BG 6# blastfurnace bosh area had been broken out , the bosh inner used the high thermal conduction and plumbago carbon brick replace the micropore carbon brick, and the results are obviously better.
本钢6#高炉炉腹区域烧穿，炉腹内衬采用高导热、高体密石墨碳砖代替原烧成微孔铝碳砖，实施效果良好。

The carbon brick before using and after using in blastfurnace has been analysed at lab in this paper. The permeability and pore diameter distribution of carbon brick has been measured respectively.
The viscosity and crystallizability of basalt melt and the other two samples, which are composed of a certain amount of brick and of blastfurnace slag respectively, are studied experimentally.
