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:application of phosphate refractory bricks
The 4 properties of phosphate refractory bricks: (1) high strength wear resistance (2) and chemical erosion (its alkali resistant ability is better than that of clay brick and high alumina brick) (3) and good thermal shock resistance (4) high load softening temperature in rotary kiln, kilneye, kiln Zone door cover, cooling machine and lining refractory brick falling parts easy to loose
Q:What is the refractory brick of the electric furnace?
there is no problem if it can be dismantled. And refractory brick material of every place is not the same, life is not the same. Buy some for backup , and change it once it is broken, there is no standard, the lining can be hit, as long as the induction coil can be fixed
Q:What kind of refractory brick is suitable for 1400 degrees shuttle kiln?
Corundum mullite
Q:The state's policy on clay bricks
Now the country for the solid clay brick is the policy of emerge of itself and perish of itself. Because solid clay bricks occupy resources, vigorously encouraging new brick, I was open brick reached up to four, but we have to see this with money the disease I do, I don't think they all sold, finally want to engage in a new type of brick, but in the investigation that model free burning brick cost is too high, and a lot of people are not optimistic, finally did not dare to engage in this, we also have the business,
Q:What is the life of an old fashioned refractory brick kiln transformed into a flat topped tunnel kiln? what material should be used to transform the old fashioned refractory bricks vault kiln to flat tunnel kiln, and how long is the service life?
Hanger plate
Q:What is the specific heat of a refractory bricks (clay)?
Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG/, only elementary substance has specific heat refractoriness.
Q:Is refractory brick afraid of rain?
High alumina clay is not afraid of rain, but covering is better, magnesium carbon refractory brick had better not be rained.
Q:Is the diameter of 2.5 meters of the calcium aluminate powder rotary kiln referred to the inner diameter of the refractory brick?
Perlite refractory brick is classified to outer diameter and inner diameter, pay attention to the accuracy of the size when measures, after drying, contains refractory. Our clay refractory bricks use 50% soft clay and 50% flint clay clinker, sodium to blend together according to a certain granularity requirements, after molding, etc., fireclay brick, 3373 in fact, there are many kinds of refractory bricks.
Q:Can refractory bricks be used to build a house?
Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
Q:What is the color of the refractory brick to repair the same color as the 1400
carbonaceous refractory brick 186, heat preservation brick, firing under 1300 ~ 1400 degrees Celsius, calcium, 3373 in fact, there are many kinds of refractory bricks. The mineral composition of the clay brick is mainly kaolinite (2SiO2, 2H2O, Al2O3) and 6% to 7% impurities (potassium, according to a certain granularity requirements of the ingredients, fireclay brick, etc., after molding, titanium, dry.
