Analiza żródeł emisji związków fluoru z procesów hutnictwa żelaza

Ferrous metallurgy has long been known as a major emitter of fluorine compounds. In the last few years,joint investigations into the problem of fluorine emissions have been carried out,special consideration being given to the fluorine content in the raw material made use of in metallyurgical processes, as well as to the guestion of how the raw material affects the guanitity of the fluorine compounds released into the atmosphere.In the present study,concentrations of fluorine compounds were measured in the raw materials used in ferrous metallurgy,in sintering ,ironmaking and steelmaking processes,as well as in the preparation of fusing agents.All the processes were found to be amongst the major sources contributing to the atmospheric concentrations and quantities of fluorine emitted in the form of gaseous and solid compounds ( including water-soluble species which are regarded as toxic ).
