| 摘 要： | 中碳冷镦钢采用球化退火工艺实现软化,其具有生产周期长、能量消耗多等特点.为了提高生产效率和线材质量、保护环境、节省能源等,中碳冷镦钢软化越来越受到紧固件厂和钢厂的重视.对此,国内外近年来开展了大量的研究工作,希望能开发出免退火或大幅度缩短退火软化时间的优质线材.评述了中碳冷镦钢软化的片改球、微细化、在线软化3种方法和软化机制,得出在线软化是今后中碳冷镦钢球化发展的必然选择.

| Abstract: | Medium-carbon cold-heading steel is softened by the spheroidizing annealing technology which has long cycle and excessive energy consumption.The softening gets more and more attention from fastener and steel companies in order to increase production efficiency and wire quality,protect environment,and save energy.Therefore, considerable efforts have been made to develop the high-quality wire which doesn't need annealing or can shorten the annealing and softening time greatly.In this paper,the methods and mec... |
