Method for producing hot briquette iron using high-temperature reduced iron and method and apparatus for controlling temperature of reduced iron for hot forming
Abstract:
Provided is a method for producing hot briquette iron by hot-forming high-temperature reduced iron reduced in a reducing furnace, involving cooling the high-temperature reduced iron and controlling the temperature of the reduced iron to an appropriate hot-forming temperature of over 600° C. and 750° C. or less, producing hot briquette iron by hot-forming the high-temperature reduced iron at an appropriate hot-forming temperature with a briquetting machine.
