摘要:
A belt for sealing a discharge device of a ferrous-metallurgical vessel is formed by two concentric grooves formed in one and/or the other of a pair of superimposed sliding plates. A first, outer, groove (8) is connected to a vacuum source and a second, inner, groove (1) is connected to an inert-gas source.
