20100051306 | HIGH VOLTAGE BUSHING - A high voltage bushing for transferring AC or DC high voltage and current. The bushing includes an electrically connectable electrical conductor, an insulator housing enclosing the conductor, and a space filled with an electrically insulating gas in between said insulator housing and said conductor. The electrical conductor is coated with a surface layer of a material having a thermal emissivity substantially larger than a thermal emissivity of the conductor. | 03-04-2010 |

20130269483 | Apparatus And Method For Electromagnetic Stirring In An Electrical Arc Furnace - An apparatus for electromagnetic stirring of the steel melt in an electrical arc furnace includes two electromagnetic stirrer units, a current supply, and a control unit. The two stirrers are mounted on an outer bottom surface of the electrical arc furnace at opposites sides of a central position of the bottom surface, the current supply is operatively connected to the two electromagnetic stirrer units, and the control unit is operatively connected to the current supply to control the operation of the two electromagnetic stirrer units. | 10-17-2013 |
20140175715 | Method And Arrangement For Vortex Reduction In A Metal Making Process - A method for reducing vortex formation in molten metal when bottom tapping the molten metal from a metallurgical vessel in a metal making process. The method includes the steps of tapping the molten metal via a tapping hole in the metallurgical vessel, and providing a flow of the molten metal in the metallurgical vessel while tapping via a time-varying electromagnetic field applied to the metallurgical vessel, the flow of the molten metal being such that it constantly moves vortices in the molten metal away from a tapping hole region during the tapping to thereby prevent accumulation of the vortices for vortex formation over the tapping hole. It is also presented an arrangement for carrying out the method. | 06-26-2014 |
20140318314 | Method For Melting Steel - A method for melting steel in an electric arc furnace (EAF). A hot heel is provided in the EAF. Metal scrap is loaded into the EAF. The metal scrap is melted in the EAF. The mass of the hot heel in relation to the mass of the metal scrap that is initially beyond the surface of the hot heel is a certain minimum. This minimum is 0.75 times the relation between the heat required to melt the metal scrap beyond the surface of the hot heel and the heat that can be taken from the hot heel without it being solidified when a theoretical heat balance calculation is applied as defined in a formula. | 10-30-2014 |

20100072219 | STACK - The invention relates to a stack of discrete material sheets, which material sheets have a longitudinal direction and a transverse direction. The material sheets forming the stack are placed with their transverse end portions partially overlapping material sheets are folded at least once along a fold line in the longitudinal direction to form an assembled web, which direction corresponds to the dispensing direction of the stack. The assembled web is folded along fold lines in the transverse direction to form the stack of material sheets. The material sheets are interlinked in such a way that, when a first material sheet is extracted, a predetermined part of a subsequent material sheet is fed out. | 03-25-2010 |
20100075096 | ROLL - The invention relates to a roll of material sheets, which material sheets have a longitudinal direction and a transverse direction, wherein the roll includes discrete material sheets. The material sheets are folded at least once in the longitudinal direction, which direction corresponds to the winding direction of the roll. The material sheets being interlinked in such a way that, when a first material sheet is extracted, a predetermined part of a subsequent material sheet is fed out. | 03-25-2010 |
