摘要： A process and device are disclosed for melting scrap in a direct current-driven closed shaft furnace. The scrap is fed in a ring area at the furnace end, the hot gases which flow against the falling scrap are sucked below the scrap feeding area by the cylindrical outer wall of the scrap column, and the inner free surface of the ring-shaped flat cross section is reduced before the scrap reaches the melting zone. In the melting zone, the scrap is exposed to the electric arc at the center of the flat cross section. The arc furnace is designed in such a way that the cathode (21) is held by the electrode bearing device (30) designed as a concentrical pipe (31) with respect to the central axis (I) of the vessel. At its head end, the pipe (31) is conically tapered (34) and at its bottom end it is supported on the shaft (11) by bearing arms. A flue gas channel (19) which surrounds the shaft (11) is provided at the head of the shaft furnace (10).

摘要： A turn-lock fastener for the discharge hole at the bottom of a metallurgical vessel is characterised in that a discharge sleeve (3) with a slanted outlet channel (5) is set into the lower terminal section of a nose-ring block (1). A mirror-symmetrical sleeve (3a) to the discharge sleeve (3) has a complementary terminal surface (7a) which lies against the lower horizontal terminal surface (7) of the discharge sleeve (3). The sleeve (3a) is set into a spout (10) capable of rotating with respect to the fixed nose-ring block (1) about a vertical axis. In a determined position of rotation (open position) of the spout (10) the opposite openings of the outlet channels (5, 5a) in the sleeves (3, 3a) are aligned and in other positions of rotation (closing position) they are partially or completely separated from each other.

摘要： The invention relates to a process and device for blowing oxygen over a metal melt under a vacuum. The oxygen is to be applied over a large surface with a large intermediate phase area while avoiding overcooling in the metal bath by simple, easily maintained structural means. To this end the flow of oxygen in the lance is accelerated and compressed in pulses. The plug-shaped oxygen pulses leaving the lance in succession extend in a bell shape in the vacuum above the melt, with the cores of the oxygen bubbles moving at a similar speed to the casings. At the base of the wall (41) of the blowing lance (40) there is an annular nozzle (42). At a distance behind the annular nozzle (42) in the direction of flow of the oxygen there is a blind tube (44) forming a fan-shaped compartment (43). Between the bottom (46) of the blind tube (44) and the head of the blowing lance (40) there is a pre-nozzle chamber (48) and in the head of the blowing lance (40) there is at least one nozzle (50) directed towards the melt, whereby the nozzle (50) takes the form of a Laval nozzle and has components (51) to stabilise the flow of oxygen.

摘要： A process is disclosed for melting scrap metal. Threephase current is rectified to direct current by thyristors and is led through a cathode, through the material contained in a metallurgical vessel and through a bottom electrode designed as an anode. In order to actively influence the combustion by the electric arc and to attain the metallurgically highest possible power input by simple means, the power current is led through a group of at least two thyristors controlled by individually adjustable control currents; the negatively polarized power current is fed back to the melt by a common electrode and the positively polarized power current is independently fed back to the melt from the bottom of the vessel through at least two anodes.

摘要： The invention concerns a liquid-cooled adjustable-width plate mould for continuous casting of steel billets in slab form, in particular for slab thicknesses of less than 100 mm. The mould face plates (1) and edge plates (2) defining the form tend in their transverse direction to an increase in billet cross section, and the edge plates run substantially parallel to each other over the mould height. The face plates (1) are also concave in an area (3) corresponding to narrowest slab width so that, in cross-section, the crown point (13) of the mould wall forming an arc has a specific height with respect to an inscribed rectangle. The form of the mould plates at the delivery end (5) corresponds to the billet format being produced.

摘要： A device for indirectly heating fluids, in particular for high-temperature processes, comprises a heating space (14) containing at least one thermal radiator (1) and at least one planar serpentine pipe (4) through which the fluid to be heated flows and which can be heated externally by the radiant heat from the thermal radiator. To obtain a device for indirectly heating fluids in which the heat flux is distributed uniformly in the heat exchanger, each serpentine pipe (4) is associated with a pair of thermal radiators (1) which have a heat-radiating surface (3) shaped to match the planar extension of the serpentine pipe (4), the thermal radiators (1) are arranged on opposite sides of the serpentine pipe (4), and longitudinal ribs (5, 5a, 5b) are provided on the outside of the serpentine pipe (4) on opposide sides of the pipe cross-section. The longitudinal ribs (5, 5a, 5b) extend over the entire length or most of the length of the serpentine pipe (4) in the space between the coils of the serpentine pipe (4).

摘要： The invention relates to a fluid-cooled plasma burner with transferred arc in which the coolant, electric power and gas are taken via ignition and main electrode lances consisting of coaxial pipes to the ignition and main electrode. To improve the design of the burner, minimise heat losses from the burner jacket and improve the burner efficiency, it is proposed to provide a common coolant circuit (41, 35, 36, 43) for the ignition (16) and main electrode (27, 28) lances.

摘要： In a process for reducing the outer diameter and wall thickness of an essentially cylindrical hollow rough-pierced tube blank by rolling, the front end of the tube blank is introduced into a rolling mill. To prevent piping defects during rolling and to obviate other disadvantages of conventional processes, the diameter and/or the wall thickness of the end section of the rough-pierced tube blank is reduced before the end section is introduced into the reduction zone of the rolling mill.

摘要： The invention concerns a precision clamping unit for an injection moulding machine with a machine bed on which are arranged a fixed and a slidingly guided mould clamping plate, and at least a drive for moving and/or locking the mould clamping plate. In order to obtain a precision clamping unit for an injection moulding machine which, by the use of partly known features and measures, makes it possible to design a machine for precision injection moulding, the sliding mould clamping plate (2) is guided on a precision linear guide (8) mounted securely and in a torsion-resistant manner on the machine bed (7), and two parallel ball spindles (6) are arranged symmetrically in a horizontal plane on either side of the central axis (A) of the mould clamping plate (2) and driven synchronously by a motor (3). By means of the ball spindles (6), the movable mould clamping unit can be displaced and/or the clamping force applied. A hydraulic motor (3) which acts on the ball spindles (6) is provided to drive and/or lock the movable mould clamping plate (2).
