Direct Supply of Universal Arc and Refractory Bricks for Ladle Alumina Cement Fire Bricks

 The arc of the universal arc brick is semi-circular, and the other end is a groove. No matter the thickness, it will be flexible. Because he has no shaft, the size is slightly deviated, and the same can be made into a circle. So called universal arc, this brick is used in ladle.

The main applications of Superior Quality fireclay universal arc refractory brick as Lining Material are the high temperature parts such as blast furnaces and coke stove, waste incinerators and glass melting furnaces.

High aluminum brick is three oxide two aluminum (Al2O3) content is higher than 48% of the aluminum silicate refractory products.If the content of Al2O3 is higher than 90%, it is called corundum brick.Due to different resources, national standards are not completely consistent.For example, the lower limit of Al2O3 content for high alumina refractories in European countries is 42%.In China, according to the content of Al2O3 in high aluminum brick is usually divided into three classes :Ⅰ -Al2O3 content > 75%;Ⅱ et al --- the content of Al2O3 is 60 ~ 75%;Ⅲ et al ---the content of Al2O3 is 48 ~ 60%.A neutral refractory with an alumina content of more than 48%.It is formed and calcined from alumina or other raw materials with high alumina content.High thermal stability, refractoriness above 1770℃.Good slag resistance.Used for lining of electric steel-making furnace, glass furnace, cement rotary furnace, etc. 

Production process: the production process of high-alumina bricks and multi-clinker clay bricks is similar, the difference lies in the higher proportion of clinker in the ingredients, up to 90 ~ 95%, clinker before crushing needs to be sorted and screened to remove iron, sintering temperature is higher, such as Ⅰ, high alumina bricks with tunnel kiln firing is generally 1500 ~ 1600℃.
Application: It is mainly used for lining of blast furnace, hot blast furnace, top of electric furnace, blast furnace, reflection furnace and rotary kiln.In addition, high alumina brick is also widely used as open hearse regenerative lattice brick, plug head for gating system, nozzle brick, etc.But the price of high aluminum brick should be higher than clay brick, so the place that can satisfy the requirement with clay brick need not use high aluminum brick.

Detail the classification of high aluminum brick

1, ordinary high aluminum brick
The main mineral composition of the refractory brick is quartz, corundum and glass phase. With the increase of the content of Al2O3 in the product, mullite and corundum also increase, the glass phase will decrease accordingly, and the refractory and high temperature performance of the product will improve accordingly.Common high aluminum brick has a series of better fire resistance than clay brick, is a good application effect, widely used material, widely used in a variety of thermal kiln.Compared with clay brick, it can effectively improve the service life of kiln.
2, high charge soft high aluminum brick
Compared with ordinary high-alumina bricks, the difference between high-alumina bricks and high-alumina bricks is the matrix part and the binder part. In the matrix part, besides adding three-stone concentrate, according to the theoretical composition that the chemical composition after firing is close to mullite, the high-alumina materials, such as corundum powder and high-alumina corundum powder, are reasonably introduced.Binding agent selection of high quality ball clay, according to the variety of different clay composite binder, or mullite binder.By the above method, the load softening temperature of high aluminum brick can be increased by about 50~70℃.
