Why Choose Us

l  We are a government owned company with ISO certificate.

l  We are listed in Global Fortune 500 with D & B report.

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 are 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 us 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:How to make refractory bricks and boiler wall adhesion more firm?
If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.
Q:What are the main components of high alumina bricks?
Sweat is like water mineral alumina bauxite, aluminum ore, magnesite, waves of gibbsite. Anhydrous alumina raw material, such as corundum, alumina, fused corundum. High alumina brick Zhengzhou gold company specializing in the production of various specifications, you can directly ask their technical staff.
Q:What are the alloy wear resistance materials?
According to the composition of Beijing Naimo metal materials company will wear resistant metal materials is divided into the following five categories: one: high manganese steel series: high manganese steel (ZGMn13),
Q:How are the high alumina bricks fired?
According to the quality requirements of different grades of high alumina brick, choose different grades of bauxite raw materials, it is conducive to rational use, fine materials, fine distribution, as far as possible not to use mixed grade severe raw materials. The quality of the clinker depends on the calcination temperature, calcination temperature, sintering temperature should be generally reached or slightly higher than that of alumina clinker sintering, to ensure the full and possible high volume density, and the two secondary Mullitization and sintering shrinkage effect in calcination process. Lightweight high alumina brick, also known as high aluminum insulation brick (high-aluminium heat insulating brick). A lightweight refractory consisting of mullite and glass phases or corundum in excess of 48%. The volume density is 0.4 ~ 1.35g/cm3. The porosity is 66% ~ 73%, and the compressive strength is 1 ~ 8MPa. Better thermal shock resistance.
Q:How much is one ton / ton of high alumina refractory brick?
The market price of about super high aluminium brick price at 3000 yuan / ton, a high aluminum brick at around 2500 yuan / ton, two high aluminum bricks at around 2100 yuan / ton three grade high alumina bricks at around 1850 yuan / ton for reference, choose to buy the area is not the same as the prices are not the same.
Q:Which thermal shock stability of clay brick and high alumina brick is good?
Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products
Q:What are the specifications for bricks?
Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
Q:What is the standard classification of high alumina bricks or high alumina bricks?
Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.
Q:What is the difference between metal compounds and metal solid solutions?
A series of intermetallic compounds occurring between transition metals in intermetallic compounds. The most important are L sigma sigma phase and ves phase, they are topologically close packed (TcP) phase, they consist of a small atomic radius of a dense layer, which is inlaid with a large atomic radius of atomic structure, this is a highly dense pile. In addition to atomic size factors, their formation is also influenced by the concentration of electrons.
Q:Use of high alumina refractory bricks?
High alumina brick refractory than clay refractory bricks and brick refractory degree are higher, up to 1750~1790 DEG C, which belongs to high-grade refractory materials.
