Contribution to characterization of the diatomite forindustrial application

Hazem MERADI, L’hadi ATOUI, Lynda BAHLOUL, kotbia LABIOD, Fadhel Ismail

Abstract: Diatomite also known Kieselguhr, is a non metallic mineral composed of the skeletal remains of microscopic single-celledaquatic algae called diatoms.The aim of this study was to test and to evaluate the diatomite of Sig region (West Algeria)tosubstitute the main mold powder used in continuous casting of steel for thermal insulation and lubrication. Generally, fluorineis added to mould fluxes to improve the viscosity. But this leads to the environmental pollution and the equipment corrosion. Thelaboratory and industrial investigations of diatomite have indicated the good results obtained in continuous casting of steel forthermal insulation and environmental protection against pollution (without fluorine). Also the characterization showed the hotbehavior of this product with the various transformations and could give the possibility to other use.

Keywords : diatomite, thermal insulation, lubrication, mold fluxes, fluorine
