PROCESS FOR UTILIZING ALUMINIUM-CONTAINING SLAG FOR THE PRODUCTION OF CALORIFIC AND THERMAL EQUILIBRUM REGULATING MIXTURES

摘要

Ground powdered slags from aluminium prodn. comprising (%w/w) 5-70 Al, 15-60 Al2O3, 3-5 Si, 5-15 SiO2, 0.5-5 Fe2O3, 0-5 MgO are mixed with up to 60 of perlite or sand to produce a heat insulator which can be used, for example, in ingot mould riser insulation.
