Product Description:

What is the feature of Fireclay Brick?

l  Fireclay Bricks or fire bricks are the most widely used refractory bricks because of its great features: low thermal conductivity, good thermal insulation performance; High resistance to Thermal shock, abrasion, chemical attack to provide long service life; easy operation and installation; broad usage or applications and low price etc.


l  High density with low porosity fire clay bricks is our featured product in this category. Due to its low apparent porosity rate, high density with low porosity bricks have great features of strong resistance to erosion, high refractoriness under load, great Cold Crushing strength and high mechanical strength etc.

l  We have more than 11 refractory production facilities and bases across China. We have a wide products range, such as ceramic fiber products (ceramic fiber blanket, module, board, paper, bulk), ceramic fiber textile (ceramic fiber rope, cloth, tape, yarn) etc, refractory brick (fireclay brick, high alumina brick, silica brick, magnesia brick etc), monolithic refractory materials, insulating fire brick, calcium silicate board, mica sheet, steel fiber. You can find various products here, and we can combine the light weight ceramic fiber products with the heavy weight refractory brick in one container delivery, then save the sea freight for you.

l  We have strict materials selecting system and quality control system. We have the ability to take responsibility for your orders and product quality.



Q1: How do you control the products quality?

A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.

From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control is conducted by workers and then each piece will be sorted and examined by quality supervisor.


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 as U.S., UAE, Saudi Arabia, Iran, and Russia, etc.


Q4: What is the minimum quantity?

A4: There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need.


Q5: Can you give me a brief introduction of the application of your products?

A5: CNBM (China National Building Material) core refractory business comprises the production, sale and installation of high-grade refractory products, the development and implementation of customized system solutions as well as rendering outstanding services for the key industries in Glass, Iron& Steel, Petrochemical, Cement, Ceramic and Nonferrous Metals.

Q:What is the perservation method for refractory bricks used for cement kiln?
The hydration resistance ability is better than the alkaline materials, 1 years will be no problem if the environment is good, alkali-resistant bricks used in cement kiln brick refractory brick (magnesia-chrome brick, the preservative time will be longer, the remaining products should also be moistureproof. No matter what refractory materials, phosphate brick. If the package is complete, it must be stored in a dry and rain-proof environment, silmo brick. Anti-stripping alumina brick, if is not immediately used, it's necessary to take measures of moisture proof, such as spinel brick must be moisture-proof
Q:The renewal of refractory brick internal the lime kiln belongs to overhaul. In the absence of production, are the replacement of valve and sporadic projects also considered overhauls? Or routine maintenance!
The replacement of fire brick is a major overhaul. If the part causes the furnace shutdown, which is also a major overhaul, so the key of overhaul is depends on what reason it is
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 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:How much is the silica powder in refractory bricks.
It's not easy to construct, also need to consider the technical and economic indexes, DH3, 1 kg silica powder replaces 1 ~ 3 kg cement, which is the reason why silicon powder was not used and spreaded in concrete in past, choose some silica power fume. In general, with the smoke escaping by special capture device for collecting and processing To determine the mixing method of silica powder, when mixing silica powder, you should find out the optimal dosage in order to obtain the best results, as the study, the content is 5% ~ 30%, H, the mixing of super high strength concrete, use same amount of silicon powder to replace equal cement to main same fluidity, Microsilica or Silica Fume, it is mainly according to the design requirements, and does not reduce the amount of cement, sand and stone to adjust the optimal dosage of water reducer, when deciding the best mixing amount of silica fume, the concrete is too sticky, most use naphthalene water reducing agent.
Q:is refractory brick used around the mechanism flue?
Q:Where are clay bricks or cement bricks?
Are clay bricks made of ordinary buildings or clay bricks on refractory materials?. Ordinary clay brick building is a burning clay made of red brick, (that is, the original old house with a little red brick) due to its extensive use of native resources and have great pollution in firing, now in some city has banned the use of the.
Q:What are the specifications of clay brick and cement brick construction?
Clay to clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting and.
Q:Why is the house made of refractory bricks not warm in winter
Refractory bricks are not used in the house, but used in a large boiler inner
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.
