Backfilling Mixes

The task of the refractory layer between wear lining and permanent lining is to prevent running behind and infiltrations. WEERULIN offers different backfilling mixes for this application - based either on alumina or on magnesia. They are easy to fill in by hand and bind only using the heat of the operation. Towards the fireside a ceramic protective layer develops and behind this the material keeps its insulating effect. When applied in layers of 40mm and more, the material can be left there and be reused.

Repair Mixes / Scrap Impact Zone

In some of the faster-wearing areas of the converter, running-down repair mixes prove efficient. They are simply poured from the Big Bag and start to flow under the heat, placing a refractory lining on the wear areas. Compared to gunning repairs they provide considerable advantages in saving time and improving lifespan.
