Experimental study on the preparation of ultrafine zinc powder by hot-dip galvanizing slag |
| |
| Abstract: | The hot galvanizing slag from cold rolling mill was used as raw materials,ultrafine zinc powder was prepared by evaporation condensation method. Using new evaporation device and cooling device,effects of maxi-mum evaporation temperature,temperature holding time,protective gas quantity,evaporation materials and cool-ing intensity on the yield of zinc powder and particle size distribution were studied. The resulting particle size dis-tribution,chemical composition,XRD and microstructure of the ultrafine zinc powder were tested,and the causes and countermeasures of zinc powder conglobation were discussed. |
