摘要： PROBLEM TO BE SOLVED: To prevent formation of burrs at the both end parts of a cast slab and the ooze of molten steel from the lower ends of a pair of side weirs in conducting the continuous casting method of a twin drum type, where a thin cast strip is cast with the pair of side weirs being shifted upwards as pressed against both end-faces of a pair of drums.
SOLUTION: The formation of burrs is detected by measuring, with a plate- thickness gauge, the increase margins of plate-thickness at the width end-parts of a thin cast strip S discharged from the gap of drums 1, 1. The ooze of molten steel from the width end-part of the cast slab is detected by measuring the extension margin of width of the cast slab with a plate-width gauge 5 or by measuring the rise margins of temperature of the width end-parts of the cast slab. When the burrs are formed, the ascending speed of the side weirs 2 is increased and/or the pressing speed of the weirs 2 is decreased by a controller 7. When the molten steel oozes, the ascending speed of the weirs 2 is decreased and/or the pressing speed of the weirs 2 is increased.

摘要： PROBLEM TO BE SOLVED: To prevent the defective shape and the defective quality of a cast strip with a hot-line, in a twin-roll type strip continuous casting apparatus. SOLUTION: In the twin-roll type continuous casting facility for producing the thin-plate-like cast strip, the generation of the hot-line, is automatically sensed from the variation in temperature at the central part in the width direction of the cast strip just below the rolls. When the hot-line is generated, a roll reaction target value is automatically increased by a fixed value, and when the hot-line is completed, the reaction target value is automatically lowered to the original reaction target value and in this way, the defective shape and the defective quality of the cast strip with the hot-line can be prevented.
