Description of fireclay bricks

 

fireclay bricks is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, fireclay bricks is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

 

 

Features of fireclay bricks

Low thermal conductivity       
High refractoriness  
High mechanical strength      
Excellent thermal shock resistance

 

Applications of fireclay bricks

 

fireclay bricks has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

Q:What are the application of used refractory brick pieces?
It can be produced into refractory bricks again, as long as the quality is good. It is much more cost-effective than buying Bayerite.
Q:How many years are the service life of chimney lining refractory brick?
Capacitance magnesite, seawater magnesite, should be the alkaline refractory brick, magnesia-alumina spinel can absorb hydrogen fluoride, generally are magnesia brick, magnesium iron ore, forsterite, dolomite, magnesium dolomite, magnesium silica sand, magnesia-chorme spinel and magnesia chrome sand: Magnesia mineral, magnesium calcium sand, magnesite, magnesium dolomite sand, dolomite, mainly is cordierite
Q:What are the main raw materials of refractory brick and runner brick?
Category of refractory , runner brick mainly is clay brick
Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?
Yes, but the cost is high, refractory material should be the most affordable at present.
Q:How to classify light refractory bricks?
0, perlite insulation brick.2 and so on; according to bulk density, the same lightweight refractory materials can be divided into 0, poly light high aluminum, lightweight brick. Light brick and alumina hollow ball brick.8, 1, 1 light refractory brick generally is classified according to the raw material composition and bulk density
Q:what effect does big mortar joints of the boiler refractory brick have on the boiler?
The ventilation leakage。 Now the larger boilers are generally used refractory pouring material one-time pouring, the arch is easy to collapse . 2, shrinkage and expansion of brick will make the bricks fall. 1, do not use the refractory brick. too large seam will effect the tightness of furnace wall , and the water wall is easy to form dew and be corroded and to leak smoke.
Q:What materials make of clay insulating fireclay brick?
Clay insulation bricks are general according to the different origins of raw materials, not the same
Q:is refractory brick used around the mechanism flue?
Q:Do refractory bricks insulate heat?
Refractory bricks have a certain ability of heat insulation, but its thermal insulation is far less than that of glass fiber and wool.
Q:Is the waste of the fire resistant hazardous waste?
Refractory waste should refer to the used refractory material, which more or less have some pollution. low grade material such as clay brick and high alumina brick can be used repeatedly on the spot, such as breaking it and making it into waste refractory bricks sand, unshaped refractory meterial or low-grade refractory brick, or just bury it in a pit. collect high grade bricks such as corundum brickand silicon carbide brick and sell, they are sought after, the price per ton ranges from several hundred to several thousand. pay special attention not to dispose waste refractory bricks containing metal chromium at random, for it is toxic and carcinogenic. Collect them and seal them up, looking for manufacturers to buy and reuse.
