FAQ

Client:what is your company advertage?

 Us:1,  Our company has established a complete quality assurance system,we have been certified by an array of ISO.

       2,  There is almost no black spot on the surface of our bricks. It represents more even and neat color due to the superior raw material and strict selection.

       3,  Our product enjoys higher refractoriness under load because of its higher heat treating temperature in the high temperature zone of the furnace.

Client :why should we choose you?

   Us:we can ensure qualified products only and 100%exfactory pass rate.

Q:Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Heat insulation cotton is laid behind refractory brick.
Q:can diatomite brick be used as thermal insulation refractory brick?
yes, it has good thermal insulation the raw material is cheap, diatomite brick is a kind of thermal insulation refractory brick with good performance.
Q:What kind of material is good to be laid on the kiln car, refractory brick?
It depends on the temperature. General thermal insulation brick is ok, when temperature is high, use mullite, and when temperature is not high, alumina is ok
Q:How to classify light refractory bricks?
Continuous casting use silicious insulation board, silica insulating refractory brick, ceramsite lightweight refractory concrete building block and so on. 0g/ clay lightweight heat insulating brick NGO.4-1.5g/, high aluminum lightweight heat insulating brickLGO.4-0.4-1.7G/, resistance furnace Diatomite brick 0; cm3; cm3; cm3, aluminum oxide insulating refractory products
Q:Are sintered brick concrete bricks?
Fired bricks are not concrete bricks.According to the different production process of bricks into sintered brick and non sintered brick. Sintered brick in China has more than two thousand years of history, is still a very wide range of wall materials.
Q:th choose of different refractory bricks in the rotary kiln
According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
Q:What's the difference between a high aluminum brick and a clay brick, two?
Light clay brick, refractory material is a kind of high porosity, low density, low thermal conductivity of refractory material, refractory materials called lightweight refractories, it includes insulating refractory products, refractory fiber and refractory fiber products. Heat insulation refractory material is characterized by high porosity, general 40%-85%, low volume density, lower than 1.5g/cm3, low thermal conductivity, generally lower than 1.0W (m.K). The utility model has the function of heat insulation of an industrial furnace, and can reduce the heat dissipation loss of the kiln, save energy, and can reduce the quality of the thermal engineering equipment. The mechanical strength, wear resistance and slag resistance of insulating refractory material are poor, and it is not suitable for the load-bearing structure of kiln and direct contact with slag, burden, molten metal and other parts.
Q:What is refractory brick? What is refractory clay? ?
Refractory bricks and refractory soil are all refractory materials. Generally they can be seen in the coke oven. The refractory brick is generally yellow. A steel brick is a kind of refractory brick. Its heavier several times than ordinary brick .
Q:What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?
Coal briquette's effect is also good
Q:How to repair the boiler?
What kind of boiler, the external wall or the furnace arch, the smoke wall, the material: High-alumina cement, refractory brick, refractory clay, knife brick
