Abstract: Simulating to the condition of iron powder production in Hoganas process, the reduction experiments of iron scrap were done by adding different kinds of typical chlorine free waste plastics in China into the scrap column. In this work, the influences of variety of waste plastics added and experiment temperature on the iron scrap reduction rates were studied by thermogravimetric analyses. Moreover, the remained pore canals made by the gasification of the waste plastics were investigated with microscopes. Furthermore, the effect of the remained pores in the column on the iron scrap reducing reaction between gas and solid phases was discussed.
Key words: Hoganas reduction, Waste plastics, Iron scrap, Remained pore
