摘要： The invention relates to a casting device comprising at least one tundish (10) for molten metal, in addition to an assembly (8, 11-14) for maintaining a predetermined level (N) of molten metal in the tundish (10). A metal strand is discharged by being fed through a die (15) into a shaping device. The assembly (8, 11-14) for maintaining the level (N) of the molten metal comprises a metering pump (8) in the tundish (10), said pump for metering purposes having an adjustment system (11-14; 19-21) for a selectable level (N). In addition, the outlet of said tundish is equipped with a die (15; 115) for discharging the metal into a continuous shaping device or into another die.

摘要： Die Erfindung ermöglicht es auf besonders wirtschaftliche Weise Stahlbänder (S) mit einer hohen Härte ihrer Oberflächenschichten und dementsprechend hoher Verschleißfestigkeit zu erzeugen, indem ein Coil (C), das aus einem einen Ausgangsgehalt an Kohlenstoff aufweisenden Stahlband (S) derart gehaspelt ist, dass seine Lagen mit Abstand zueinander angeordnet sind, bei einer oberhalb der A c3 -Temperatur liegenden Reaktionstemperatur einer Glühung unterzogen wird, bei der ein aufkohlendes Gas (RGas) durch den zwischen den einzelnen Lagen des Coils (C) vorhandenen Raum geleitet wird, bis in der Randschicht des Stahlbands (S) ein gegenüber dem Ausgangsgehalt um mindestens 0,1 Gew.-% erhöhter C-Gehalt erreicht ist.

摘要： The invention relates to a method for producing a steel strip (S) which is provided with a zinc coating. According to said method, the steel strip (S) continually passes through a strip galvanizing process in which it is subjected to hot dip galvanization in at least two steps. In the first hot dip galvanization step, the steel strip (S) is coated with a base layer (G), said steel strip being guided through a first dipping bath (2) consisting of a zinc melt with a low aluminium content for a first dipping time. After being coated with the base coat (G), the steel strip (S) is cooled. In a second hot deep galvanization step, a cover layer (D) is applied to the steel strip (S) coated with the base coat (G) by guiding the same through a second dipping bath (8) consisting of a zinc melt with a higher aluminium content than the first zinc melt, for a second dipping time.

摘要： The invention relates to a method for the production of hot strip or sheet, whereby a micro-alloyed steel, containing, in addition to the microalloying elements ( in wt. %) C: 0.05 0.12 %, Si: 0.2 0.5 %, Mn: 1.5 2.2 %, Al: 0.02 0.05 %, P: ≤ 0.025 %, S: ≤ 0.01 %, the remainder as iron and unavoidable impurities, which is cast to give an input stock in the form of slabs, pre-blocks or thin slabs. The input stock is heated to a temperature of 1300 - 1350 DEG C, pre-rolled with a deformation value of 36 % to 43 %, the pre-rolled input stock is thermomechanically hot-rolled at a rolling end temperature above the Ac3 temperature, the hot strip is cooled at a rate of at least 15 DEG C/s to a winding temperature of at least 590 DEG C and at most 630 DEG C and the hot strip finally wound. Hot strips can thus be produced economically, which even at high thickness can have a particularly high strength, by the above method.

摘要： The invention relates to a cold-rolled steel strip or sheet metal having a thickness of = 0.7 mm and used for electromagnetic purposes. Said strip consists of a steel containing (in wt. %) C: 1000 °C, and hot-rolled to form a heated strip at a hot-rolling temperature TF > 800 °C. Said heated strip is then cooled from a temperature TC of at least 750 °C but less than 850 °C to a temperature of less than 300 °C, at a cooling speed ΔT/Δt of at least 400 °C/min. After cooling, the steel strip is subjected to a surface treatment such as mechanical de-scaling and/or etching. After the surface treatment, the steel strip is cold-rolled at a maximum temperature TCR of 500 °C and is then annealed.

摘要： The invention relates to a method for separating crystalline graphite from a solids mixture containing carbon, particularly blast furnace dusts, with the purpose of producing superpure crystalline graphite or for highly precise determination of the purity level of solids mixtures containing crystalline graphite. According to the inventive method, the solids mixture containing carbon undergoes heat treatment in an aqueous solution which contains at least one oxidizing acid and/or one oxidizing agent or a non-oxidizing acid and an oxidizing agent at a maximum pressure of 1000 bar, whereby the acid and/or the oxidizing agent decomposes all substances of the solids mixture contained in the aqueous solution so that the crystalline graphite can then be separated from the aqueous solution using conventional separation methods.
