Abstract
PURPOSE: To raise the pressure-resisting strength and rotary wear-resisting strength of live pellets formed during the reductive baking operation in a rotary kiln by regulating the basicity of the live pellets within a specific range in the manufacture of pellets reduced by iron-containing dust generated in an iron works.
CONSTITUTION: An iron-containing dust generated in an iron works is mixed with a reducing agent, e.g., coke, coal, graphite powder, etc., a binder, e.g., bentonite, cement, etc., and a basicity regulator, e.g., lime powder, dolomite, etc., and then the mixture is further mixed with water and granulated to live pellets. Then the live pellets are dried, put with an external reducing agent into a rotary kiln, and then heated by a burner to manufacture reduced pellets. In this case, the basicity (CaO/ SiO2) of the live pellets is regulated to 1.0W1.6, whereby the strength of the live pellets is increased and the powdering of the pellets in the rotary kiln is prevented. Thus, a high quality of reduced pellets can be manufactured in high yield.
