摘要： A method of cooling section steel, particularly sectional steel girders, from rolling heat, wherein, prior to a final air cooling, a water cooling process is carried out in such a way that section steel portions with material concentrations are cooled at outwardly projecting portions of the steel sections over a width of application and a duration of application which are variable and subject to a predetermined cooling strategy supported by a process computer to a value which is at least still slightly above the transformation temperature Ar1.

摘要： A continuously cast strand is cut into elongated billets having ends and the billets are run through a rolling stand. after cutting the strand into billets and before rolling the billets one of the billets is engaged in the rolling stand and a trailing end of the one billet and a leading end of another billet are enclosed in a mold with the ends longitudinally spaced. This space between the ends is filled with molten metal in contact with the ends of the billets and the molten metal is hardened to interconnect the billet ends. Then the mold is removed from around the billet ends. The molten metal is of substantially the same composition as the billets. Furthermore the one billet is advanced in a travel direction by means of the stand and the mold and the other billet are advanced synchronously with the one billet after enclosing the billet ends in the mold. The mold is removed from the billet ends before the hardened metal between the billet ends enters the rolling stand.
摘要翻译：将连续铸造的线材切割成具有端部的细长坯料，坯料穿过轧制机架。在将线材切割成坯料之后并且在轧制坯料之前，其中一个坯料接合在轧制机架中，并且一个坯料的后端和另一坯料的前端被封闭在模具中，其端部纵向间隔开。端部之间的该空间填充有与坯料的端部接触的熔融金属，并且熔融金属被硬化以使坯料端部相互连接。然后将模具从坯料端部周围移除。熔融金属的组成与坯料基本相同。此外，一个坯料通过支架和模具在行进方向上前进，并且另一个坯料在将坯料端部封装在模具中之后与一个坯料同步前进。在坯料端部之间的硬化金属进入轧制机架之前，将模具从坯料端部移除。

摘要： A method of straightening rolled sectional steel includes clamping and subsequently cooling at least a sectional steel whose maximum local cross-sectional temperature is below Ar1 and whose minimum local cross-sectional temperature is above a lower limit temperature, wherein already the lower limit temperature produces as a result of clamping a thermal elongation in all fibers of the sectional steel which is greater than the elongation which would be required for a plastification of the fibers which would be subjected to the greatest internal compressive stresses if the sectional steel were exclusively air cooled without clamping.

摘要： A method of coiling or placing bar steel or wire in coils, wherein the rolling stock is reeled from rolling heat in a basket or is placed by a coiler in the form of coils onto a conveyor and is collected at the end of the conveyor over a mandrel into a coil, wherein the rolling stock is cooled during coiling and the rolling stock is further cooled after the coiling process or the formation of coils. Cooling of the rolling stock from rolling heat prior to coiling into the transformation range characterized by the Ar.sub.3 line or Ar.sub.1 line of the transformation time-temperature diagram corresponding to the type of steel to be cooled is extended, such that, depending on the type of steel, the rolling stock is transformed immediately after cooling prior to, during or after coiling, uniformly over the entire length and entire cross-section thereof essentially isothermally from the austenite phase into the ferrite phase or pearlite phase and, as required, into the bainite phase.
