摘要： A highly flexible sealing arrangement designed to seal high-temperature furnace ports, particularly the electrode port of an electric furnace. The seal comprises an annular support member fixed to a flexible sealing member and employs the use of a garter spring to uniformly apply the desired amount of seal compression. The arrangement and flexibility of the sealing member allows the seal to adapt itself to the wide range of operating and upset conditions that typically exist for a furnace electrode seal. Frictional wear on the seal may be greatly reduced as the design inherently allows for a much lower amount of seal compression to be applied, furthermore, the seal is able to move axially which can significantly reduce wear caused by electrode regulation.

摘要： The present invention provides a graphite electrode for an electric arc furnace used for steelmaking which can effectively suppress oxidation and consumption of the graphite electrode used for an electric steelmaking furnace during the operation and reduce the electrode consumption rate. The graphite electrode is used for an electric steelmaking furnace which is operated while cooling the graphite electrode which protrudes upward from the furnace roof by spraying a cooling liquid onto the surface of the graphite electrode, wherein an uneven surface structure is formed on the surface of the graphite electrode.

摘要： Described is a system designed to warm the transfer chamber used in vacuum equipment in the manufacture of integrated circuits during maintenance. The system detects when the transfer chamber lid is opened and the chamber is exposed to the atmosphere. This activates the heater normally used to bake out the chamber. A temperature sensor is used to keep the temperature below a set point. By warming the chamber, moisture build-up on the inside of the chamber during maintenance is minimized, thereby reducing out gassing and time required to bring the chamber back to its base vacuum pressure when returned to production.

摘要： The invention is directed to a seal assembly for sealing an electrode movable vertically through an opening in the roof of an electrode furnace. The seal assembly comprises a lower assembly including an annular base adapted for sealing engagement with the roof around the roof opening, an annular wall extending up from the base, and an annular scraper extending generally radially inwardly relative to the wall and having an inner edge adapted for scraping material from the outer surface of the electrode as the electrode moves vertically. The seal assembly also includes an upper assembly comprising a pair of annular seals of refractory material disposed in vertically spaced relation, each seal comprising a plurality of discrete arcuate seal segments, a mechanism for applying an inward radial pressure to each seal to hold it in sealing engagement with the electrode, and a mechanism for holding each seal against upward movement relative to the roof as the electrode moves up through the roof opening.

摘要： An electrode assembly for an electric arc furnace incorporates a water cooled sleeve which extends downwardly from an electrode clamp around a portion of a consumable electrode held by the clamp. During normal electrode movement, the sleeve is preferably telescopically received within, but spaced from, a water cooled annulus defining an opening in a furnace roof. A sliding seal is provided acting between the sleeve and the annulus, of a form which allows the sleeve to be lifted upwardly out of and re-inserted into engagement with the annulus. The annulus may be extended vertically to shroud the sleeve.
