Product Description:


High alumina fireclay Brick for Heating Furnace 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 fireclay Brick for Heating Furnace are made of selected high alumina bauxite, kaolin clay, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature


Product Applications:

1. Furances of glass,coke oven,electric and so on
2.Furnaces of metallurgy industry, heat treatment furnace
3. Furnaces of chemical industry and construction industry.
4. Furnace of incineration of garbage, recirculating fluidized bed furnace


Main Product Features:

1. Low porosity,High bulk density.

2. High Cold Crushing strength.

3. High refractoriness under load.

4. High mechanical strength.

5. Good resistance to erosion.

Q:Characteristics of refractory bricks
The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear change on reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.
Q:What type of refractory brick won't deform or crackbe for a long time in the temprature of about 1600 degrees?
1. , mullite poly light ball brick type, andalusite brick type: MJ-1600 MJ-1700 the temperature is higher than 1600 C. 3, the refractory bricks that won't deform or crack in the 1600 degrees Celsius for a long time includs the following several commonly used bricks: GMZ-80 GMZ-75 the temperature is higher than 1650 DEG C, 2, corundum mullite brick type
Q:Lining of refractory bricks in rotary furnace
About 7000~10000 furnace in steelmaking, the level of maintenance and management of each plant is different! Refractory thinning relates to safety issues (equipment and people safety). i am not clear about zinc smelting! Zinc smelting may use rotary kiln! blow the zinc powder into the kiln.
Q:buliding method of refractory bricks in boilers
Q:What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
Q:Why is there cracks in the use of refractory bricks?
Several reasons for the emergence of cracks: (1) temperature difference stress (2) mechanical stress (3) crystal type change stress
Q:does the electric kiln burner need to be sealed?
seal when open the kiln, and observe the temperature, when the temperature reaches a point, you can move the firebrick away, and continue observing the temperature to decide whether to seal it or not, but do not seal it completely, repeat the procudure until reach the sinter point or skill requirement.
Q:How to count the number of loading refractory bricks?
Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
Q:How to adjust the temperature in the 160 meter tunnel kiln?
Tunnel kiln can be attemperated by burning products, this will not affect the firing of different products, and can burn back processing products.
Q:What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?
Coal briquette's effect is also good
