抄録
The softening behavior under load was investigated using cold bonded pellets with cement binders, made from iron ores of several types.<BR>In the case of cold bonded pellets, both the swelling and softening by reduction at elevating temperatures resulted in a big pressure drop in the softening test.<BR>The prevention of the swelling was effective when iron-silicate of low melting point was made from wustite and gangue minerals in a pellet particle in the temperature range from 900 to 1 100°C at which swelling usually took place to form slag net works.<BR>For the prevention of the softening, it was essential that the melting point of gangue minerals was transformed to higher levels.<BR>To satisfy both the requirements, iron-silicate of low melting point, bearing CaO, must be made in the temperature range from 900 to 1 100°C and transformed to Ca-silicate of high melting points by reduction above 1100°C.<BR>As the suitable composition of the cold bonded pellet including binders to meet the restriction, its gangue amount must be higher than 220 kg/t-Fe and its basicity (CaO/SiO) more than 1.2.
