Q:What are the main raw materials of refractory brick and runner brick?
Category of refractory , runner brick mainly is clay brick
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.
Q:What are the differences between diatomite brick and ordinary refractory bricks?
The volume density of diatomite brick is 3.9 * 10-6, good compressive strength, belongs to the small outer insulation, spinel brick.
Q:High alumina refractory bricks (Universal arc) weight for hot metal ladle
Climbing, C23B ladle generally use T3 ladle bottom brick, brick wall with C23 package, C231 Some permanent layers are built from high alumina bricks, and some are built from castable refractory, T82, T43. Specific size can be checked according to the type of brick
Q:How to increase the service life of high temperature refractory bricks?
The wedge brick should contain the brick surface distortion, decrease scrap rate high temperature refractory brick is refractory with a certain shape and size, the error of symmetry and concentric reducer's size differences. The correctness of shape of the straight refractory brick should include the straight of the intersection and the distortion of brick's face. Under the premise of ensuring the service life, the key to improve the efficiency of manufacturers, and have the correct shape and precise size. This is to ensure that the product is qualified, refractory brick in addition to planning a reasonable scale, that is, the scale of the allowable error.
Q:The boiler is divided into several categories according to the structure, what characteristics does each have?
package boiler and assemble boiler are divided into vertical boiler and horizontal boiler. Vertical boiler. Assembled boiler adapts to boiler more than 6 tons, the package adapts to boiler less than 10 tons.
Q:The difference between fireclay brick and refractory cilica brick in the application.
Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor
Q:Can refractory be used to sharpen knife?
Many factories build a smelting furnace by using this kind of bricks. A special knife grinder can be used to sharpen knife, can on 1. They are sizing and non-sizing refractory bricks respectively. Refractory brick is now a lot of fields and industry will introduce one of the raw materials. Products are divided into two different types, refractory brick as a high temperature resistance of the raw materials. In simple terms, working temperature is 770 DEG C, 580 C and 1, of course, refractory bricks also can be used to sharpen knife, use smooth brick to sharpen, need to choose high hardness
Q:several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
The life of refractory bricks in rotary kiln is generally short.
Q:Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?
There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.
