Refractory Alumina Carbon Upper Nozzles for Ladle
Description
Ladle upper nozzle series are developed with newest matrix optimization technology and theory of most-compact.
In the pouring process, generally after pouring one or two furnaces of molten steel, the lower slide plate and the nozzle must be replaced and reassembled. The sealing protection adopts fibrous or mortar gaskets to ensure the high cleanliness of the molten steel and the uniformity of the internal quality of the casting slab.
The ladle nozzle is used to output the molten steel in the ladle. The ladle nozzle includes an upper nozzle, a sliding plate and a lower nozzle which are arranged in order from top to bottom. The sliding plate is slidable and the sliding plate is provided with molten steel holes.
