摘要： The invention relates to a method for the continuous production of steel wire or bar, wherein a first hot-forming is carried out by rolling at a temperature above the recrystallization temperature, and wherein the overall degree of forming during the first hot-forming is at least 60%. Next, the rolled steel is cooled to below the recrystallization temperature, and then a final forming takes place at a temperature in the range of the non-recrystallized austenite. The cooldown is carried out in a manner that inhibits a potential growth of grains in the austenite rolled steel before the final forming. The overall degree of forming during the final forming is at least 30%. Finally, the rolled steel is cooled down to a predetermined heat holding temperature at the Ar1 temperature and left at said temperature for a predetermined heat holding time.
摘要翻译：本发明涉及连续生产钢丝或钢条的方法，其中通过在高于再结晶温度的温度下轧制进行第一次热成型，其中在第一次热成型期间的总成型度为至少60％。接着，将轧制钢冷却至再结晶温度以下，然后在未再结晶奥氏体的范围内进行最终成形。冷却时间以抑制最终成形前的奥氏体轧制钢中的晶粒的潜在生长的方式进行。最终成型期间的整体成形度至少为30％。最后，将轧制钢冷却至Ar 1℃的预定的保温温度，并在所述温度下放置预定的保温时间。

摘要： The invention relates to a ball pin made of a steel comprising a bainitic microstructure having the following composition in weight percent: iron, and - 0.05 to 0.15 carbon - 0.10 to 0.4 silicon - 1.0 to 2.5 manganese - 0.0015 (15 ppm) to 0.0120 (120 ppm) boron, in total 0.06 to 0.30 of the elements vanadium, niobium, titanium. A method for producing the ball pin comprises at least the following steps: melting the steel; casting the steel in ingot casting or continuous casting; hot rolling; controlled cooling after the hot rolling; cold drawing; extrusion.
