General Information

CMAX insulating firebricks are classified under temperature between 1300℃ to 1700℃, manufactured from high purity alumina clay.

1. Lower content of iron, alkaline and impurities, good high temperature properties.
2. Homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles.
3. High strength, good thermal shock resistance under high temperature.
4. Precise sizes due to grinding and shaping after sintering, which meets the requirement of construction.
5. Max service temp: Up to 1730C (3160F)

 

Feature
Light weight and low thermal conductivity    
Low heat storage  
Low iron and impurities  
High thermal shock resistance

 

Application of Insulating brick

Metallurgical Industry: blast furnace, hot blast furnace, heating furnace, etc..

Petrochemical Industry: ethylene cracking furnace, hydrogen furnace, the main furnace, heating furnace, etc..

Ceramic industry: roller kiln, kiln, etc..

Glass industry: glass furnace regenerator, etc.

Carbon industry: carbon furnace, etc..

Aluminum electrolysis industry: aluminum reduction cell, etc.

Other industries: tunnel kiln, shuttle kiln, etc.

 

Advantages of heat insulation brick

Low thermal conductivity: many air holes will bring good thermal insulation effect, energy saving.

High crushing strength: high crushing strength, volume stability.

Low heat storage: small heat storage, absorb more heat, energy-saving effect is obvious.

Common problem solution

1. What products do you have?

We have all kinds of refractory bricks, refractory casting materials, mortar, cement, ceramic fiber products, etc..

Or you can browse our products to choose what you need.

2. How to control product quality?

With strict quality control system throughout the material selection and production process, we have the quality of refractory materials and ceramic fiber products to meet customer requirements.

From the selection of raw materials, the quality of our control to start. The quality of the raw materials required for each batch of products in the use of the front line test. In the production process, through the quality control of workers, and then to each piece of classification, and through quality supervision and inspection.

3. Could you give me a brief introduction to the application of your product?

My Company is mainly engaged in steel, cement, glass, ceramics, petrochemical, electric power and other industries.

4. If I need you, what kind of information do you need?

Q:Why does the water drop first and then rise when the boiler fires?
Often in the operation of the boiler, the steam water mixture to the drum after intense evaporation of a large number of bubbles in the water side, the water volume expansion. By actual water level drum water level indicator is higher than the water level
Q:Energy saving bricks or bricks?
Insulating bricks are mostly hollow or light bricks.It can be said to be energy-saving bricks, including insulation bricks
Q:What is composite sintering insulation bricks?
The brick belongs to the porous brick and has good heat preservation performance. Reached the national 50%~65% energy efficiency standards. High safety (no crack, no seepage), strong durability (with building life), economy (self insulation, no need to increase the cost of insulation).
Q:Refractory bricks, burner bricks, insulation bricks? Is it a kind of thing?
The burner brick is heavy brick, the use temperature is higher, the insulating brick is light brick, the use temperature is lower than the heavy brick.
Q:Are there any special requirements for the use of raw materials in thermal insulation brick production equipment? What about the raw materials?
Pulping, pouring system, but if you want to invest in you know more about this knowledge, according to your production decision, cutting system and steam curing system, mainly for operators, grinding, grinding system, production control system uses two typical control methods.
Q:What is the price of refractory bricks
Insulating brick is a refractory brick often used in kilns to reduce the heat loss of kilnsSo as to ensure the practical efficiency of kiln and bring more benefits.There are many kinds of thermal insulation bricks, and there are many refractory manufacturersAs to how much bricks should be paid, a detailed consultation should be made to the refractory bricks manufacturerHave some understanding of the properties, technologies, raw materials and so on, and make a decisionDifferent types of insulation brick prices are different, the price is relatively cheap, lightweight clay insulation brick 1The market price is 1.3 yuan a pieceThe price of mullite heat preservation brick 0.8, the market price of 4.62 yuan a pieceDepending on the area, the price of insulating bricks will fluctuate somewhat
Q:Difference between inorganic insulation material and organic thermal insulation material
The main difference between inorganic insulation materials and organic thermal insulation materials is that the types of insulation materials are different:1, inorganic insulation materials, including glass wool, rock wool, expansion perlite, micro nano insulation board;2, organic insulation materials are mainly polyurethane foam, polystyrene board, phenolic foam and so on.
Q:What's the price of lightweight refractory bricks?
Insulation bricks according to size, material, performance of different prices are not the same, the same products in different regions also vary slightly
Q:Is it necessary to abolish the technical regulations for the construction of self thermal insulation masonry building with sludge sintering insulation bricks?
Silt sintering brick insulation brick is made from river mud, city sludge, mud as the main raw materials, added according to a certain proportion of siliceous inorganic binder after aging, extrusion blank, blank by cutting, drying, sintering and extrusion molding machine. The utility model has the advantages of energy saving, resource saving, favorable for developing circular economy and comprehensive utilization of resources, high micropore rate, good product heat insulation performance and heat insulation performance, etc..
Q:Are there any differences between insulating bricks and refractory bricks
Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.
