  • Tiltable arc furnace
    Patent number: 5054033
    Abstract: A tiltable arc furnace vessel is provided with a projecting, bay-like extension having a discharge opening closable from the outside only by a pivotable plate; the bay-like extension has a bottom substantially in the same level as the bottom of the remainder of the vessel. The vessel as a whole is titable by a hydraulic drive over a relatively small angle.

  • Device for nippling active electrode sections onto a combination electrode
    Patent number: 4518365
    Abstract: A device for nippling active electrode sections onto a combination electrode permanent upper section employing screw nipples to form the connection comprising an outer, essentially hollow cylindrical element and an inner hollow cylindrical element co-axially with in said outer element. The inner element is configured to couple with the connector element arranged on the upper end of the permanent section of said combination electrode. A drive is provided by means of which the inner element is rotatable in relation to the outer element around its axis.

  • Device for nippling up electrodes in an electric furance
    Patent number: 4484897
    Abstract: A device for the mechanical nippling up of electrode sections on an electrode positioned vertically in an electrode holder in an electric furnace, especially an arc furnace, by means of screw nipples forming the connection. The device comprises coaxial cylinders forming a coupling which can be coupled automatically or by control means with a connector element located on the upper end of the electrode section to be nippled up.

  • Process for the manufacture of steels with a high chromium content
    Patent number: 4001009
    Abstract: 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.
