Abstract:
The present invention provides an isothermal processing method for making an isothermal processed copper clad aluminum composite comprising: providing an aluminum component and a copper component; cleaning the aluminum component and shape finishing the aluminum component; extruding the aluminum component into a core aluminum billet; cleaning the copper component; transforming the copper component into a copper cladding layer; cladding longitudinal and circumferential surfaces of the core aluminum billet with the copper cladding layer and molding the core aluminum billet and the copper cladding layer together to form a copper cladded aluminum billet; and transforming the copper cladded aluminum billet into an isothermal processed copper cladded aluminum composite through isothermal rolling and annealing. The present invention also provides an isothermal processed copper cladded aluminum composite and a system for manufacturing an isothermal processed copper cladded aluminum composite.
Abstract:
The descaling device (100) of the interior of a tube (1) comprises a supporting structure (9), a conveyor (2) for conveying the tube (1) with an inclinable stretch to arrange the tube in an inclined position by an angle with respect to the horizontal plane, a lance (3) with nozzles (4) to spray a fluid inside the tube (1) to carry out the operation of descaling the inner surface. The lance (3) is fixed to guides (7) above the conveyor (2) in an inclined position with respect to the horizontal plane, and may axially slide within the tube (1) during the descaling operation by spraying water into the tube.
Abstract:
A method and a device have high energy efficiency and high descaling performance, with which high-quality rolling stock can be produced. In a method in which the rolling stock is heated in an induction furnace and subsequently descaled, before the rolling stock is rolled in a rolling stand or rolling relay, the heated rolling stock is descaled by at least one rotating water jet from a rotary descaler; then at least one temperature of the descaled rolling stock is respectively recorded by a temperature measuring instrument and delivered to a controller; and the controller determines at least one control parameter with the aid of a control rule and by taking into account a setpoint temperature, and delivers it to a control component, at least one inductor of the induction furnace being driven so that the temperature of the descaled rolling stock corresponds as far as possible to the setpoint temperature.
Abstract:
The invention relates to an oil removing device for cleaning pipes that are present in the form of coils (13). Same device comprises a furnace that accommodates and heats the pipes, with or without associated cooling zone, and a gas guiding device (15, 16null) for feeding a scavenging gas to or removing it from the pipes. Said gas guiding device is provided with means for detachably and sealingly establish a link with a gas feed line and a gas discharge line. The aim of the invention is to configure the link with the pipes in as easy and reliable a manner as possible. For this purpose, the device is configured in such a manner that both ends of every pipe are separately connected to one and the same connecting head (4) that has a gas inlet (5) and a gas outlet opening the axially aligned therewith. The end (7) of the gas feed line and the end (8) of the gas discharge line are opposite each other and can be displaced along with the gas inlet opening and/or the gas outlet opening while sealingly connected.
Abstract:
A wire cleaning device using non-woven fibrous material rolls to wipe the surface of a wire to remove oil, dirt, and other contaminants. The device has a top feeder roller and a top receiving roller, and a complementary bottom feeder roller and receiving roller. The top and bottom rollers provide two sheets of material through which a wire is fed. The material sheets wipe the surface of the wire as it travels from the feeder roller to the receiving roller, providing a continually clean wiping surface.
Abstract:
A pipe coil is heated in the furnace of a heat treatment apparatus. The oil adhered to the inside of the pipe is vaporized by this heating. In this state the oil removing gas is fed at one end into the pipe which gas is in the high temperature enough to maintain the vaporizing condition of the oil. The vaporized oil within the pipe is discharged by the feeding of the gas at the other end of the pipe while the oil is in the vaporized state.
Abstract:
A die stem and a billet-receiving sleeve extend rearwardly from an extrusion apparatus platen slide that is movable laterally from a first position in which the stem is aligned with a billet container passage behind it to a second position in which the sleeve is aligned with the passage. An extrusion stem behind the container is movable forward through the passage, and there is means behind the sleeve in the first position for pushing a hot billet into the sleeve. A die slide carried by the container and holding a die is movable laterally across the container from an inner position aligned with the container passage when the platen slide is in its first position to an outer position aligned with the die stem in the second position of the platen slide. In the sleeve there is means for pushing a billet out of the sleeve in the second position of the platen slide and into the container as the container is moved forward toward the sleeve.
Abstract:
Metallic sheets, wires, bars or other products are descaled by sweeping their surfaces with one or more laser beams to detach an adhering oxide film along lines traced by the beam sweep. The film fragments, still loosely adhering at locations between the sweep lines, are then removed mechanically, chemically or electrolytically.
Abstract:
Apparatus for descaling wire. There is provided wet abrasive grit blasting means particularly adapted for descaling an elongated workpiece of generally rounded cross section, such as rod or wire. Said means contemplate placing at the discharge end of a generally conventional venturi tube into which a blasting slurry is introduced and through which the workpiece is coaxially led, one or more process means comprising serially connected chambers of repetitively varying cross section. In the illustrated embodiment each of said chambers includes a first portion of relatively large diameter, a second portion of converging diameter and a third portion of relatively small diameter. Same causes repeated slowing and acceleration of abrasive fluid flow together with repetitive expansion and contraction of the carrying gas, all of which generates a high degree of random turbulence and uniform action thereof onto the workpiece.
