Quartz Sands in the Iron Processing and Refractory Industry

Due to its high purity Crystal Quartz Sand from Schlingmeier has a high thermal-mechanical stability. In general the sintering point exceeds 1.600°C. The high flowability of the sand results from the favourable particle shape which is subangular. Both high refractoriness and high flowability make it an outstanding basic material for the production of filler sands (sliding gate fillers) in steel mills.

The following table shows selected grades which are preferable used in the iron processing and refractory industry. All dry sands (T) can be supplied as blended grades. By adapting the particle size distribution significant parameters as flowability and packing density can be optimized. Please let us know your required grain size distribution.
