The patent describes an oscillating device for a continuous casting mould with a supporting structure (,), an oscillating lever (,), which has a forked first lever arm (,) and a second opposing lever arm (,), this oscillating lever (,) being mounted in the supporting structure by means of first swivel joints (,&Prime;) so as to be vibratable about an axis (,), and a stroke generator (,), which is connected to the second lever arm (,) of the oscillating lever (,). The oscillating device according to the invention comprises a supporting cage (,) for suspension of a continuous casting mould (,), this supporting cage (,) being connected via second swivel joints (,&Prime;) to the forked first lever arm (,) of the oscillating lever (,).

Continuous casting device

Ingot mould for continuous casting

An automated installation for lining a wall of an enclosure with brickwork is presented. This installation comprises a brick laying robot, a depalletizing module, a lifting module, a supply module and a centering ring module. At the level of the centering module which is installed on a working platform, a device for the sequential transfer of the bricks transfers the bricks into a centering position at the periphery of the working platform. In this centering position, the bricks are centered before the brick-laying robot comes to take them up.

Installation for lining an internal wall of an enclosure with brickwork

An apparatus is provided for supplying media to a blowing lance, particularly a blowing lance used in the production of steel by a top blowing process. A vertically movable lance carrier comprises a media connection device having a vertical connection surface. Before coupling, the blowing lance is first locked on the lance carrier by a fastening device. The connection device is movable horizontally in guide rails on the lance carrier from a waiting position towards the coupling head of the blowing lance.

Apparatus for supplying media to a blowing lance

The invention relates to a blowing lance suspension with integrated medium supply. In accordance with this invention, a U-shaped medium collector box having a horizontal top plate as carrier arm and a first connection surface is provided on the lance carriage. The medium connection pipes lead into this first connection surface. A lance carrier plate is provided, at right angles to the longitudinal axis of the lance, on the top part of the lance. The underside of the lance carrier plate forms a second connection surface into which the medium distributor pipes of the lance lead fittingly. After the lance has been laid down on the carrier arm of the lance carriage, the lance carrier plate is carried by the horizontal top plate, so that between the first and second connection surfaces, the connection of the medium pipes is made through the action of gravity.

Blowing lance suspension with integrated medium supply

Automated installation for the laying for masonry on a wall, especially of a converter, comprising an operating station with a work plateform movable vertically inside the enclosure and capable of rotating about the vertical axis of the latter, areas for the simultaneous storage of two pallets of bricks on the platform, a robot for handling and laying the bricks, a monitoring and control station, retractable props for stabilizing the operating station and a device for raising and lowering pallets of bricks. The entire operating station is supported by a telescopic mast mounted on a turntable of a movable floor which is located outside the enclosure and with which the operating station forms a retractable self-propelled or towable unit.

Automated bricklaying apparatus

An automatic lance changeover device is presented wherein a radially guided ring is axially vertically displaceable by two lifting spindle systems provided on each side of the ring and bears pivotable hooks for receiving the lance and for pressing the latter axially against a sealing surface on the coupling head. The hooks are connected to the stationary coupling head via pivotable connecting rods whose length is alterable, these connecting rods being eccentrically articulated on the support pin of the hooks with the bearing bore at the coupling head end of the connecting rods having a larger diameter than the associated wrist pin. When the ring is axially displaced, the hooks, which have swung out, in a first phase, initially surround the supporting pins on the upper part of the lance as the ring is displaced further, the hooks, without executing any further pivoting movement, pull the lance head into sealing contact with the coupling head.

An apparatus is presented for weighing heavy loads, particularly those loads having to be laterally supported during the weighing operation. The weighing apparatus comprises a vertical column supported on its base by pressure cells and provided on its top surface with a support structure. This support structure retains the material to be weighed. A guide tube is provided coaxially around the column and a rotating sleeve with bearing elements is mounted between the column and the guide tube. A motor is mounted on the guide tube for rotating the sleeve during the weighing operation. The weighing apparatus is particularly well suited for use in conjunction with a casting ladle used in revolving turrets during continuous casting.

Apparatus for weighing heavy loads

A rotatable drum, which bears beater bars and is intended for use in pulverizing metallurgical slag, is defined by abutting conduits which are welded to one another and to a tubular support. The arrays of conduits, through which a coolant is circulated, is interrupted at a number of locations spaced radially about the support where radially outwardly extending beater bars are welded to the same support. The beater bars are also provided with internal passages through which the coolant is circulated.
