Q:How to distinguish the good or bad of the high aluminum brick?: In the procurement of high alumina brick, the first color, high quality aluminum brick, brick surface smooth, yellow color pale, four sides equal, no broken angle, no cracks.

Q:What are the characteristics of high alumina bricks?: High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining. High R.U.L, low creep high alumina brick with high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials.

Q:What is the standard classification of high alumina bricks and high alumina bricks?: Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.

Q:The difference between ordinary and diatomite brick refractory brick: Refractory brick belongs to a large class, according to different materials used are divided into: high alumina brick, dolomite brick, magnesia chrome brick, magnesia spinel brick, phosphate brick, carborundum brick, brick, mullite bricks etc..

Q:How are the grades of high alumina bricks differentiated?: In China, the content of Al2O3 in high alumina brick is usually divided into three categories: I, etc. - Al2O3 content > 75%; II, etc. - Al2O3 content is 60 to 75%; III and so on - Al2O3 content is 48 ~ 60%.

Q:What are the lining structures of lime rotary kilns and what are the requirements for refractories?: The current configuration of domestic calcining active lime rotary kiln refractories are as follows: the discharge end of low cement high alumina castable with 3% steel fiber; the cooling zone and the firing zone: dry magnesia spinel brick with high aluminum brick with high temperature; preheating: high alumina brick; low temperature preheating zone: clay brick light clay brick; feeding end: low cement high alumina castable with 3% steel fiber; in addition, brick size also have the corresponding requirements; dimensional tolerances: dimensional tolerances used in different parts of the requirements are not the same, the general control in 2mm; corner damage: general permit edge damage 40mm and 5mm deep within angle loss in the hot and cold surface is allowed to have only one, three edges and the length of not more than 50mm; there are cracks parallel to the use of surface crack is not allowed, cracks of brick surface are allowed.

Q:What are the categories of bricks?: Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.

Q:How much is one ton of high alumina refractory brick?: High alumina refractory brick according to the different content of AL2O3 is divided into grade, grade one and grade two, and grade three high aluminum brick, Zhengzhou Kang Hui refractories factory price in 800-1900 yuan / ton, stable quality, are exported to the domestic and foreign markets.

Q:Is glass wool inorganic thermal insulation material?: Yes, glass wool belongs to one kind of glass fiber. It is a kind of man-made inorganic fiber. Therefore, in the field of thermal insulation materials classified as inorganic insulation materials.

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.
