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 are conducted by workers and then each piece will be sorted and examined by quality supervis

 

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: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:Is the waste of the fire resistant hazardous waste?
it mainly depends on whether the refractory bricks contain chromium, if not, we only need to properly dispose of them, it would cost less and assure that there is no bad effect on people and the environment, shoot two hawks with one arrow; if there is hazardous elements like chromium and mercury, it may cost much and be disposed as industrial waste(or construction waste) by local environmental protection department, it is ok if there is a large amount of waste, because the environmental protection department will not take those waste that is not obviously dangerous seriously, even if it is dangerous waste. If there is no suitable manufacturers. It is better to look for a refractory brick manufacturers to recycle it, the cost is acceptable if the amount is small. In general, these heavy metal containing refractory bricks need to be disposed by the company that has quality to dispose such hazardous waste.
Q:How to increase the service life of high temperature refractory bricks?
The wedge brick should contain the brick surface distortion, decrease scrap rate high temperature refractory brick is refractory with a certain shape and size, the error of symmetry and concentric reducer's size differences. The correctness of shape of the straight refractory brick should include the straight of the intersection and the distortion of brick's face. Under the premise of ensuring the service life, the key to improve the efficiency of manufacturers, and have the correct shape and precise size. This is to ensure that the product is qualified, refractory brick in addition to planning a reasonable scale, that is, the scale of the allowable error.
Q:Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?
There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.
Q:Do you use ceramic as offal material for refractory bricks?
Use special clinker of bauxite with high alumina as main ingredient, pulp, K2O < 0, the main component is Al2O3 which is more than 18%, it is a kind of neutral refractory material, pyrophyllite fine powder doesn't need refractory brick production process, Fe2O3 < 1, grinding - mixing - molding - sintering - packaging - delivery. A.3%.3%, Fe2O3 < 0, molding and calcined from bauxite or other raw materials with high content oxides, combined with clay, K2O < 0.5%; 3: 2, raw materials 1; 4: 325 mesh.0%:
Q:What is the refractory brick in silicious model?
Adding appropriate amount of mineralized agent to promote the transformation of quartz in the body into phosphorus quartz. Smaller coefficient of thermal expansion. Also used in high temperature bearing part of hot blast stove and acid open hearth furnace, refractory materials and ceramic kiln, kiln vault and other load-bearing parts, thermal shock resistance variation. High temperature strength. the glass furnace is burnt in 1430 to 1350 degrees Celsius in the reducing atmosphere. use natural silica as raw materials. True density 2. more than 93% of silica content. generally there is no crystal type transformation above 600 degrees celsius. With acid slag erosion and sediment chamber regenerator performance, soaking furnace, open hearth furnace. there is more crystal type transformation below 600 degrees celsius. mainly used in coking chamer of coke oven and partition of firebox. acid refractory material made of high thermal shock resistance, large volume change, square quartz and a small amount of residual quartz and glass box . Long term use at high temperature without deformation
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:Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
Now is the best thermal insulation hollow powder briquette, because it is hollow, blocking the heat transfer, plus foam insulation on the outside, good insulation effect,
Q:How to make refractory bricks? ? ?
Can knock, use angle grinder to slowly cut off the glaze layer outside the refractory brick, and then use hand to gently tap, to compare the complete China to do the work of the destruction of the situation
Q:The brick and ordinary clay brick which is expensive
Of course expensive materials sintered clay brick, sintered clay brick fired common clay, shale and shale and coal gangue as raw materials by high temperature firing,
