Title:
溶銑の製造方法及び製造プラント
Document Type and Number:
Japanese Patent JP2013531733
Kind Code:
A
Abstract:
A process for producing hot metal includes partially reducing granular raw materials containing iron oxide with a carbonaceous reducing agent in a fluidized bed reactor at a temperature of at least 850° C. so as to obtain a reduced mixture. The reduced mixture is cooled to between 600° C. and 800° C. in a heat exchanger apparatus using a preheated process gas as a cooling medium that is preheated to between 300° C. and 500° C. before being introduced into the heat exchanger apparatus. The reduced mixture is then supplied to a smelting reduction unit via a discharge system.
