Ladle nozzle

Scope and purpose

Ladle-nozzle – a type of refractory products used in the process of non-stop casting of steel. They are part of the components of refractories to a steel casting slide gate. They are an integral replaceable part of the nest block. Designed to form a jet of metal, are included in the connection with a refractory slide plate.
