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:What kind of material is good to be laid on the kiln car, refractory brick?
Use blankets to suspend ceiling, and modules for wall
Q:What material are used to burn firebrick?
Alkaline series of refractory bricks /, can be classified into five types. Refractory bricks are generally made from refractory clay (white clay) or other refractory materials. Refractory brick according to the composition of refractory material, that is, silicon aluminum refractory brick / carbon containing refractory brick / thermal insulation refractory brick/ zirconium containing refractory brick /
Q:How to count the number of loading refractory bricks?
Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
Q:how much is the content of the high alumina of refractory brick?
linear change on reheating is small and Slag resistance is good, matte smelting, good thermal shock resistance used refractory materials should be resistant to high temperature: In front of the furnace, the temperature can reach 1800, copper blowing. The maximum temperature in the smelting furnace area is on the top, pyro-refining and electrorefining, magnesia chrome brick, magnesia chrome castable, magnesia alumina brick. The commonly used refractory materials is direct-bonded magnesia-chrome bricks, which has large volume density. manufacturing technique of copper smelting consists of five parts, Clay brick
Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of brick has the highest refractory temperature?
It depends. if high alumina brick is used in kiln, its temperature is above 1700 degree, clay brick is between 1500 degree to 1750 degree, magnesia bricks and magnesia-chrome bricks are about 1500 degree to 1650 degree.
Q:How to wipe off the white paint on the refractory brick (red).
Wallpaper knife should be ok
Q:Which is best of refractory brick press machine?
Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
Q:What is the upper limit of high temperature resistance of refractory bricks and refractory soil?
In a variety of colors; if it has small amounts of Ti4 and Fe2, then it is blue, vanadium and other trace elements, brown red color, which include red, yellow and other colors, the Ural mountains of Russia; corundum is aluminum oxide (Al2O3)mine. Some crystals contain six symmetrical distribution and other needle like rutile inclusions, they are called star ruby or sapphire stars, but because they often exist fracture, black and other colors on the bottom surface of the colorless or rhombohedral decent form polysynthetic twin, a drum shaped six square column, iron, yellow, blue and green, the color of sapphire is decided by the chemical composition contained in titanium, no cleavage, gray, yellow sapphire etc.. Sapphire often is known for its color name, such as white sapphire, sky blue, including South Africa as the main origin of the Transvaal, more than 1500 sapphire calls corundum, brown. Corundum has glass luster, and is common seen in alluvial placer, purple, named ruby. Produced igneous and metamorphic rocks, which are relatively barren. Sapphire is all colors corundum gems except red series of corundum gems. Does ruby refer to corundum with all red hues? No, violet sapphire is mainly used as high-grade abrasive, its red is mainly caused by the chemical composition of trace elements chromium, blue sapphire is the most popular in the world, pink. The crystal belongs to the three party system, green. Usually it is white, gold sapphire, are precious gems, they can produce six star awn, some are needle or clintheriform, green sapphire. Aggregation is block or columnar.
Q:the amount of per square refractory brick of Various specifications and thickness of the refractory brick wall
9 grams-47. 7 grams- 47 calculate by your own according to the actual volume; cubic centimeter; 2.2 grams Clay brick 2: 1; 3, high alumina brick 3; cubic centimeter; standard density, cubic centimeter: 230mm * 114mm * 65mm, diatomite insulation brick 0, you can calculate the reference value
Q:Should refractory cement hang inner core when use carbon steel pipe make water heating hearth by self?
I think it shouldn't. There is no refractories used for circulation pipe inside the boiler, and there is how long distance between pipe and coal fire
