摘要
通过1998年全年82B硬线盘条力学性能及对应的冶炼、浇铸及轧制生产工艺数据的统计分析,提出了影响硬线盘条力学性能的主要因素是盘条的规格、化学成分、添注时间、气温及钢坯缺陷等,并对其中的几个因素进行了重点研究。提出了以碳锰当量控制钢中的碳锰比,进而改善盘条力学性能及后续的冷加工能力的观点。同时还指出对铸钢中添注时间的控制应从添注目的出发,而不应单纯强调延长添注时间。特别是在气温较低时,应更多的注意添注流量、锭身注速、钢包温度、环境温度以及风力大小等因素。
Statistical analysis of mechanics property of 82B hard wire rod in the whole year of 1998 and of relevant technological data of smelting, casting and rolling shows that the main factors influencing mechanics property of hard wire rod are specification, chemical composition, additional injectoin time of the wire rod and temperature as well as the billet. Detail study implies C - Mn equivalent control on C - Mn proportion in steel could improve mechanics property of wire rod and the following cooling process; Attention should be paid to aim of the additional injection instead of the injection time; Specially under lower temperature more attention should be paid to injection flow control, teeming speed of chill, temperature of ladle, environmental temperature and wind intensity.
