regards structure of body of heater as material, but managing specific fuel consumption; Meanwhile, because kiln furnace can rise gentle refrigeration quickly, can raise equipment to manufacture efficiency; Still can reduce weight of body of heater, simplify kiln furnace structure, improve product quality, drop environmental temperature, improve working condition.
But porosity of light qualitative firebrick is tall, the organization is inattentive, cannot contact directly slaggy with liquid state metal; Mechanical intensity is low, cannot use at bearinging structure; Wearability is poor, do not suit to be contacted with charging, wear away serious. The safe bearing that brick of light qualitative clay allows in its only just can produce ideal adiabatic result inside temperature limits. Inside kiln, general liner place often is contacted directly with blaze and slag, apply to heavy brick only. Brick of light qualitative clay basically is used at heating up the heat-insulation layer of labor facilities and industrial kiln, can use at having the place that material of melt of intense high temperature is eroded and erodes. A few have fireproof coat with the exterior besmear that blaze contacts directly, erode in order to reduce what slag is eroded and furnace enrages soot, reduce damage. Of course, in be not fusion furnace, do not contact with blaze. Brick of light qualitative clay can be used at temperature upper limit all kiln furnace under brick of light qualitative clay.
