PROBLEM TO BE SOLVED: To stably produce a cast metal by controlling drum reaction force based on molten steel temp. and molten steel height varied during casting, thereby preventing the occurrence of thickness variation and breakout of the cast metal. SOLUTION: In this method for producing the cast metal by a twin-drum type continuous casting machine having a pair of counter drums 1, 1' and side weirs pushed to both end surfaces thereof, the target drum reaction force value is corrected from the difference between a reference molten steel temp. and the actual molten steel temp. measured by a thermometer 5. Further, a molten steel static pressure value is calculated from the actual value of the molten steel surface height measured by a molten steel surface level meter 8 to correct the target drum reaction force, then the practical rolling reduction force applied on a solidified shell at a drum kissing point is calculated.
