$Refractory Fireclay Brick with Al2O3 Content around 31%$

Q: Lining of refractory bricks in rotary furnace: The lining of the converter is probably a furnace, but if it is changed at least to see the material and the use of it. There are a lot of damage to the lining, such as: The total impurity content reduces to 2%, lining life will increase 20%-40%; CAO in brick is of 60%-80% content , lining life are the highest; also some other proper index can not be ignored such as bulk density,heat/thermal shock resistant performance,porosity,thermal expansion,fracture resistace,volume stability,Slag resistance,and so on. In addition, lining erosion rate is the largest when the basicity of slag is 1, with the increase of basicity, erosion rate decrease rapidly, the temperature can cause cracks spalling of lining. At the same time, the building process is also very important.

Q: what effect does big mortar joints of the boiler refractory brick have on the boiler?: The ventilation leakage。 Now the larger boilers are generally used refractory pouring material one-time pouring, the arch is easy to collapse . 2, shrinkage and expansion of brick will make the bricks fall. 1, do not use the refractory brick. too large seam will effect the tightness of furnace wall , and the water wall is easy to form dew and be corroded and to leak smoke.

Q: Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?: refractory castable integrally casting

Q: Do refractory bricks need to be sent to the lab to test after arriving the site?: Generally speaking, as long as the use of temperature is not higher than 1500 degrees, it is not required to do the test, even if the ordinary refractory brick temperature is about 1500. If the temperature is high, then you do test to determine what kind of texture of refractory brick you need

Q: How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.: If the raw materials are different, then the redness is different under different temperatures.

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: Why masonry walls must not be mixed with clay bricks?: If a masonry wall is added to the concrete structure. Under the influence of lateral force (wind force, earthquake force), the performance of masonry wall and concrete wall is different, the former is rigid and almost unable to bear deformation, while the latter can have certain deformation. The former cannot bend and the latter can bend...... As a result, the masonry walls were destroyed first and lost, and then the members supported by the masonry walls were destroyed, and the whole building was filled with cups.

Q: What is the advantage of the ceramic fiber material compared with the refractory brick?: Ceramic fiber material is heavier than refractory bricks, property of machinery operation, low heat capacity, and has high anti-stretchability and good thermal shock resistance, low thermal conductivity make its thermal insulation effect is ten times than refractory brick, it won't has crack in sudden coolness and heat, and the construction is much easier than that of refractory brick, not delaying the production.

Q: What are the differences between fired brick and clay brick?: You can refer to see Yixing Dingcheng ceramic clay brick, clay brick is their production of professional manufacturers, quality assurance, the price is high

Q: Can refractory bricks be used to build a house?: Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
