Bath tapping system
Our bath tapping system can be used with forklifts or special vehicles and consists of a steel crucible with a cast iron lining. The cast iron lining is made in our PjN-G which is a proprietary alloy developed for increase lifetime. To use cast iron lining instead of traditional refractory material increases the lifetime with typical 2-3 times. Our bath tapping system also consist of a cast iron lid with no need for refractory material. Our cast iron lid provides a significantly higher lifetime compared with traditional steel lids with refractory material in addition to reduced OPEX.

The reference lid was a welded steel lid with refractory protection, it was also a very low distance between the surface of the liquid aluminium and the lid. Proven increase of lifetime from 12 to 18 months. The metal tapping system also consists of metal tapping tubes in various design and we have reached about 4500 tons of metal pr tapping tube.
