- Q:What is the meaning of the new type of dry rotary kiln refractory brick 620,320?
- It should be the length of the turn. I'm not sure if it is right.
- Q:Which is the higher price of concrete solid brick and MU15 fired common brick (non clay brick)?
- The price of concrete solid bricks and the price of MU10 bricks are on the same level, and the difference will not exceed two cents a penny. It should be MU15 sinter ordinary brick is more expensive.
- 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: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.
- Dark red? Bright red? Orange red? 400,1100 or 1500 probably
- Q:What materials mix mortar to build walls (with bricks)? The more burned the harder
- Refractory mortar
- Q:the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
- The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
- Q:What are the reasons for the production of waste in the formation of fireclay bricks?
- The reasons for the production of waste when form fireclay bricks: Tile size is unqualified. This is due to the mold installation is not firm, the template transfers when molding; if the amount of material being added fluctuates largely, also can cause the body size changing. Ji Yangon Chi lie charge generation layer containing decyl poke pull and crack. The molding operation does not according to the principle of the light first and the thick later. At the initial pressure, the air doesn't releases, which causes the elastic aftereffect by repressing. Too much mud water, uneven mixture and inequal template all can make the body produce layer crack or crack. Twist. The template is used for too long, the template deforms, so raw brick deforms, the amount of water is too large, brick naturally deforms, causing the body twist. Miss edge and angle. Because of poor plasticity of mud, particles segregate, feeding back corner is not real, the body will appear side missing and angle modulation phenomenon. Bias voltage. Due to the deflection of the die head or the uneveness of mold bottom. Loose。 Due to insufficient feeding amount or insufficient pressure times.
- Q:What raw materials can be added to fireclay brick to respond to the urgent cold and urgent heat?
- The effect of adding andalusite is better
- Q:What are the properties of clay bricks?
- The clay brick belongs to weak acid refractory. Because of the fluctuation of chemical composition, the production method is different, and the difference of sintering temperature makes the properties of clay brick change greatly. Ordinary clay bricks are divided into (NZ) 1, 40, (NZ) 1, 35, (NZ) 1, 30, three trademarks on the basis of the amount of Al2O3 content in the components.
- Q:What are the weak points of clay bricks?
- In the temperature range of 0~1000 DEG C, the clay brick volume increases with temperature uniform expansion, linear expansion curve approximates a straight line, the line expansion rate is 0.6%~0.7%, about half of the brick. When the temperature reaches 1200 degrees Celsius and then continues to heat up, the volume will begin to shrink from the maximum expansion. The residual shrinkage of clay brick results in the cracking of masonry joints, which is a major drawback of clay bricks. When the temperature is above 1200 degrees, the low melting point of the clay brick gradually melts because the particles are very close to each other due to surface tension, resulting in volume shrinkage.
