Q:Why are the refractory bricks near to rotary kiln tyre easy to be short lives?
Q:Are refractory bricks poisonous?
Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive
Q:can castable refractory replace refractory bricks in rotary kiln?
No, there is expension gap between bricks, and that is no solution when the castable refractory expend.
Q:What are the advantages and disadvantages of clay refractory bricks?
Clay refractory bricks are clay products with Al2O3 content of 30%~40% aluminum silicate material. Solid clay refractory bricks are one of the oldest building materials in the world. They are from the Mausoleum of the First Qin Emperor in Shaanxi to Beijing and the Ming and Qing Dynasties in the Great Wall. It has inherited the history of architectural civilization of the Chinese nation for thousands of years. So far, it is still a popular building material. Fireclay brick materials, cheap, durable, fireproof, heat insulation, sound insulation, also absorb moisture and other advantages, is widely used in civil engineering.
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:What are the type, location and the physical and chemical effects of the refractory brick used in the cement rotary kiln?
But most people use high alumina brick or clay brick, G6 refractory brick. The specific masonry location, such as G4 refractory brick, standard brick, T38, OD, T39, according to the length of your rotary kiln, many kinds of refractory bricks are used in cement rotary kiln, the specific size of the inner diameter should be calculated in detail
Q:Is fireclay brick acidproof? Does clay brick anti corrosion when it's used to build chimney lining?
Refractory bricks anti acid and alkali after high-temperature calcination, and anti-corrosion won't be a problem
Q:Is the diameter of 2.5 meters of the calcium aluminate powder rotary kiln referred to the inner diameter of the refractory brick?
Perlite refractory brick is classified to outer diameter and inner diameter, pay attention to the accuracy of the size when measures, after drying, contains refractory. Our clay refractory bricks use 50% soft clay and 50% flint clay clinker, sodium to blend together according to a certain granularity requirements, after molding, etc., fireclay brick, 3373 in fact, there are many kinds of refractory bricks.
Q:What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?
It can't be the surface of coal, at least it is coal seed.
Q:buliding method of refractory bricks in boilers
