Product Description:

Introduction of insulating firebrick

Insulating brick is sintered mainly with supper-fine bauxite charlotte and propr additive by a method of EPS ignition loss. Refractory high alumina EPS insulating brick for heating furnace is a kind of insulation refractory product, taking bauxite as main raw material and including not less than 48% of AL2O3.

Characteristics of insulating firebrick

1.High porosity

2.Small volume density

3.Good insulation effect

4.High mechanical intensity

5.Small thermal conductivity

6.Long service life

 

Application of insulating firebrick

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. For construction material in steel industry

6. For ladle

FAQ

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.

Q:What is the difference between cement foamed thermal insulation board and thermal insulating brick?
1, cement foam insulation board, as its name says, is "board", it is used on the exterior wall or roof, that is, the grass-roots has been done, and put a plywood outside, you can achieve the effect of insulation;2, insulation brick, mainly brick, it can be directly wall masonry, wall completed, the insulation effect is reflected.
Q:Why does the water drop first and then rise when the boiler fires?
This is the reason for the zero water level gauge line below the center line of the drum. Under normal conditions for water and evaporation is balanced, after the fire, reduce the amount of steam water mixture into the drum in the evaporation decreased rapidly, reduce the volume of water bubbles, sudden contraction, drum water level decreased rapidly. But not to water change or increase (automatic), water balance is broken, the water level will rise rapidly.
Q:What is the function of insulating bricks? Where can I use it?
Thermal insulation bricks are mainly used in toilets, kitchens, TV sets, bedrooms, walls and so on. And brightly colored, various specifications, can be cut at random, the section neatly.
Q:Does the building with the exterior wall thermal insulation brick require adding an angle steel bracket in the middle of the brick?
The first thing the man has to do is to do the quality test in front of the wall. As for the second, there is not much to do.
Q:Are there any construction waste materials for composite thermal insulation bricks?
Material production of ordinary light insulating brick clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating refractory brick, diatomite insulating refractory brick.
Q:What is composite sintering insulation bricks?
Taking the Yangtze River, lake and silt as the main raw materials, the performance indexes of roasting are in line with the technical specifications and technical requirements of the building blocks, referred to as insulating bricks.
Q:Insulation brick should pay attention to external walls?
In each segment or block the tiles are from bottom to top paste, from the line of position the next layer of hypodermis first brick hidden good ruler, to hold the first leather tiles, pull in tile lines as the upper skin paste standard.
Q:Are there any special requirements for the use of raw materials in thermal insulation brick production equipment? What about the raw materials?
Specific funding, different production, different raw materials configuration will be different. According to the design requirements, refining production process, for production process, production management level, complete monitoring, pulping system on the lower computer, based on control level; lower machine by the programmable controller (PLC) is mainly composed of a crushing system. The host computer takes the standard industrial control computer (IPC) as the main man-machine interface (HMI) and beating system, and if possible, it is recommended to investigate on site
Q:Which kind of balcony heat preservation material is better?
New inorganic insulation material, this material thickness is thin, in 2-3 centimeters line, direct smear on the top of the house, without auxiliary materials, the price is higher than rock wool, aluminum silicate cotton.
Q:What are the sizes of lightweight thermal insulation bricks?
The production of material ordinary lightweight insulating refractory brick with fireclay and high alumina high strength bead brick
