电炉圆心底出钢(RBT)用耐火材料

Refractories for round bottom tapping（RBT）of EAF

分析了电炉圆心底出钢（RBT）的使用环境，认为RBT袖砖应选用优质镁炭等静压成型整体内芯或铝锆炭复合等静压制品，RBT用不定形耐火材料趋向功能化方向发展。

It is considered that MgO－C、Al2O3－ZrO2－C isostatic pressed composite products should be selected for RBT assleeve brick and the unshaped material for RBT should be deveoped toward functionization.
