PURPOSE:To produce a cast slab having good quality by measuring reaction force acting to a mold from the cast slab in the assembling type mold at plural positions in the mold member and adjusting tapered degree of the mold member so that the reaction force comes to the suitable value. CONSTITUTION:The assembling type mold 30 is constituted by assembling plural mold members 10, and molten steel is poured into the mold 30 to execute contin uous casting. Then, measuring instruments 1, 2, 3 are set at one side of the mold member 10 to measure the reaction force from the cast slab 20 acting on cylinders 11, 12 with the measuring instruments 1, 2 and bending stress is measured with the measuring instrument 3, and each measured signal is inputted into an amplifier 31. Signal amplified in the amplifier 31 is inputted into a calculator 32 and based on the calculated result, a driving devices 21, 22 are driven, to adjust the mold members 10 so as to come to suitable tapered degree. By this method, the cast slab 20 having good quality in any steel kind and casting condition, is efficiently produced under stable operational condition.
