A charging system for a shaft smelt reduction furnace includes a frame structure for mounting on a top charge opening of a shaft smelt reduction vessel; a center shaft arrangement supported by the frame structure and for removing off-gas gases from the furnace and to introduce granular charge materials to form a stack of materials in the furnace. The center shaft arrangement includes a center hood for off-gas extraction; a pair of first and second feed channels for first and second materials.

Dust emissions can be reduced in a metal or slag casting apparatus by providing an endless conveyor having a plurality of casting molds with upper open tops wherein the conveyor is arranged to move the casting molds in a first section from a casting station to a discharge station and in a second section back to the casting station. The method for reducing dust emissions includes (a) providing a casing forming a bottomless box over at least part of the first section of the conveyor, (b) injecting within the casing a gas on the surface of the mold with an angle configured to blow off loose, solid particles, formed at the surface of the metal, during early stages of the cooling down and to start the solidification of a superficial layer of metal or slag, and (c) extracting the gas and the solid particles by suction from within the casing.

A continuous casting mould comprises a mould tube (), a mould jacket () surrounding the mould tube (), a cooling system () within the mould jacket () for cooling the mould tube (), an oscillating lever () supporting the mould tube (). The oscillating lever () is capable of oscillating about a pivoting axis () substantially perpendicular to a casting plane containing the casting axis () for transmitting mechanical oscillations to the mould tube (). An oscillating mould cover () associated with the top end of the mould jacket (). The mould tube () is supported with its upper end by the oscillating mould cover (), and is itself pivotably supported by the oscillating lever () outside of the mould jacket (). A sealing element, e.g. an annular lip seal (), provides sealing between the oscillating mould cover () and the top end of the mould jacket ().
