Refractory dart

タイトルまたは説明

Slag darts are refractory shapes that are used during the production of steel in the basic oxygen furnace (BOF) process. They are designed to float at the interface between the liquid steel and slag in the furnace and minimise the amount of slag that is carried over to the ladle during the tapping process. The slag dart is inserted mechanically into the taphole toward the end of the tapping operation. When the steel is drained from the furnace it seals the taphole thus holding back the slag. Slag is an undesirable element that will lead to impurities and a subsequent reduction in steel quality.
