ZEWA——处理钢铁工业废料以获得有价值产品的冶金新工艺

ZEWA——A New Metallurgical Process for the Treatment of Residues Primarily from the Steel Industry to Generate Valuable Products

ZEWA冶金新工艺将工业废料转化成铁水或矿物类产品如生产水泥用的水硬性胶结物、脱硫用冶金渣、铺路用材料等。工艺中包括专门设计的电加热反应器,用以进行高温熔融还原处理。一个包括所有必要的辅助设施在内的示范厂已在捷克共和国的Vítkovice钢厂建成,11次试验证实了利用碳钢和不锈钢生产的废料来生产铁水和有价值矿物类产品的技术和经济可行性。

ZEWA is a new metallurgical process which converts blends of industrial waste materials and residues into hot metal and mineral products such as hydraulic binders for cement production, metallurgical powders for desulphurization practices or materials suitable for road construction. The process involves high-temperature smelting-reduction operations which are carried out in a specially-designed, electrically-heated reactor. A demonstration plant with all necessary auxiliary facilities was erected at the Vitkovice Steelworks in the Czech Republic. In 11 test campaigns the technical and economical feasibility of the process with respect to the generation of hot metal and useful mineral products from the residues of carbon-and stainless-steel production could be proven.
