Product Description:

nsulating Firebrick is made of high grade bauxite through high temperature calcinations. High alumina brick is a kind of neutral refractory material so that it enjoys excellent resistance

to acid and alkali corrosion. It has characteristic of high refractoriness under load, which decide high alumina brick is a n ideal material for various kinds of industrial furnace. It is widely

used in building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on.

characteristics: 1 Excellent thermal stability
                       2 High refractoriness under load
                       3 Chemical stability and anti-corrision
                       4 Small high temperature creep rate
                       5 Excellent thermal shock resistance

Typical Application: 1 Building materials for blast furnace
                     2 Building materials for hot-blast stove
                     3 Building materials for coke oven
                     4 Building materials for steel making furnace

                     5 Kiln car building
                     6 For ladle 

Product Type: fireclay brick (SK 32, SK 34)
             high alumina brick (sk 35-38)

Package: pallet, thermal shrinkage package

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:What is the difference between cement foamed thermal insulation board and thermal insulating brick?
The main difference between cement foamed thermal insulation board and insulating brick is that the shape is different, one is plate, and the other is brick. Both are new walls to achieve the effect of energy conservation and insulation.
Q:Can fly ash brick keep warm?
Sure, I do fire-resistant insulation bricks, we also use fly ash ah!
Q:What kind of material is clay insulation refractory brick made of?
According to the different origin of general clay brick raw materials are not the same with Henan or Hebei with perlite beads, pyrojewel, use effect and technology of Henan is better than Hebei
Q:Which kind of balcony heat preservation material is better?
To environmental protection, then use inorganic insulation materials, such as composite silicate, rare earth insulation, this thickness should be more than 5 cm, the construction of auxiliary materials, high cost, to be strengthened
Q:If there is a main component of cenosphere light insulating brick.
Light heat insulation brick with cenosphere composition, material properties will be more high, especially the main properties of thermal conductivity
Q:How to do indoor thermal insulation
Indoor thermal insulation, as well as "folk prescription""Some owners also used some of the insulation sleeves, for example, light reflection, heat is also, by means of a reflected heat, indoor temperature increase, the specific approach is adopted, Kouban metal surface, can also use the kitchen stove using metal film or metal film for baking food, installed in the radiator the walls and the walls, so that the heat preservation and reflection cooling effect, but also does not affect the appearance. Again, the 40% heat and window glass heat loss on indoor winter, especially some French families, the feeling of winter indoor temperature is relatively low, methods can be used to paste glass insulation film and coated glass insulation coating to retain heat.
Q:Refractory bricks, burner bricks, insulation bricks? Is it a kind of thing?
Not the same thing, refractory bricks and insulation bricks of raw materials, the proportion is not the same. This is the chain of various types of products
Q:What is the price of fireproof insulation material?
A preliminary understanding of price through online preliminary understanding, now generally the size of the opening of the cable insulation material manufacturers are on business, early online now have a preliminary understanding, manufacturers investigation after considering cooperation.
Q:What is the bulk density of insulating bricks?
Stoneware porcelain water absorption rate is greater than 0.5% and less than or equal to 3%; fine stoneware bibulous rate is greater than 3% and less than or equal to 6%; brick bibulous rate is greater than 6% and less than or equal to 10%; pottery tile water absorption rate is greater than 10%. The water absorption rate of expression: ceramic brick brick >6% = >10% = >3% = fine stoneware porcelain stoneware or porcelain >0.5%
Q:Is sintering insulation brick good or concrete porous brick good?
Thermal insulation brick is functional material, it is better than porous brick in thermal insulation. At the same time, the internal heat preservation material, so the overall cost is more, the hole brick should be higher.
