In a method for producing metallurgical molded coke by carbonizing lump coal produced by adding a binder to powdered coal with low caking property as a main component, the lump coal at room temperature is heated in a heating furnace. In the process of carbonizing the agglomerated coal, the surface layer of the agglomerated coal is rapidly coked by controlling the average heating rate until the center temperature of the agglomerated coal reaches 200℃ within the range of the following formula. A method for producing metallurgical molded coke, which is characterized by maintaining hot strength. 15℃/min/φ≦200℃−T B
