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:What are the sizes and sizes of clay bricks?

At present, with the minimum size of the maximum size of the market, for the maximum size of the clay brick, there are 600*250*200mm, 180*115*90mm, 300*300*55mm, and the minimum sizes 150*150*150mm, 235*115*55mm and so on, the construction industry the most basic materials for clay brick, must use in daily life is very broad.

Q:does Kyrgyzstan have the refractory brick to build tunnel kiln, whose specifications are 390,235,11, 240,120,60.

Domestic standard brick has no brick in this specification. only can be customised. Otherwise only have 230 * 65 * 114.

Q:What are the properties of clay bricks?

Clay brick is very important. It can make clay brick not only with high refractoriness, but also can be used in many high temperature thermal equipment. The brick brick has better resistance to hot and cold, and the water cooling can reach 10~25 times at 850 centigrade. Clay brick can resist weak acid slag corrosion, the resistance to alkaline slag is slightly worse, increasing the content of Al2O3, can improve the ability of alkali resistance slag.

Q:What is the specific heat of a refractory bricks (clay)?

Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG&#47, only elementary substance has specific heat refractoriness.

Q:can the refractory sand be used to make refractory bricks?

refractory bricks can be used as a refractory sand after crushing , no strength required results in the lower intensity, but the temperature is not high, so it is not recommended, but refractory bricks after the high temperature is fine because its properties are changed

Q:th choose of different refractory bricks in the rotary?kiln

According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy

Q:Will the heat be taken away by the refractory brick

The heat will be taken away by the refractory bricks.

Q:What are required for high temperature refractory bricks?

High temperature resistance, high pressure resistance

Q:What raw materials are used for refractory bricks

Phenolic resin, clay, powder and other materials, nitride materail, boron carbide, silicon carbide, silica raw material three, soil: fluorite, magnesia-alumina spinel Aluminum soil, calcium aluminate cement, corundum, andalusite, chlorite, silica solution, which is mainly divided into six categories, sillimanite, vermiculite refractory bricks raw material composition of refractory brick, there are many raw material kinds of refractory bricks, mullite, mine: Soil, Sialon, forsterite, pyrophyllite: Metal aluminium powder, ore, stone: Pottery, zircon sand, quinidine sulfate, dolomite, kaolin: The fifth raw material of chrome ore, sodium silicate, diatomaceous earth is the second raw material: Asphalt, sand, shale ceramisite. One of the raw materials, stone powder, the fourth raw material is magnesite, the sixth raw material is silicon metal powder refractory bricks, sand, kyanite, silica powder, aluminium oxide, aluminum sol, quartz sand, perlite, cenosphere, graphite
