Abstract (en)
[origin: JPH01104462A] PURPOSE: To efficiently cool a fixed plate of a cooler for a ladle by a jet of a cooling fluid by providing an annular chamber partially enclosing an internal nozzle with a hollow member for supplying this fluid and forming many orifices facing the fixing plate of the cooler in the hollow members. CONSTITUTION: The wearing part 12B of the internal nozzle 12 is enclosed by the annular chamber 3 and envelopes the hollow member 5. The member 5 is communicated with a duct 6 for supplying a cooling fluid and is formed with many orifices 7 over the entire length of the member 5 so as to direct the jet of the cooling fluid to the fixed plate 22 enclosing a hole for casting. Then, the jet of the cooling fluid directed toward the fixed plate 22 powerfully cools the fixed plate.
