Abstract: Tension bridles for a cold rolling reducing mill are provided. The reducing mill reduces the thickness of a metal strip passing through the reducing mill. The tension bridles create tension on the metal strip between the bridle and the first reducing stand to receive the metal strip and between the final reducing stand and the exit bridle so that a greater reduction can be made in the thickness of the metal strip in the first reducing stand and in the final reducing stand than is ordinarily possible. When the reducing mill is a reversible mill, a tension bridle positioned at each end of the mill enhances the reducing qualities of the mill and also enhances the quality of the metal strip being coiled after it passes through the mill.

Abstract: A pipe curtain is formed by a plurality of pipes independently suspended at one end portion to an outwardly extending flange positioned around a pollution control hood positioned at the discharge of a metallurgical furnace. Molten metal is transferred from the furnace to a metal transporting vessel through a trough, spout or the like. The hood is positioned above the trough and fans for the hood draw emissions, such as gaseous and particulate pollutants emitted from the molten metal, into the hood. The vertically suspended pipes are positioned in close relation to each other and substantially enclose the space between the bottom edge of the hood and the upper edge of the trough. With this arrangement the pipes form a curtain that prevents the air entrained pollutants emitted from the molten metal from escaping out from beneath the hood to the surrounding atmosphere.
