Other refractory materials
In addition to the two in-house developments – Drache fused silica and fused silica fine –Drache also utilises other more refractory materials. The resulting use of manufactured components is also primarily in the Aluminium casting.
One such material is a SiC-based material. This is always used when very high abrasion resistance is required.
Another material is an Al2O3-based refractory material. Large components are generally made from this, which have very long contact times with the liquid Aluminium, such as liners for deep bed filters.
The production of special components with a refractory material specified by the customer is also possible on request.
