摘要： PURPOSE:To stabilize a discharging arc by providing a strip at right angles with a pass line of a material to be treated at positions in contact with electrode shields. CONSTITUTION:A strip 21 for vapor deposition of vapor molecules supplied continuously in the orthogonal direction with a pass line of a material 20 to be treated is set at a position in contact with or approaching to electrode shields 12, 13 directly above or below electrodes 10, 11 on both sides of the pass line continuously supplying the material 20 to be treated into a vacuum tank conducted to a vacuum system. Since this vapor deposition strip 21 is heated mainly by radiation heat based on discharge, it is water-cooled by rolls 22. Its position is adjusted by arms 25 to the electrode shields 12, 13 and bridle rolls 24 are arranged. In this way, vapor molecules accumulated on the electrode shields 12, 13 are removed continuously by a vacuum arc descaling device (e.g. brush rolls 23).

摘要： PURPOSE:To reduce the amt. of trimming and to improve the yield by detecting flaws on the surface of the material to be treated which is continuously fed, regulating the electric discharge mode of a divided unit electrode to set value and subjecting it to electric discharge machining. CONSTITUTION:A vacuum treating chamber 30 held to a vacuum of 1 to 10 Torr is oppositely equipped with electrodes 9 and conductor rolls 6 one after the other with the pass line of the strip 20 interposed. As for the electrodes 9, largely divided electrodes are arranged in a row in the breadwise direction of the strip 20, and the unit electrode is each provided with an electric discharge mode selectively. Furthermore, the electrodes 9 are provided in multistage rows in the breadwise direction of the strip 20. While the strip 20 is passed through, the flaws of the sheet are detected, e.g., by a noncontact flow detector 32, and the electric discharge mode of the unit electrode directly above or directly below the flaw parts among the electrodes 9 is previously regulated to set value by a controller 33. Then, oxides encroached on the defect parts are evaporated away by an electric discharge arc, and after that, crater parts removed by the electric discharge mode of the other unit electrode is fused, by which it is made smooth.

摘要： PURPOSE:To reduce the amt. of trimming and to improve the yield by detecting the edges of the material to be treated which is continuously fed, regulating the electric discharge mode of a divided unit electrode into set value and subjecting it to electric discharge machining. CONSTITUTION:A vacuum treating chamber 30 held to a vacuum of 1 to 10 Torr is opposite equipped with electrodes 9 and conductor rolls 6 one after the other with the pass line of the strip 20 interposed. As for the electrodes 9, largely divided electrodes are arranged in a row in the breadwise direction of the strip 20, and the unit electrode is each provided with an electric discharge mode selectively. While the strip 20 is passed through, the edges of the sheet are detected, e.g. by a photocell 32, and the electric discharge mode of the unit electrode directly above or directly below the edge parts of the sheet among the electrodes 9 is regulated to previously set value. Then, oxides encroached on the edges are evaporated away by an electric discharge arc, and after that, a crater part removed by the electric discharge mode of the other unit electrode is fused, by which the flaws of the edges are made harmless.

摘要： PURPOSE:To improve the surface roughness by providing anodes connected to a positive pole of a power supply for vacuum arc and cathodes consisting of a material to be treated in a vacuum chamber, attaching a noncontact sealing mechanism on the inlet side of the vacuum chamber and providing a mechanism for controlling thickness of the liquid which is applied on the surface of the material to be treated in the vacuum chamber. CONSTITUTION:Since a sealing mechanism 14 without contact with the material 13 to be treated is provided on the inlet side of the vacuum chamber 10 of a vacuum arc descaling device, the sealing effect of the vacuum chamber is attained without providing differential pressure sealing chambers on the inlet and outlet sides of the vacuum chamber. The liquid 12 and/or a viscous material are applied on the surface of the material 13 to be treated, so the liquid 12 in the vicinity of an arc spot is turned into vapor, an arc is moved toward the vapor and the moving speed of the arc spot is increased. That is, arc discharge in a vacuum generates arc columns more than the discharge in the air, the arc columns are turned into cathode spots (arc spots) on the surface of the material 13 to be treated and get about in search of scale. When the moving speed is increased, the arc spots can not locally stay on the cathode and local excess melting is eliminated.

摘要： PURPOSE:To make surface roughness fine by executing vacuum arc descaling by a magnetic field in which an arc is oscillated by acting an alternating field having the component of the line of magnetic force which is orthogonally crossed to an arc on the arc at the time of treating the surface of metal by discharging the vacuum arc on a material to be treated. CONSTITUTION:The anode electrodes 2 are provided as an electrode pair, the material 1 to be treated is connected to the cathode and a discharge arc is formed between the anode electrode 2 of the positive pole and the material 1 to be treated of the cathode. Arc shield plates 4-1, 4-2 are interposed between magnetic field generating coils 3-1, 3-2 provided on the anode. Since the magnetic field which is orthogonally crossed to an arc current is present, electromagnetic force acts on the arc in the direction of a vector product of the arc current and magnetic field and the arc is moved. Since the magnetic field is the alternating field, the force which acts on the arc is reversed at a timewise period and a reciprocating movement is inducted. The arc spot is moved, so the arc spot can not locally stay at the cathode on the material to be treated and deep molten pool is not made. In this way, local excess melting is prevented and the surface roughness is made fine and uniform.

摘要： PURPOSE:To save the energy cost by making the heat which is generated on a material by a vacuum arc discharge device a heat source or an auxiliary heat source for the heat treatment of the material to be worked. CONSTITUTION:The heat value generated on a material is calculated by a computer 10 from the actual value of the electric current and voltage which have been applied in arc descaling; the surface temperature of the material is measured and corrected; the result is deducted from the heat value required for a heat treatment; and the difference imparts an insufficient heat value to the material by an electric heat treatment equipment 9 through a controller 11. Since the arc heat generated for a vacuum arc descaling device 8 is utilized in the heat treatment equipment 9, the energy for the heat treatment is greatly saved. In addition, since it is performed in vacuum, the new production of oxide film is suppressed even after descaling.

摘要： PURPOSE:To vaporize off the impurities stuck to the surface of a metal as metallic waste without melting the metal by heating the cut waste above the vaporizing temp. of the impurities on the surface under reduced pressure. CONSTITUTION:A metallic waste consisting of galvanized steel sheet, etc., is cut into a desired shape, placed in a vacuum furnace 10 and agitated by an agitator 11, and the furnace is evacuated by a vacuum pump 16 and electrically heated 17. The values measured by a vacuum gage 12 and a thermometer 13 are inputted to a computer 21 to obtain the vaporizing temp. of the impurities such as zinc on the waste surface corresponding to the operating pressure and degree of vacuum through a converter 20, and the waste is heated to the obtained temp. or more under reduced pressure through a controller 22. Consequently, the impurites are vaporized and recovered in the trap 14 and filter 15 provided in an evacuating system.
