Specifications

1.high refractoriness
2.low creep and liner change
3.stability in high tempreture
4.low heat conductivity , low bulk density

High alumia hollow ball refractory brick is one type of refractoy productions which has high alumina content above 84%, which insure the production high refractoriness and stability in high tempreture. While through special producing process and treatment, the micro hollow ball gives this prodution low bulk density and high porosity.

This type of high alumina refracory is widely used in many industries, such as the steel smelt industry/cemen manufacture industry/glass smelt industry/themoelecticty industry and so on. The refractoy production will help the enterpraises to reduce the pollution and energe exhaust,to supply a safer working enviroment to the employees.

1. Applicatons of the high alumina refractoy brick

The high alumina refracory brick is widely used and installed in different equipmnts, such as the steel blast furance/ hot blast airheater furnnce/glass kiln/cement kiln/lime kiln and so on.

Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?: Top burning type hot blast stoveIt means that the burner is installed on the top of the hot blast furnace of the iron making equipment, and it does not need a special combustion chamber in the vault space. It is also called a non combustion chamber type hot blast stove.

Q:Are there any differences between insulating bricks and refractory bricks?: The insulation performance of thermal conductivity of insulating brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better.

Q:What are the characteristics of high alumina bricks?: A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined.

Q:What are ordinary bricks, refractory bricks, hollow bricks?: Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material

Q:What is the standard classification of high alumina bricks and high alumina bricks?: High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. High alumina brick refractory clay brick and brick than refractoriness to high. It belongs to high refractory. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.According to the number of AL2O3 content is divided into, 55,65, 75,80 and so on several grades.

Q:Which is better, the soft core or the hard core?: The wire has two kinds of hard core and soft core, the hard core line is only one wire core, and the soft core line has a plurality of wire cores. For the same sectional area, the 7 core is more than the more than 30 core. There is a difference in use. Generally used for DC is the use of hard core line, because of its small line consumption; and for communication, we should use soft core line, but also in order to reduce its line consumption

Q:Is glass wool inorganic thermal insulation material?: The characteristics of glass wool, glass wool is the molten glass fibrosis, the formation of cotton like material, chemical composition of glass, is a kind of inorganic fibers. With good forming, small volume density, thermal conductivity, both thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.

Q:What is the price of the first grade high alumina brick?: The specifications and different prices, relatively large fluctuations of the main push of the refractory Dongxin high alumina brick high alumina brick prices generally around 3000 have various levels of Dongxin refractories

Q:Introduction of high alumina brick: Made from alumina or other raw materials of high alumina content; formed and calcined. High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining.

Q:What are the main components of high alumina bricks?: Sweat is like water mineral alumina bauxite, aluminum ore, magnesite, waves of gibbsite. Anhydrous alumina raw material, such as corundum, alumina, fused corundum. High alumina brick Zhengzhou gold company specializing in the production of various specifications, you can directly ask their technical staff.
