Advances in ladle metallurgy control

The problem of slag depth is made more complex because slag thickness varies across the vessel depending on operating conditions In many plants slag thickness is measured using a steel rod The steel rod is immersed into the ladle until a portion has melted this point is judged to be the depth ofthe slag/metal interface 11 .
