Abstract
A door opening/closing device of door-type rotary nozzle which cannot fit collector nozzle (16) unless clampers are removed. There is no possibility of pouring molten metal while forgetting to remove the clampers (25). When the fixed frame (7) is opened or closed, a ladle is fitted by a 90 degree angle with its bottom almost vertical. So, the fitting and removing operations of the clampers (25) can be performed in front of an operator, which makes the operation very easy.
