Product Description:

GENERAL INFORMATION:
Fireclay bricks are made from clinker clay by mixing, forming, drying, sintering and machining. The Al2O3 content ranges from 36% to 42%.
Fireclay bricks feature stable mechanical strength and good thermal shock resistance, withstanding high temperature up to 1750.
They are commonly applied as refractory lining directly exposed to heat or backup insulation layer in all kinds of industrial kiln or laboratory furnace.

ADVANTAGES:
Low thermal conductivity
High refractoriness
High mechanical strength
Excellent thermal shock resistance
Non standard sizes and shapes are available upon request

APPLICATIONS:
Petrochemical process heater
Heat treatment furnace
Ceramic firing kiln
Cement rotary kiln
Glass melting tank
Backup insulation

Q:what kind of refractory brick is suitable for 1300 degrees converter?
High alumina bricks of above 3 grade, containing more than 60% aluminum
Q:is it correct that the higher the refractoriness is, the better refractory bricks are?
Not completely correct. Refractory bricks need to be strong in addition to the fire resistance.
Q:What is the refractory temperature of refractory bricks?
First look at the used parts of refractory brick, anti stripping performance, these are the most basic performance factors, the refractory temperature of high alumina brick is 1770 -1790 degree, the refractory temperature of clay brick is 1380-1570 DEG C, record the anti acid corrosion data of refractory bricks, the compressive strength of refractory bricks, at the same time, you should analyze each part of the furnace pH index and sintering temperature of working. When purchasing refractory bricks, you need to pay attention to many factors, high temperature creep property, softening temperature under a fixed load, 6548, volume stability at high temperature. Because the production of the product is affected by the weather and fuel energy, etc.. 186, select the suitable refractory bricks
Q:What are the main components of refractory bricks
Mainly is magnesium oxide, sodium silicate as a binder
Q:What is the color of the refractory brick to repair the same color as the 1400
Smash the same brick into fine powder
Q:Whether the fire bricks are needed to be poured before construction?
Refractory bricks do not absorb water, do not need to water, what's more, refractory bricks need special refractory mortar to build. Refractory brick is used in the high temperature furnace, you won't use it to build walls.
Q:application of phosphate refractory bricks
The 4 properties of phosphate refractory bricks: (1) high strength wear resistance (2) and chemical erosion (its alkali resistant ability is better than that of clay brick and high alumina brick) (3) and good thermal shock resistance (4) high load softening temperature in rotary kiln, kilneye, kiln Zone door cover, cooling machine and lining refractory brick falling parts easy to loose
Q:What is refractory brick? What is refractory clay? ?
Refractory brick is a kind of brick that is fireproof, refractory soil is the soil that is fireproof
Q:Can lime rotary kiln refractory brick kiln be hung with klin coating?
Should prevent the rotary kiln from being damaged; why hang kiln coating on the rotary kiln; try to avoid the big knot; 5; maintain the integrity of flame shape; burn top fire; should be hung; to prolong the service life of the refractory brick; steel plate is unable to withstand the high temperature, strengthen calcination control; adjust the high temperature region; let the big block out in time; avoid burning the fire. . Preparation equipment manufacturers 4, find the correct operating parameters of rotary kiln according to the experience; often keep the temperature above 1450 DEG C in the container; what is the reason for the rotary kiln coating; and add a layer of strong protective layer on the surface; the cylinder of the rotary kiln cylinder is made of steel plate; this is only the first step to determine the safe operation of the rotary kiln; avoid damage or smash the rotary kiln coating. 2; measures should be taken to prevent the kiln coating fall off because of the stop of the kiln and the changing of sudden hotness and sudden cold; burn the top fire; raw materials of appropriate preparation ingredients . We need to know the the rotary kiln, make up in time. The fire resistance and thickness of refractory bricks are limited. 6; in the inside of the building with a layer of refractory brick. 8. Observe and adjust frequently; and can reduce the heat loss outward; control the fire; we take 8 steps to perfectly protect the rotary kiln: how to protect the kiln skin that is hung well; improve coal mouth structure; important operation method of long-term effective rate of safety energy-saving ball mill the work will be interrupted; deterioration, strengthen equipment maintenance of retary kiln, after hanging the rotary kiln skin; ensure clinker grain is fine and uniform; improve the thermal efficiency for the benefit of kiln skin sticking, must treat in time ;
Q:What refractory mortar is better if masonrying 4 meters height and 114 mm width of refractory brick
The selection of refractory mud should keep the principle of homogeneous phase with refractory bricks, that is to maintain the same material, according to the suitable temperature, choose appropriate binding agent compensation measuring forging Yao tic surprised boxing super man (phosphate, sodium silicate, or other organic combination), composite high performance admixture, it can be combined better in high temperature.
