Refractory brick classification for cement kiln

1, high aluminum brick: Al2O3 content more than 75, refractory degrees higher than clay brick, acid and alkali resistance erosion resistance, suitable for cement kiln etc., the use of long life and high price of refractory brick.
2, the dolomite brick: Hang kiln skin performance is good, good erosion resistance, but there are brick in f-CaO number, hydrated, difficult to transport and storage, production with less.
3, magnesia chrome brick: Hang kiln skin good, used for firing zone, the disadvantage is the thermal shock performance is poor, plus six price Cr is highly toxic, the production and use of magnesite chrome bricks in countries gradually reduced, now with this brick production unit as soon as possible to find alternatives.
4, spinel brick: mainly used for transition zone, earthquake good performance, anti good reducibility, but refractoriness slightly worse.
5, anti flaking brick: this brick contains a small amount of ZrO, martensite phase transformation occurred during the heating process of the formation of fine crack, with strong alkali resistance, spalling resistance and slag resistance of good.
6, phosphate brick: Refractory degree is low, but the intensity of heat shock resistance, used for refrigerating machine, such as the use of kiln hood.
7, silicon carbide brick: high temperature (1800 degrees, refractoriness under load in the 1620-1640), small thermal expansion coefficient, high thermal shock have good wear resistance suitable for cooling zone and kiln mouth.
8, the silicon mullite brick: thermal shock resistance, high strength, good wear resistance, suitable for transition zone.

Classification and application of mullite insulating bricks

    Mullite insulating brick is different according to the density is divided into light and heavy mullite brick, according to the use of different temperature are divided into: 1350 mullite bricks, 1450 mullite bricks, 1550 mullite bricks etc.

    Performance and application of mullite insulating brick:
    Refractory degree is high, can reach more than 1790 DEG C. Refractoriness under load was 1600 ~ 1700 DEG C. Compressive strength of 70 ~ 260MPa. Good thermal shock resistance. Sintered mullite brick and fused mullite brick two. Sintered mullite brick with high alumina bauxite clinker as the main raw material, adding a small amount of clay or raw bauxite as binder, after molding, sintering and made. Electric cast mullite brick with high alumina, A12O3 and refractory clay as raw material, adding charcoal or coke fines as a reducing agent, after forming by reduction of electric melting method to manufacture. Crystal fused mullite than sintered mullite, thermal shock resistance than sintered products. Uniformity of content in the high temperature properties of alumina and mullite mainly depends on their distribution and glass. Mainly used for blast furnace hot blast stove top, bottom, and glass furnace regenerator, ceramic sintering furnace, petroleum cracking system dead lining.

Ladle Permeable Brick,Refractory Brick

Ladle Permeable Brick

Ladle permeable brick has been in the leading position in domestic and abroad over years. We have developed the series of corundum, chromium corundum, low silicon chromium corundum and corundum spinel one after another. They can be designed and produced types of straight hole, directional slit, directional labyrinth, girth shape and interior and exterior integral split etc according to users’ request.  Permeable flow rate of products can be designed upon customers’ request and can be adjusted in a wide range. The blowing opening rate is high.

High Alumina EPS Insulating Firebrick,High Alumina Brick,Insulating Brick,Refractory Brick,Firebrick,High Alumina Insulating Brick

This king of products is sintered mainly with supper-fine bauxite charlotte and proper additive by a method of EPS ignition loss. Their main advantages include high intensity, low thermal conductivity, excellent thermal stability, very small reheat linear change, outstands erosion and corrosion resistance etc. They are an ideal kind of energy conserving products, which can be widely used as lining or insulating brick layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry, chemical industry, etc. Recommended to use below 1400℃.
