FAQ

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 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.
Q:What are the main raw materials of refractory brick and runner brick?
Types of refractory bricks are divided into low-grade and high-grade. generally, siliceous, semi siliceous and high aluminous runner brick brick have higher requirements. If it needs to contact melting in high temperature molten steel directly, then it is high alumina(the main raw material is clinker of bauxite with high alumina, corundum( brown corundum and white corundum), the refractoriness is high, lower than 1580 DEG C temperature, but the actual using temperature reaches 1630 DEG C
Q:can the refractory sand be used to make refractory bricks?
refractory bricks can be used as a refractory sand after crushing , no strength required results in the lower intensity, but the temperature is not high, so it is not recommended, but refractory bricks after the high temperature is fine because its properties are changed
Q:Can common cement mortar be used to build the lining of chimney refractory brick?
No. You have used fire bricks, which shows there is a certain temperature inside, you'd better use refractory cement
Q:How to do refractory bricks
Sorting materials -- mixed material - molding - drying - firing embryo
Q:How to test the various components of the refractory brick?
It is difficult to distinguish if it is mixed together, fully smashing and mixing. Then assay. Or testing after smashing and separating.
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:Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Heat insulation cotton is laid behind refractory brick.
Q:What is the material of refractory brick used in the high temperature zone of the kiln?
The ordinary generally use clay high alumious fireclay brick. GB/T 3994-2005 insulating refractory brick. What with good material is high-grade thermal insulation refractory brick. GB/T 3995-2006, high alumina thermal insulation refractory brick , model A13, is made of aluminium oxide, A13 50U, senior heat insulatio brick B5
