Head or slide plate for a molten-metal slide gate |
摘要 |
A head or slide plate for a molten-metal slide gate is formed by a refractory plate having an opening and a refractory ring positioned in the opening, with a ring of tar between the peripheries of the opening and refractory ring and which is isolated from the plate surfaces excepting for a passage filled with a porous refractory and through which the vaporized tar migrates to one of the slide surfaces when the plate and ring are heated by contact with the molten metal.
