Zusammenfassung:	1348861 Basic slagging material YOSHIZAWA LIME INDUSTRY CO Ltd 8 Feb 1972 [29 Nov 1971] 5723/72 Heading C1K A molten basic slagging material of formula 4CaO.Al 2 O 3 .Fe 2 O 3 is obtained by placing molten blast furnace slag in a ladle, blowing a fuel-air mixture into the ladle to heat the slag, and incorporating, per 100 parts of slag, 50-200 parts of Ca-containing material and 10-50 parts of Al-containing. material so as to desulphurize and increase the Ca and Al content of the slag. Quicklime, limestone, marl and/or slaked lime are specified Ca materials, whilst red mud, clay, alum shale and/or bauxite.
