Fireclay Material Nozzle Refractory Brick for Steel Industry
The Description:
The nozzle brick is a refractory molten steel flow outlet embedded in the base brick of the steel drum. When not pouring, the nozzle brick and plug head brick are in line contact to ensure that no steel leakage. The upper mouth of the brick is curved, which is easy to open and close the mouth and reduce the resistance of molten steel flow, and the lower part is a straight line section to stabilize the flow.
