Provided are a method and an apparatus for agglomerating direct-reduced iron which are capable of efficiently removing gas existing in direct-reduced iron, and an apparatus for manufacturing molten iron including the same. A method of agglomerating direct-reduced iron includes: i) filling a space in reduced iron with one or more gases selected from a group consisting of carbon monoxide and carbon dioxide; and ii) converting the carbon monoxide into carbon dioxide and carbon while agglomerating the reduced iron.

Provided is a cheek plate for an apparatus for agglomerating reduced iron, the cheek plate including: a cover portion which has a fan shape and is installed at each of both sides of a pair of rollers for processing the reduced iron to prevent the reduced iron from leaking to a lateral space formed between the rollers; roller close contact portions which protrude from inner rim portions of the cover portion and are in close contact with outer portions of the rollers to maintain airtightness of the space between the rollers; and gas discharge portions which extend along plate surfaces of the roller close contact portions, and discharge gas produced when processing the reduced iron, thereby effectively discharging gas produced when processing the reduced iron while increasing close contact force between the cheek plates and both sides of the rollers.
摘要:
The present invention relates to a method and device for removing dust particles from reducing gas. The method of the present invention comprises a step of providing reducing gas, a step of injecting the reducing gas into a chamber including a sacrificial nozzle therein, and a step of discharging the reducing gas from the chamber. According to the present invention, since low-melting alkali chloride contained in the reducing gas is removed before being blown into a fluidized reducing furnace, the operation rate of the fluidized reducing furnace is improved due to the reduced clogging of the distribution nozzle in the fluidized reducing furnace, and the ore reduction rate is increased and fuel costs are reduced as the temperature of the reducing gas is increased.
