FAQ

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

 

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

Q:Whether fireclay raw materials or clinker are used when masonrying general fireclay brick? What is the difference between raw material and clinker?
Generally, fireclay used to build fireclay brick is raw materials, it can also use clinker. After calcination, the raw material will shrink, but the brick seam is thin, the deformation has little effect.
Q:How to prevent high alumina refractory brick from producing crack when reproduce high alumina refractory brick?
1-1, on the 1 in order to prevent the emergence of crack in the production of high alumina refractory brick. 2 is appropriate, the water absorption rate of the tube mill should be controlled below 6%, the excess air coefficient controlled between level 1 and 2. The water absorption rate of clinker of bauxite with high alumina controlled under 4%-5%, making the high aluminum refractory brick burning in a smoothly and steadily weak oxidation atmosphere, and should be adjusted by thermotechnic
Q:What are required for high temperature refractory bricks?
good thermal shock resistance:
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:What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?
It can't be the surface of coal, at least it is coal seed.
Q:several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
The life of refractory bricks in rotary kiln is generally short.
Q:What is refractory brick? What is refractory clay? ?
Fire clay refers to the light pouring material, raw materials adopt light porous clinker, bauxite, cenosphere, silicon dioxide ultrafine powder and alumina micropowder. Use calcium aluminate cement CA-80 as binder. Refractory brick is burned from stone powder and clay put in 1300 degrees' kiln
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:What kind of refractory brick is suitable for clinker production line of 2,500 tons?
High alumina brick;
Q:Are refractory bricks, burner block and thermal insulation brick the same? Are they the same thing?
The burner block is heavy, its using temperature is high, while thermal insulation brick is light and its using temperature is lower than heavy brick.
