PURPOSE:To stabilize continuous casting operation by detecting variation component in the thickness direction of a strip and adjusting water film thickness at back face of belt mold based on the detected value with hydraulic cylinder. CONSTITUTION:Frames 2 for the mold are connected with plural pieces of tie rods 4 and detecting means 6 for stress or strain of the rod 4 is set in inner part of the rod 4. Further, at one side of end parts of the rod 4, the hydraulic cylinder 5 for controlling connecting load between the frames 2 is set. At the time of continuously casting, developed abnormal load is detected with the detecting means 6 and holding force between the frames 2 is found with a transducer 7 and the cylinder 5 is controlled with a relative operator 8 so as to become the presetted initial value. As water film breaking caused by forming of the abnormal cast strip is surely prevented, the continuous casting operation is stably executed. |
