Embodiment Construction

[0027] figure 1 In , an embodiment of a device 1 according to the invention is schematically shown, which is particularly suitable for the treatment of continuous - eg wires, rods, pipes etc. - material 8 . The continuous material enters the heating chamber 3 through the gate 2, and the material is heated to at least 100°C by the heating device 9 when passing through the heating chamber 4, so that most of the pollutants on the surface of the material 8, such as scale, are peeled off due to heating . A pressure P1 of between 0.1 and 10 mbar is generated in the heating chamber 3 by a vacuum pump 11 . In this embodiment, the heating chamber 3 has a coaxial geometry, wherein the heating device 9 is a plasma heater with an external electrode as an anode, which is arranged in the heating chamber 3 and is covered with a continuous material. The continuous material 8 forms an internal electrode, which is brought to zero potential via conductive rollers 12, 12' and thus serves as a c...

Abstract

The invention relates to a method and a device (1) for the treatment of materials, in particular endless materials, such as wires, rods, tubes, etc. The device comprises a heating chamber (3) for heating fed material (8) during its movement through the heating chamber (3) and a plasma reactor (5) which is arranged upstream of the heating chamber and has at least one discharge chamber (10), through which the material (8) can be transported continuously and in which the material can be subjected to a plasma treatment while it is moving through.

Description

technical field [0001] The present invention relates to a method and a device for processing material, especially continuous material such as wire, rod, pipe or the like. Background technique [0002] In many production processes materials such as wires, rods, tubes etc. are used. These materials can be transported to designated locations as semi-finished or finished products and processed further during the production process, or they can be directly manufactured and further processed during a certain production process. The problem that almost always arises during processing is that the material is always covered with a layer of impurities and thus cannot be processed directly. Its surface has at least one natural oxide layer. More often, the material is also contaminated with different organic and inorganic impurities. Organic impurities are usually residues of oils or fats used in processing. Inorganic impurities include oxides, chlorides and sulfides. The thickness...
