제목 | Study on Reduction of Iron Scrap Immixed Waste Plastics as Porous Raw Materials for Steelmaking Process |
초록 | Plastic is mainly compound of carbon and hydrogen and may include other elements for its special use. Theoretically, almost all kinds of plastics can be used as reductive agent fuel in metallurgical process. Besides, the gasifying of waste plastics at high temperature inevitably forms porosities in the material that is more propitious to using it as a kind of raw material in steelmaking process. As the beforehand work, a group experiments were arranged to primarily determine the mixed gasifying gas compounds and to analyze the chemical compounds of the tar and semi-coke from the gasifying of waste plastics. Besides, a new way for using waste plastics in Direct Reduction Iron process was put forward in a project application to the National Natural Science Foundation of China in 2002. Since then, the reductive system of iron scrap that is a kind of porous gas-solid reaction has being been investigated by immixing waste plastics into the iron scrap reduction column. The experimental results show that inner reducing agents as well as good porosity in the reduction column by immixing waste plastics into the iron scrap profit systematic heat transfer, gas diffusion and interfacial chemical reaction. |
