refractory lightweight high alumina thermal insulating fire brick

 

Product Description


Refractory lightweight high alumina thermal insulating fire brick is made out of a naturally-occurring material known as bauxite. This material includes aluminum hydroxide, which is what gives the bricks such great warmth resistance. The bricks also include kaolinitic clays, which are roasted to create an unique combination including mullite and also synthetic alumina. This is where the name “high alumina” stems from.


Features

1.High-temperature endurable .

2.Good thermal shock resistance .

3.High cold crushing strength.

4.Good resistance to abrasion and corrosion.

5.Good thermal spalling resistance.

6.High mechanical strength.

7.Good volume stability at high temperature.


Application

1.General use in heat containment unit form temperature 1500-2000°C.

2.Resistant to highest temperature for steelmaking operations such as ladle applications, sidewall, roofs, burner blocks, anchor brick for reheating furnaces and many other areas.

3.transition and cooling zones of rotary cement kilns, lime kilns , etc.

4.lower sidewall and bottom of aluminum refining,melting furnaces ,etc.

Q:Are there any construction waste materials for composite thermal insulation bricks?
The strength products are made of high quality tabular corundum and mullite as aggregate, silicon carbide as matrix, additional special additive and a small amount of rare earth oxide to be mixed, and then formed by high pressure molding and high temperature sintering.
Q:What is the exterior wall insulation material made of graphite?
Graphite is polystyrene board, polyurethane graphite plate, from the point of view of building the acceptance specification in the use process, the core index of insulation material is the heat transfer coefficient and safety, by now a large number of glazed hollow bead slurry from the actual situation it seems difficult to ensure the quality of construction materials should be on site workers slurry mixing, finished product the quality gap made out of very large.
Q:Are there any special requirements for the use of raw materials in thermal insulation brick production equipment? What about the raw materials?
. The control system needs to break, pouring the completion of data acquisition and process control of production site, steam curing process monitoring and control, production line of aerated brick Deyi heavy do better and integrity, production operation management etc..
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: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:Masonry method for boiler refractory brick
Ash bucket (including inclined wall masonry):(1) and an ash bucket masonry first according to drawing find horizontal center line, with the horizontal center line to find out the ash bucket longitudinal center line, coarse slag bucket at the outside edge of the straight wall before and after, based on both ends of the facade vertical center line to pop up the bottom of the ash bucket, ash bucket with bottom opening size of pillar, pop-up vertical auxiliary line using triangle pattern production (according to the drawings, the inclination of inclined wall making) inclined wall paintings in the ends of the facade of the sideline. Use the same material to make refractory concrete inclined wall bottom of the triangle from Taiwan (Figure 1) and straight wall leveling, vertical and horizontal, inclined wall at the junction of the triangle from Taiwan, with the same material refractory concrete filling, until the final setting of concrete masonry wall inclined rear can.(2) and an ash bucket masonry masonry masonry, the first transverse longitudinal component after; inclined wall and straight wall, first built after the straight wall masonry wall.(3), on the back of a foundation by inclined wall, brick and mortar foundation contact surface to be full; inclined wall on the back fill cinder, corresponding to the 2~3 layer of brick masonry masonry, each high, fill a cinder cinder, must reinforce.
Q:What is the bulk density of the sintered bricks?
The Dragon such high aluminum refractory brick density is generally around 1000, heavy refractory brick, high alumina brick HLGX heavy weight in general 2000Kg/m fand.
Q:The project cost in hydropower No.3 shaft wall is solid brick or insulating brick?
Aerated concrete for external walls is to save money. One side is the outer wall.. Solid bricks are the first thing, safety comes first.
Q:What is the function of insulating bricks? Where can I use it?
Low thermal conductivity, high strength, strong durability, simple construction, light weight, easy loading and unloading, economic, green, environmental protection, sound insulation, fire protection and so on.Thermal insulation brick is a new type of energy-saving building insulation technology with inorganic composite material as the main material. It is an ideal technology to replace the traditional wall insulation. The insulation brick integrates the excellent heat preservation effect into the wall while building the wall.
Q:What materials are used for roof insulation
There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
