GRAPHITE-FIRECLAY STOPPERS AND NOZZLES

Graphite-fireclay stoppers and nozzles are refractory shaped products based on graphite and refractory grog with a ceramic bond used as a part of the closing system of casting ladles.

• graphite-fireclay stoppers and nozzles for less demanding ways of casting

• graphite-corundum stoppers and nozzles for casting high alloy and special steels with prolonged casting time

These products secures safe sealing of bottom pouring ladle opening, allowing safe repeated opening and careful draining of liquid metal. When bottom pouring ladle casting is used, there is no splashing of metal and therefore there is no oxygenation of cast metal. Using this system, a quality and purity of a metal is increased.
