Quick Sealing Devices

ONAK is a specialized manufacturer of quick sealing devices, products used in continuous casting in the steel cooling process.

QSDs are a customized solution placed inside the cooling chamber in order to cool the steel down with a safe and secure join.

They built a secure join between the cast steel and the dummy bar, helping in the cooling process of the steel and preventing leaks.

They avoid damage to the mould and handling operations risks (between tundish and mould), achieving the best guarantee and safety performance.
