Fireclay Brick
Fireclay brick is a kind of building material with high fire resistance. Its raw materials are mainly clay, lime, cement and gypsum, and different proportions of adjusting materials are added.
Features
1.High fire resistance
2.Acid and alkali resistance
3.Corrosion resistance
4.Good thermal resistance
5.Maintain a stable temperature in buildings
6.Resist the erosion of high temperature and hot air
Fireclay Brick Description
Fireclay bricks are weakly acidic refractory products, which can resist the erosion of acidic slag and acidic gas, but are slightly less resistant to alkaline substances.
In the temperature range of 0 to 1000 ° C, the volume of clay bricks expands uniformly with the increase of temperature. The linear expansion curve is approximately a straight line, and the linear expansion rate is 0.6% to 0.7%;
When the temperature reaches 1200°C and continues to rise, its volume will start to shrink from a larger expansion value.
The Application Of Fireclay Brick
Fireclay refractory bricks can effectively protect the internal structure of the metallurgical furnace and prevent the accumulation of heat, thereby improving the working efficiency of the metallurgical furnace.
Fireclay refractory bricks can effectively reduce the temperature in the coke oven, avoid burning in the coke oven, and prevent the interior of the coke oven from being corroded by air or other foreign objects.
Fireclay bricks are mainly used as the heat-resistant layer of the rotary kiln lining, which can ensure that the rotary kiln lining has sufficient mechanical strength and good thermal insulation performance.
Fireclay bricks are widely used in glass kilns, and can be used to decorate the interior and exterior walls of the sintering chamber of the glass kiln, as well as the roof, ground and vertical surfaces of the sintering chamber, etc.
Fireclay bricks can be used in lime kilns, mainly for the structure and heat insulation of kiln mouth, kiln, chimney and chimney flue, which can prevent the flame inside the lime kiln from spreading outward.
Fireclay bricks have good refractory properties, which can effectively prevent the transmission of thermal stress, protect the shell of the heating furnace, and prolong the service life of the heating furnace.
