English term or phrase: Carryover slag

The extent to which oxidized carryover slag from the EAF can be tolerated in the ladle depends largely on the type and quality of steel produced. For exemple, for some grades of steel, such as rebar, the slag in the ladle plays a limited metallurgical role because of the fairly high P and S specifications of the steel. Here the carryover slag has an advantage as it provides the necessary slag volume required for arc-flare protection. A major benefit of utilizing and optimizing furnace carryover slag is that the carryover slag is already hot, and mostly liquid, so that it can act as a fluxing precursor, enhancing the dissolution kinetics of other flux additions. A suitable amount of lime is usually added to "neutralize" the slag to improve refractory compatibility. One of the primary concerns regarding slag carryover is the reversion of phosphorus for steel grades with very low P specifications. In these cases the carryover slag is either minimized during tap or removed after tap and a complete "synthetic" slag mixture is used.

carryover slag escória transferida

Explanation:
"Quando há passagem de escória, a condição mais normal, existem grandes dificuldades operacionais para quantificar corretamente a quantidade de escória transferida do FEA para a panela, mas, para isto, a primeira dificuldade é a medição desta quantidade.
Para contornar o problema da dificuldade de medição da quantidade de escória
transferida, criou-se um modelo de balanço de massa, focado..."
