Research Concerning the Obtaining From Industrial Wastes of a Cover Powder Used in Steel Continuous Casting


Article Preview

The paper presents research carried out in order to obtain thermo-isolating and covering powder used in the Tundish of the continuous casting installations. This powder is made by using different types of waste originating in the iron and steel industry and in the energy industry, such as: thermal power-station ashes, furnace slag, B.C.A. scraps, limestone, black ash, fluorine, raw dolomite, graphite powder. The powder thus obtained must have a faster melting speed and a lower melting temperature; it does not make the steel impure or diminish the heat losses through radiation. An effect of applying the experimental results in industry, besides financial economies, is to obtain an accelerated integration of a technological process in companies, according to European Union requirements regarding the preservation of the environment.
