摘要： To produce threaded steel tension members, steel is used with a C-content of 0.50 to 0.80%, preferably 0.75%, a Si-content of 0.20 to 0.50%, preferably 0.25%, and a Mn content of 0.30 to 0.80%, preferably 0.60%. Exiting from the rolling heat at the outlet side of the finishing stand after hot rolling, the tension member or rod is subjected to surface quenching by a cooling medium, preferably water, so that the steel in a rim zone R.sub.1 is transformed immediately and completely into martensite, while the heat content remaining in the core zone K.sub.1 does not effect a tempering of the martensite rim zone during the subsequent cooling beyond the range of the intermediate stage. Steel tension members of this type have a high ductility and toughness at a high yield limit and high strength, they are corrosion-resistant to a great degree and have a wear resistant surface which makes them particularly suitable for threaded tension rods in which the threads are produced either by a cold forming operation or hot rolled ribs.

摘要： In a treatment or processing or sewage sludge in the sense of recycling, where the sewage sludge is to begin with dried (T), subsequently converted (K) under anaerobic conditions at approximately 250.degree. to 350.degree. C. and finally is sintered at at least 1250.degree. C. in successive steps, it is proposed to perform all process steps including the conveyance of the commodity to be processed between the individual processing steps successively in continuous passage in a closed system. Only the vapors are removed in this system in the drying stage (T) and the conversion gases in the conversion stage (K) and they are condensed; the heat quantity contained in the flue gas generated during the sintering process (S) is utilized for heating to begin with the conversion stage (K) and after that the drying stage (T). Because the flue gases are used for heating the processing steps in the sequence of the naturally occurring temperature gradient, the processing of the sewage sludge is achieved so as to be nearly self-sufficient as far as the energy requirement is concerned, meaning the energy required for the processing is largely supplied by the calorific value of the organic ingredients contained in the sewage sludge itself. Because the sewage sludge is processed in a closed system, nefarious effects upon the environment are avoided.
