Abstract: An installation for rolling a metal strip includes a rolling mill through which the strip is rolled as it passes continuously, rolling agents brought into contact with rolls of the rolling mill and with the strip, a strip drawing unit positioned at the outlet of the rolling mill, and a decontamination module with at least one degreaser positioned between the outlet of the rolling mill and the drawing unit so as to remove residual rolling agents from the strip at the outlet from the rolling mill. A strip accumulator is positioned at the outlet of at least part of the drawing unit, particularly so as to keep the speed of travel of the strip at the outlet of the accumulator below a maximum threshold. A paper-strip insertion module is positioned downstream of the outlet from the strip accumulator.

Abstract: A disassembly apparatus and a method for changing at least one cylinder and/or a cluster of a laterally supported 6-high roll stand. The disassembly apparatus includes: a handling frame, including a positioning and moving device for moving and positioning same; a mobile shuttle capable of moving over the frame, wherein the shuttle includes an extraction device which can be moved by a moving member and which can disassemble the roll stand or assemble a cluster and/or a lateral supporting cylinder on it. The extraction device includes an upper crossbeam rigidly connected, via a movable strut, to a lower crossbeam. Each of the crossbeams have, at each of their ends, a movable gripping plate including at least one locking bolt. The gripping plates of a single crossbeam are configured to grip at least one cluster and/or at least one lateral supporting cylinder by actuating the locking bolt.

Abstract: A roll stand has two working rollers capable of gripping a strip to be rolled, two intermediate rollers, two bearing rollers, and at least one side bearing unit capable of laterally supporting the working rollers. At least one camber block for cambering the intermediate rollers is capable of vertical movement relative to the posts of the roll stand and of supporting the side bearing unit.

Abstract: The invention relates to a plug device for a standard electrical connection cord provided with a cord plug that includes an external mechanical latch having a control lever. The device comprises a plug body; a plug adapter that can be fastened inside the plug body; a packing body including packing; and a link part having a first end for connection with the plug body and a second end for connection with the packing body. The plug adapter has an internal profile suitable for receiving the body of the cord plug and having fastening means for retaining the cord plug body and for holding said latch of the cord plug body in its inactive position.

Abstract: A process for producing a foaming slag above a stainless steel melted in an electric furnace, in which: a powder containing at least one metal oxide and carbon in its composition is introduced into the slag, at least one oxide present in the powder is reduced by its reaction with the carbon to form in the slag bubbles composed of the metal of the metal oxide and of carbon monoxide, the bubbles present in the slag giving rise to a slag in the form of a stable foam.

Abstract: A 6-high cold rolling mill. The mill is of the type having free floating, side-supported upper and lower work rolls, chock mounted upper and lower intermediate rolls and upper and lower back up rolls. Vertically acting hydraulic cylinders are provided for intermediate roll balancing, bending, counterbalancing and vertically shifting the upper and lower intermediate rolls toward and away from each other. Horizontal cylinders provide axial shifting of the intermediate rolls and two cylinder actuated supports are provided to lift the upper work roll. All of these cylinders are mounted on the mill housing and no hydraulic disconnection and reconnection is required for replacement of the intermediate rolls and/or the work rolls. Each intermediate roll assembly supports between its chocks a pair of side support assemblies for the work rolls.
