Q:What is the best color of refractory brick
Clay refractory brick: Yellow and deep yellow; acid-proof brick: Red, high alumina brick Beige, a little white; square viewing brick: Yellow, red, white, gray, brown, brown, nigger-brown and so on; color is just one aspect of the selection of refractory bricks, it mainly is to see the inherent quality
Q:The matching ratio of masonrying refractory bricks cement
When building refractory bricks, use matching chamotte, do not use cement
Q:What is the coefficient of heat transfer for clay bricks?
The coefficient of heat transfer is called the total heat transfer coefficient. The current standards and specifications of the state are uniformly named as heat transfer coefficients. The heat transfer coefficient K value refers to the stable heat transfer condition, both sides of retaining structure air temperature is 1 degrees (K, c), 1s in the area of 1 square meters of the heat transfer unit, is w / (M2 - degree (W/) m - K, where K can replace c).
Q:How to choose refractory brick
According to the using environment of your product, process requirements, used place, refractory brick is very wide, there is low temperature, high temperature, there is heat insulation, there is wear resistant, corrosion resistance.
Q:Where are clay bricks or cement bricks?
Are clay bricks made of ordinary buildings or clay bricks on refractory materials?. Ordinary clay brick building is a burning clay made of red brick, (that is, the original old house with a little red brick) due to its extensive use of native resources and have great pollution in firing, now in some city has banned the use of the.
Q:Can mud and salt be used as refractory materials
Definitely not, the refractory temperature of soil just is more than 800 degrees, it belongs to eutectic mixture
Q:What is the clay used to make the refractory brick?
Lining brick of teeming ladle; refractory clay used in building materials industry to produce high alumina bricks for cement kilns and glass furnaces, as well as anti sliding, high alumina lining bricks and high alumina refractory clay. The hard clay in refractory clay is used for making blast furnace refractory material, which is used in agriculture as a fertilizer promoting agent and, and electron. High alumina clay is also used in the oil well, generally does not disperse in water. In metallurgy, accounts for 2/3 of abrasive products, and so on. Hard clay and semi hard clay can be used to manufacture daily-use ceramics. High alumina clay after calcination, which has high temperature resistance! Refractory clay refers to the degree of fire resistance is greater than 1580, the hardness and proportion is relatively big, the refractoriness is good. They except has relatively high refractoriness. Such as aluminum sulfate, its dosage accounts about 70% of all the refractory materials;
Q:What material is sk-34 on the refractory brick
Electric power; refractory bricks, castable refractory, building materials, chemical, glass, ferrous metals and other industries required refractory and insulation materials, all kinds of thermal insulation cotton products, thermal insulation brick, aluminous refractory cement, perlite and other unshaped refractory materials have been the best-selling products
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:General used refractory brick T-20 / T-39/ T-206 specifications and dimension
No T-206 model (we produce the clay) T-20 and T-39 are the size of 230*length, 113* width and 65/45 thickness, T-20 is a vertical arch brick and T-39 is horizontal arch brick.
