摘要： THE CRUCIBLE OF AN INDUCTION FURNACE IS SURROUNDED BY AN UPRIGHT COIL THAT IS ENERGIZED BY ALTERNATING-CURRENT ELECTRIC POWER. THE POWER INPUT TO THE COIL IS OF SUCH A LEVEL THAT A RAISED, SLAG-FREE CROWN IS FORMED ON THE TOP OF THE MELT AND AT LEAST 55% OF THE SLAG PRODUCED IS RETAINED TO FORM AN ANNULUS AROUND THIS CROWN. THE CENTRALLY ASCENDING AND PERIPHERALLY DESCENDING CURRENTS IN THE FURROUS MELT CAUSE THE CROWN TO FORM AND ALSO INDUCE THE ANNULUS TO INTROVERT (CIRCULATE INWARDLY AND DOWNWARDLY) SO THAT LIGHT SPONGE IRON ADDED TO THE MELT IS DRAWN DOWNWARDLY INTO THE SLAG-STEEL INTERFACE AND QUICKLY HEATED AND BROUGHT INTO INTIMATE CONTACT WITH BOTH FLOATING SLAG AND THE FERROUS MELT. THE POWER IS FED TO THE COIL IN A MAGNITUDE DETERMINED BY THE RELATIONSHIP P>K(F**(1/2)) WHEREIN P IS THE POWER INPUT IN KILOWATTS PER TON OF THE MEL,T, K IS THE ANNULUS-FORMING CONSTANT AND IS GREATER THAN 45 AND PREFERABLY MORE THAN 49.5, AND F IS THE FREQUENCY IN HZ. OF THE ALTERNATING CURRENT.

摘要： Green (nonfired) pellets of iron ore are prepared by pelletizing the iron ore and 2 to 8 percent by weight of finely divided metallic iron with a particle size below 45 microns in the presence of an aqueous solution, suspension or dispersion of an organic binder, preferably a carbonhydrate. Surprisingly, the low-temperature binder, i.e. the starch, dextrine or the like, in combination with the metallic iron powder, affords considerable structural integrity to the pellets during the initial and subsequent stages of the direct reduction in a shaft-type or rotary furnace.

摘要： The device is for collecting runs of rod or wire to form coils after for instance the finishing stand of a rod mill or a heat treatment line or plant. The device has inner centering means and outer centering means for the turns to form a dimensionally stable coil, and there is a retractable member in the path of fall of the turns so that the device is divided into an upper collecting zone and a lower collecting zone. The inner centering means is divided so that there is inner centering both in the upper collecting zone and in the lower collecting zone. The upper part of the inner centering means is alternately supportable on the lower part of the inner centering means and upon the retractable member.
摘要翻译：该装置用于收集棒或线的运行以在例如棒磨机或热处理线或设备的精加工机架之后形成线圈。该装置具有内部对中装置和用于匝形成尺寸稳定的线圈的外部对中装置，并且在匝道的下落路径中存在可缩回构件，使得装置被分成上部收集区域和下部收集区域。内部对中装置被分割成使得在上部收集区域和下部收集区域中存在内部定心。内定心装置的上部可交替地支撑在内定心装置的下部和可缩回构件上。
