Abstract: A caterpillar track drawing method includes drawing a workpiece through a drawing die using a caterpillar track disposed behind the drawing die as seen in a drawing direction; and drawing a workpiece along a drawing line aligned parallel to the drawing direction while forming the workpiece by the drawing die. The caterpillar track includes circulating first and second drawing chains including chain links circulating parallel to a drawing plane. Each drawing chain is guided around first and second chain wheels having first and second axes aligned perpendicular to the drawing plane At least one measurable variable, inherent to the caterpillar track, of modules of the caterpillar track that resist or apply drawing force is recorded and optionally used for activation of a manipulated variable. In another aspect, a caterpillar track drawing machine includes the drawing die, the caterpillar track, and at least one measurable variable recorder.

Abstract: A burner comprises a primary nozzle for injecting an oxygen-rich gas. The primary nozzle is designed as a supersonic nozzle. A coaxial nozzle having an annular outlet opening is provided for injecting a fuel gas. The coaxial nozzle is designed as a subsonic nozzle and is coaxial to the primary nozzle. The primary nozzle has a convergent portion and a divergent portion, which adjoin each other at a radius of the narrowest cross-section. The annular outlet opening is located at an end face of the burner. The fuel gas, in the form of hydrogen or a mixture of hydrogen and a hydrocarbon-containing gas, is injected at a fixed inlet pressure and a fixed inlet volumetric flow rate, with respect to a planned thermal power of the burner. In contrast, the inlet pressure and the inlet volumetric flow rate of the oxygen-rich gas are varied according to the application.

Abstract: A method for obtaining metals of the 8th to 14th groups, in particular raw copper, comprises the following steps: i) providing and melting down a mixed feed comprising electronic waste in a smelting reactor, so that a first melt with a first metallic phase and a first slag phase is formed; ii) separating out the first slag phase from the smelting reactor; iii) refining the remaining first metallic phase by means of an oxygen-containing gas, possibly with the addition of copper-containing residual materials, so that a second, copper-enriched slag phase is formed; iv) possibly separating off the second slag phase and repeating the step; v) separating off the refined first metallic phase from the smelting reactor; and vi) adding a further mixed feed comprising electronic waste to the remaining second, copper-enriched slag phase and repeating process steps i) to vi).

Abstract: A method for open-loop and/or closed-loop control of a heating of a cast or rolled metal product, includes the steps of determining the total enthalpy of the metal product from a sum of the free molar enthalpies (Gibbs energy) of all phases and/or phase fractions currently present in the metal product; determining a temperature distribution within the metal product by means of a dynamic temperature calculation model using the total enthalpy determined; and open-loop and/or closed-loop controlling of the heating of the metal product as a function of at least one output variable of the temperature calculation model.

Abstract: The disclosure relates to a method for controlling a stretch-reducing mill. Tube ends of stretched tubes are optimized by controlling one or more motors of the stretch-reducing mill. The method includes at least one outlet-side wall thickness measurement and an automatic adjustment of the value of a speed change of the motors to the tube wall thickness profile. The progression of the speed changes over time of individual or all motors is also automatically adjusted on the basis of the tube wall thickness measured values.

Abstract: An improved apparatus for producing steel, including a lower furnace, an annular, water-cooled, fireproof lined cylindrical upper furnace, on which an upwardly closing conically tapering hat having openings can be placed. The smelting assembly is configured for the operational mode without melt flow and the operational mode with melt flow. To this end, at least one opening is provided in the conical furnace cover, through which opening at least one top lance can be introduced into the upper furnace. A plurality of sidewall injectors radially rotate around the cylindrical upper furnace in such a way that in a working position, the top lance and the sidewall injectors are directed onto a smelt level of a molten mass located in the lower furnace for refining.

Abstract: A method for the post-combustion of exhaust gases comprising carbon monoxide from metallurgical processes includes conditioning the exhaust gas prior to post-combustion by metering a combustion gas and/or one additional gas in feedback-controlled fashion. The feedback control depends on the composition of the exhaust gas dependent on the exhaust gas volume flow. A device for post-combustion of exhaust gas during vacuum treatment of liquid steel comprises a flare stack at an exhaust outlet, means for feeding combustion gas to the flare stack, means for feeding an inert gas into the exhaust gas channel of the vacuum pump, means for ascertaining the exhaust gas volume flow and/or for measuring the exhaust gas velocity within the exhaust gas channel, means for analyzing the exhaust gas composition, means for metering the combustion gas and the inert gas, and means for feedback control of the metering of the combustion gas and/or the inert gas dependent on the exhaust gas composition.
