| Abstract |
| At Rourkela Steel Plant, the life of steel ladle was low mainly due
to failure at bottom and slag zone and sometimes in metal zone.
For the improvement in life in key brick lining, design was made
in place of vartical brick lining. For the improvement in the life of
steel ladle bottom, AI 20 3-Mg0-C bricks (AMC) was developed
and for the improvement in metal zone, 75% Al 20 3 brick with
repetitive PLCR was tried. MgO-C bricks with superior properties
were used in slag zone. Around 40% improvement in ladle
life was achieved with a combination of design and the use of
superior quality refractories in different zones. |
