摘要:
Die Erfindung betrifft ein Montagehilfsmittel (1), bestehend aus einer Gewindehülse (4) mit einem Haken (5), die beweglich in dem Montagehilfsmittel (1) angeordnet sind, wobei das Montagehilfsmittel (1) mindestens aus einer Deckplatte (2) und einer bügelartig daran befestigten Hebeöse (3) besteht und die Gewindehülse (4) eine Wegstrecke durch die Deckplatte (2) ausführen kann, insbesondere für die Verwendung bei der Elektrodenstrang-Montage aus miteinander verschraubten Elektrodenabschnitten, bei dem die Gewindehülse (4) mindestens eine solche Wegstrecke durch die Deckplatte (2) des Montagehilfsmittels (1) bewegt werden kann, wie für die Schraubverbindung eines Elektrodenabschnitts mit einem Nippel notwendig ist, wobei die Wegstrecke durch ein am oberen Ende der Gewindehülse (4) angeordnetes Sicherungselement (10) begrenzt ist, welches das Herausschrauben zuverlässig verhindert.

摘要:
A method for periodic elongation of the electrode for the electric arc furnace and the electrode for the electric arc furnace. The method includes screwing on the electrode column of an earlier prepared new electrode and a nipple with a longitudinal through hole with a metal rod in it, for example made of aluminium or copper, which is melted under the working temperatures of the electrode column with filling up cavities in the joint "electrodes-nipple", as well as with partial filling of the additional cavity in the body of the electrode, the gas mixture from the space of the additional cavity free of liquid metal being drawn to the working area of the furnace through provided holes in the body of the said electrode. The electrode for the realization of the said method is made with additional cavities, placed along the central axis in the bottom of the threaded sockets, the said cavities having different diameters and depths and one of them being connected to the external surface of the electrode by means of holes.
摘要:
A submerged arc furnace (10) produces foundry iron from scrap iron and steel sources where little or no slag is produced. Scrap iron or steel is fed into the submerged arc furnace (10) with a source of silica and a carbonaceous reducing agent. The scrap iron and steel is melted while simultaneously smelting the silica in the presence of the carbonaceous reducing agent. The amount of the silica source and carbonaceous reducing agent are added in an amount to selectively control the silicon and carbon content of the resulting foundry iron.
摘要:
The present specification describes an electrode having an electrode joint for threadably joining two abutting carbon upper and lower electrode sections 10,20 with a locking pin 150 releasably held in the upper electrode section 10 which when released engages a groove 120 in the lower electrode section 20.
