Graphite sleeves
For rigid protection of coolers assemblies in non-ferrous upward continuous casting applications we propose our products obtained from clay bonded graphite materials.
Optimum wall thickness allows minimize heat fluxes penetration and prevent excessive heating of cooling media. Good material stability additionally makes it possible recurrent use of protection sleeves, cups and all the other products.
The typical properties values are as follows:
