Increased wear mechanisms caused by liquid metal treatments such as desulphurisation and thermal shock conditions restricts the usage of traditional lining concepts. These treatments lead to higher temperatures, higher slag turbulances and higher chemical attacks. In order to provide higher service lifes, it is recommended to use ASC (Al2O3-SiC-C) bricks in torpedo ladles being no longer just a hot metal transfer car.
