摘要： A sliding gate device for a vessel containing molten metal is disclosed. The device includes a stationary body (18, 20) defining an internal chamber (26) with an upstream wall and a downstream wall, each of said walls being provided with an opening, and said openings being opposite one another, as well as a sliding gate (28) movably mounted in said chamber and provided with at least one through-hole between its main surfaces. The sliding gate is guided by said chamber and a clearance is provided between the main sliding gate surfaces (28a, 28b) and the inner chamber wall. First and second means (40, 42) are provided for generating gas pressure in said chamber to provide a sealing gas flow between said sliding gate surfaces and the upstream and downstream chamber walls, whereby metal seepage is prevented. The first means (40) move the sliding gate in a first direction and the second means (42) move the sliding gate in the opposite direction.

摘要： Refractory materials including (A) 32-87 wt % of particles and/or grains of at least one refractory material having melting and thermal dissociation points higher than 1700 DEG C; (B) 7-50 wt % of a binding matrix formed in situ and consisting of a sialon, AlN or a polytype thereof, or a mixture thereof; (C) 2-20 wt % of a titanium nitride TiN material dispersed in the matrix; and optionally (D) 0-42 wt % of hexagonal boron nitride, amorphous carbon and/or crystallised graphite dispersed within the binding matrix. The materials are particularly useful in metallurgy.
