If the HP fraction is low, then HPs are well dispersed and, depending on sintering condition, soft particles can deform to fill all the gaps and complete densifiion can be reached. For a medium content of HPs, these.

    Another factor is that Fukuyama's No.5 sintering machine was modified in 1988 to a HPS (Hybrid Pellet ized Sintering) machine7) for producing highquality agglomerates using highquality fine ore pellet feed as the main material. Based on the characteristics of these two steelworks, total economic merits were pursued.
