We supply a broad range of extruded and vibration-molded specialty graphites for sheets and molds used in the production of melt-cast zirconium oxide refractory bricks. Even casting molds with complex geometries can be produced from our materials without problems. And our finished refractory bricks are of top quality – free of contaminants or surface imperfections. In addition, the casting molds produced from extruded and vibration-molded graphites can be reused several times, thanks to optimized oxidation properties.
In addition to our standard sizes, which we supply in lengths up to 3500 mm (138”), we also produce made-to-measure blocks tailored to the size requirements of our customers’ specific applications.
