Abstract：By using the existing sinter technique, material and processing equipment, a new sintering technolgy is put forward in this project. It can achieve hybrid sintering on the sintering machine with an exthra-deep bed (1000mm) to enhance pelletization effect of basic materials,which is mixed with acid pellet before distributing on the sintering machine. Results show that after adopting the new technique, the material layer permeability improved significantly. The negative pressure of 1000mm material layer was only 985kPa which was better than 1209kPa of 600mm material layer was. Moreover, the permeability of adding 5—8mm pellets was significantly higher than adding >8mm pellets.When the amount of acid pellets was 40%, with wC=3.8%, 1200kPa vacuum sintering, the quality of the sinterwas the best.
