Based on simulating molten steel by water,simulating scrap steels with water and hollow plastic balls mixed with ice cakes,the physical simulation method was used to study the ef-fects of different exterior shapes and sizes of scrap-steel-packaging blocks on the homogenizing time of molten steel bath in converter during smelting by the 260 t converter. And thus the melting process of those scrap steels was in state of the visualization and further the effect of scrap-steel-packing block shapes on melting of scrap steels and homogenizing time of molten steel bath in converter were determined. So the experiment results showed that the homogenizing time of molten steel bath in converter lengthened significantly after adding scrap-steel-packing blocks to the bath,while the homogenizing time lessened gradually as the melting of these scrap steels. There-fore,while adding scrap-steel-packing blocks with the same total weight and different specifica-tions,the closer the exterior shapes were to the cube,the relatively shorter the time of smelting by converter was,which was more beneficial to steel-making production.
