Fireclay Brick with Al2O3 Content around 33%

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

Q: Why is the house made of refractory bricks not warm in winter: Heating equipment can be used

Q: What are the weak points of clay bricks?: Clay bricks are clay products with Al2O3 content of 30%~40% aluminum silicate material. Clay brick is made of 50% soft clay and 50% hard clay clinker, according to the requirements of a certain particle size. After molding and drying, the clay brick is burnt at high temperature 1300~1400 degrees celsius. The mineral composition of clay brick is mainly kaolinite (Al2O3, 2SiO2, 2H2O) and 6%~7% impurities (potassium, sodium, calcium, titanium, iron oxides). The sintering process of clay brick is mainly the process of the continuous dehydration of kaolinite and the formation of crystallization of mullite (3Al2O3. 2SiO2).

Q: In tunnel kiln, what is the meaning of refractory proportion 2.0?: That is the volume density of the refractory brick

Q: What is the problem about splintering when the refractory brick is fired?: There are many bubbles inside the refractory brick, it is also possible that the brick itself is not up to the standard about volume density, then refractory brick fragmentates. There are many reasons, may be in the process of repression

Q: What are the simple ways to distinguish between excessive clay bricks and less fired clay bricks?: Refers to the internal combustion brick to save raw material and fuel in clay mixed with waste parts containing combustibles, such as coal cinder, coal gangue and fly ash, and make the fuel burning in a brick in the baking process, so as to obtain uniform calcination temperature and combustion, called by this method of roasting brick brick.

Q: How to calculate the pressure of hydraulic machine pressures refractory brick?: If it is a plunger type cylinder, the pressure of a cylinder is the cross-sectional area of the piston multiplied by the pressure of the hydraulic system; if it is piston cylinder, that is the inner diameter of the hydraulic cylinder multiplied by the pressure of the hydraulic system. Adopt cm as diameter's unit, a unit of pressure is kilogram force per square centimeter, the calculated result is kilogram which divided by one thousand is ton.

Q: is there any requirement for radioactive materials in refractory materials.: they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value

Q: What is the main use of refractory brick?: Almost all high temperature furnace needs of the needs refractory bricks, such as blast furnace for iron smelting, high temperature differential thermal analyzer also use it, refining furnace, converter for steelmaking, muffle furnace, electric furnace and drying equipment. the uses are wide
