(과제) 특별한 설비 투자를 실시하지 않고, 고강도의 페로코크스용 성형물을 조업 트러블을 초래하지 않고 유리하게 제조할 수 있는 페로코크스용 성형물의 제조 방법을 제공한다. (해결 수단) 석탄, 철원 원료 및 연화점이 150 ℃ 이상인 고연화점 바인더 그리고 연화점이 150 ℃ 미만인 저연화점 바인더로 이루어지는 혼합 원료를 성형하여 페로코크스용 성형물을 제조하는 방법에 있어서, 상기 철원 원료 혹은 고연화점 바인더의 적어도 어느 일방을, 미리 고연화점 바인더의 연화점보다 20 ℃ 낮은 온도 이상의 온도로 가열한 후 혼합 성형한다. [Task] It is to propose a method for producing a molded product for ferrocoke, wherein a high-strength molded product for ferrocoke can be produced advantageously without making particular investment in facilities and inviting the operating troubles. [Solution] In a method for producing a molded product for ferrocoke by molding a mixed starting material of coal, an iron-source material, a high-softening point binder having a softening point of not lower than 150°C, and a low-softening point binder having a softening point of lower than 150°C, at least one of the iron-source material and the high-softening point binder is previously heated to not less than a temperature lower by 20°C than a softening point of the high-softening point binder to perform molding of the mixture.
