FIELD: metallurgy. ^ SUBSTANCE: pellet manufacturing charge includes manganese raw material in the form of manganese concentrate, slag formation flux, reducing agent and binding agent. As binding agent, it contains slag as a result of melting of metal manganese, which is pre-crushed till specific surface area of 450-500 m2/kg in quantity of 7-14%. Water is added to the above charge, pellets are made and subject to hydration, and hardening and drying is performed at room temperature. ^ EFFECT: increasing mechanical strength of pellets, reducing the amount of moisture in pellets, decreasing the sintering temperature and reducing the consumption of carbonaceous materials. ^ 2 cl, 2 tbl, 1 ex |
