Process for the production and use of activated alumina in refining steel
TLDR
In this paper, an activated type alumina from aluminum dross by digestion with water, preferably pressurized, is described, where the peculiar properties associated with trace compounds present in the product make it useful for the recovery of noxious effluents from furnacing processes, including those burning fossil fuels and those used for smelting both aluminum and steel.Abstract:
Production of an activated type alumina from aluminum dross by digestion with water, preferably pressurized. The peculiar properties associated with trace compounds present in the product make it useful for the recovery of noxious effluents from furnacing processes, including those burning fossil fuels and those used for smelting both aluminum and steel, wherein the alumina beneficially incorporates in the metallurgical flux.read more

Patent
Slag forming agent for steel making
TL;DR: A slag forming agent for steel making which comprises 54 to 90 percent by weight of aluminium dross containing more than 30 percent of aluminium oxide, 5 to 20 percent of cement, 2 to 10 percent of calcium compound, 1 to 15 percent of chloride and small amount of water is described in this article.
Patent
Treatment of material removed from molten aluminum
TL;DR: In this paper, material such as is skimmed from the surface of molten aluminum in a casting furnace, which usually contains considerable aluminum metal along with chemical compounds such as alumina, is crushed and treated with dry steam at a moderately elevated temperature, so that unwanted carbides and nitrides are eliminated and the treated skim or the like is conditioned for recovery of useful values, advantageously by classification thereafter into a coarse fraction providing aluminum metal suitable for remelting and a fine fraction in which chemical material is reclaimed, that may include values suitable for use in the fused bath of
