A rotary charging apparatus (RCA) has been in use on 1033-m3 at the Bhilai Metallurgical Plant (in India) since 1998. The RCA is a new type of charging apparatus in which the main working element is a five-vane revolving charge distributor that provides for multi-flow, multi-layered distribution of the charge materials in the top of the furnace. The revolving distributor makes it possible to flexibly and efficiently regulate the distribution of the materials over the entire radius of the top by changing the speed and direction of rotation of the rotor. The operational and design features of the RCA ensure a higher quality distribution of the materials in the top, which in turn leads to a significant savings of coke and an increase in furnace productivity. The total cost of maintaining and repairing the RCA is proving to be substantially lower than the corresponding costs for standard double-bell-and-hopper and chute-type charging apparatuses. The investment in the RCA is recovered in six months or less.
