Product Description:

65% Al2O3 Min High Alumina Insulating Fire Brick     


High alumina insulating fire brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

This series of High Alumina Insulating Fire Brick are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature. 


Product Applications:

High alumina insulating fire brick are ideal for use in the below applications 

Building materials for blast furnace

Building materials for hot-blast stove

Building materials for coke oven

Building materials for steel making furnace

For construction material in steel industry

For ladle


Product Advantages:

CNBM has success in its High alumina insulating fire brick due to their cost-effectiveness and excellent insulating properties. The refractoriness of magnesia chrome bricks are more than 2000°C, and the refractory under load is a above 1550°C.Good steady volume in high temperature, the performance of meeting sudden cold and sudden hot is better than magnesia bricks. 


Main Product Features:

Excellent thermal stability

High refractoriness under load

Chemical stability and anti-corrision

Small high temperature creep rate

Excellent thermal shock resistance

 Refractory High Alumina Thermal Insulating Fire Brick



Q1: Are you a manufacture or trader?

A1: Factory+trade (mainly for manufacturing, also do some business of related products).

Q2: What's the MOQ of trial order?

A2: No limit,We can offer the best suggestions and solutions according to your requirements.

Q3: After an order is confirmed,when to deliver?

A3: According to your order quantity, normally, 15-25 days after deposit received.

Q4: Is your company accept customization?

A4: We have our own factories and excellent technical team, and we accept OEM service.

Q:What are the types of building blocks?
Ordinary housing: building brick (clay brick), and non sintered brick (sand lime brick, fly ash brick, cement brick, etc.)
Q:What are the sizes of lightweight thermal insulation bricks?
Low iron mullite, high aluminum light insulating refractory brick, diatomite insulating refractory brick. Sizes can be customized for ordinary profiled sizes
Q:The insulation layer destroyed after use of cement paste and tiling
Put on the insulating layer and paste it with cement.Some students worry about the insulation layer and the wall adhesive strength is not enough, do not worry about, now developers are building exterior insulation and then on top of the tiling. Because after finishing the insulation layer, the contractor should check the construction to do a pullout test, the purpose is to prevent the strength can not meet the requirements.
Q:What are the specifications of high strength diatomite insulating bricks?
Exterior wall decorative plate is made from polystyrene resin as raw material and other raw materials and polymer content, by heating mixed with catalyst, rigid foam board and plastic extrusion molding and manufacturing, has moisture-proof, waterproof performance, can reduce the thickness of building envelope, thereby increasing the use of indoor space.
Q:What is a JQK composite lightweight thermal insulation brick?
Its characteristic is waterproof and heat insulation, thermal insulation performance, strong decoration, waterproof effect is good, and good weathering resistance, long service life, the whole system of simple construction, low cost, is a new type of inverted waterproof and insulation structure of the current system state key application.
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:What are the insulation materials for heating buried pipelines?
The heat preservation layer is composed of antirust paint, heat insulating material, moisture-proof layer (used for pipeline in the trench), protective layer, anticorrosive layer (used for trench or directly buried pipe) and top coat (or fireproof coating).The waterproof layer can be used asphalt or aluminum foil protective layer with glass cloth or galvanized steel.
Q:Masonry method for boiler refractory brick
In accordance with the construction procedure of from bottom to top, from the inside to the outside of the drum and the lower part of the principle of convection tube flame plate concrete when the interval is from top to bottom.
Q:What is the bulk density of the sintered bricks?
Sludge brick density is about 1000Kg/m or so fand.
Q:What is the bulk density of insulating bricks?
National classification standard: water absorption rate of ceramic tile is less than or equal to 0.5%;
