<p><P>PROBLEM TO BE SOLVED: To provide a novel method for efficiently producing ferro coke considering improvement of a molding yield in a molding process for agglomeration of raw materials. <P>SOLUTION: When ferro coke is produced by carbonizing a molded material prepared by molding a molding raw material containing coal 20, an iron source raw material 21 and a binder, the molded material after molding is sieved by a sieve 3 to separate a ferro coke producing molded material and a powder portion from each other, and the ferro coke producing molded material is carbonized by a carbonization furnace 4, while the powder portion is conveyed by a powder portion conveying line 7 to be used as the molding raw material of the molded material. Preferably, the grain size of the powder portion is 6 mm or less, 3-15 mass% of the powder portion is used as the molding raw material based on the total amount of the coal and the iron source raw material, and the molded material is molded by using a double-roll molding machine 2. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
