ABSTRACT:
A hot metal gate for use in prefabricated hot metal runners takes the form of a prefabricated largely refractory unit that may be partially consumable and/or disintegratable when in contact with molten metal. The density of the material helps determine the known life of the hot metal gate when the same is exposed to molten metal in the hot metal runners. The gate is movably positioned by attachment to a lifting device.
