Zusammenfassung:	PROBLEM TO BE SOLVED: To decrease closure of a throat by designing a pour throat nozzle with a substantially cylindrical throat and substandially arched main body which communicates fluid by therewith in a round part. SOLUTION: A pore throat nozzle 20 is fitted in the a bottom part wall of a centrifugal device, and a molten slag can be transmitted thereby from the centrifugal device through a slag mold. Then, the pore throat nozzle 20 includes an arch profile 30, a nozzle throat wall 31, a taking-in orifice 32, and a taking-out orifice 33, and the pore throat nozzle 20 has an outside wall 34. Therefore, an exhaust stream 24 does not come into contact with the arch profile 30 at the time when the exhaust stream 24 passes through the inside thereof. Therefore, the nozzle 20 contributes to the prevention of build-up of the slag and closing of the throat.
