性能

Performance

阳极焙烧炉用高级粘土砖和红柱石砖。但红柱石砖明显优于粘土砖。这是因为其化学组成和矿物组成都非常适合该炉况,它具有良好的抗烟气Na2O侵蚀性。结构上红柱石更致密,有优良的抗CO性。

High-duty fireclay brick and andalusite brick for anode baking furnace. The andalusite brick is superior to fireclay brick obviously for the reason that its chemical composition and mineral composition are more suitable for furnace is characterized  by good Na2O fume resistant property, dense structure and good CO resistant performance  

红柱石砖有良好的抗热震稳定性和抗蠕变性,是焦炉炉们和高炉热风炉长寿化最优选的材料之一。

Andalusite brick is characterized by good thermal shock resistance and creep resistance, which is one of the optimized materials for open port of coke oven and furnace life of blast furnace hot-blast stove.  

硅线石砖致密,具有良好的抗热震稳定性,经常用在高温窑炉上,如玻璃窑炉等。

Sillimanite brick is characterized by dense structure and good thermal shock resistance, which is widely used in high temperature furnaces, such as glass melting furnace,etc.  

莫来石砖,具有良好的高温性能和优良的热震稳定性,常用于一些高温窑炉,如硫酸裂解炉和纤维玻璃窑等。

Mullite brick is characterized by good high-temperature resistance and good thermal shock resistance, which is widely used in high temperature furnaces, such as sulfuric cracking furnace and fibrous glass furnace,etc.  

莫来石刚玉砖有良好的高温使用性能,常用于还原炉或高温窑炉的内衬或烧咀。

Mullite corundum brick is characterized by good high temperance performance, which is commonly used in linings or high temperature furnace.

该砖具有良好的热震稳定性,特别适合操作不连续的窑炉。

this product is characterized by good thermal shock resistance, which is suitable for operation in discontinuous furnace in  particular
