    摘要: Electrode for arc furnaces, more particularly for electrosteel production, also using scrap, comprising a detachable top portion (5) of metal and a replaceable bottom portion (6) of material which is consumed, where appropriate only slowly, having substantially cylindrical shape and being interconnected by a screw nipple (1) or the like and the top portion has a liquid cooling device with a header duct (2) and a return duct (3) and an inner part (16) and an outer part (17) of the top portion are constructed so as to be detachable from each other, so that the inner part (16) contains the liquid conducting chamber with header duct and return duct and the outer part (17) surrounds only a portion of the inner part (16). The electrodes have a reliable coolant conducting system, are easy to maintain and can be simply repaired in the event of mechanical damage while minimizing electrode down times.

    摘要: Electrodes for arc furnaces comprising a top portion (5) of metal and a replaceable bottom portion (6) of material which is only slowly consumable, being substantially cylindrical shape and the portions being interconnected by means of a screw nipple (1) or the like and the top portion has a liquid cooling device with a header duct (2) and a return duct (3) and the top portion (5) is advantageously protected in the bottom region thereof by means of an insulating coating of high temperature stability representing a detachably surmountable moulding. An electrically conductive intermediate layer of high temperature stability can be provided between the insulating moulding and the top portion. The electrodes are only slightly trouble prone, have emergency operating properties, have a high mechanical stressability and are easy to repair.

    摘要: An electrode for arc furnaces comprising a top portion of metal and a replaceable bottom portion of a material which, when appropriate, is only slowly consumed having a substantially cylindrical shape and being joined each to the other by a screwmounting, for example by means of a screw nipple or the like. The top portion includes a liquid cooling device or means with a header and a return duct, and an insulating coating of high temperature stability. An inner part and an outer part of the top portion are constructed so as to be detachable each from the other. The inner part extends substantially adjacent the screw nipple and at least a portion of the inner part is provided with an insulating coating of high temperature stability, which represents a loosely surmounted moulding.

    摘要: Post melting unit process for the decarbonization of stainless chromium steel containing at least about 10% chromium which comprises subjecting a melt of chromium containing steel at about 1580.degree.-1700.degree. C to a vacuum in the presence of sufficient oxygen to lower a starting carbon content which is above the ELC range into the ELC range, and simultaneously with subjection to vacuum, agitating the melt by gas purging, the heat added to the steel by combustion of carbon at least partially compensating for the heat loss due to post melting unit treatment.
