西西伯利亚联合企业生产金属制品时,在贯通式辊底炉中采用两种温度规范(1～5炉区的温度℃见下表)对Ст1кп、Ст2кп、Ст3кп、10、20、35、20Г2Р和08Г2С钢的钢丝进行再结晶退火。退火后钢丝的机械性能基本上符合所要求的水平。然而,在以较小的断面收缩率拉拔的钢丝中,观察到再结晶过程未能完全进行的情况,因而在冷减径试验时,具有低延性、高强度以及不符合要求的显微组织。此外,不同的退火制度,带来了生产组织上的困难:例如,必须把待处理的钢丝编成组(这样就不能合理地利用车间面积);调整温度规范时(用于调整温度的时间长达
West Siberia joint production of metal products, the use of two kinds of temperature specifications (1 ~ 5 furnace temperature ° C below table) in the through-type roller hearth furnace for Ст1кп, Ст2кп, Ст3кп, 10,20,35,20 Г2Р and 08 Г2С Steel wire recrystallization annealing. After annealing the mechanical properties of the wire basically meet the required level. However, in the wire drawn with a smaller reduction of area, the recrystallization process was not observed to be completely performed, and therefore, in the cold reduction test, the microstructure having low ductility, high strength, and unsatisfactory properties . In addition, different annealing regimes give rise to difficulties in production organization: for example, the steel wires to be treated must be grouped (so that the workshop area can not be utilized properly); when the temperature regulation is adjusted Up to
