摘　　要：传统的扁钢丝 ,特别是宽厚比大于 5的扁钢丝生产工艺复杂 ,能耗高 ,生产周期长 ,且大多需要多次的退火热处理 ,在没有保护气氛的条件下很容易脱碳。采用电接触加热的方法 ,将钢丝加热到轧制温度 ,一次粗轧成型 ,很好地解决了传统生产工艺上存在的问题。可提高成材率 3% ,降低能耗 2 5 %～ 40 %The production technology of traditional flat steel wire,especially the flat wire whose flakiness ratio is greater than 5,is complex Its energy consumption is high,production cycle is long,and it mostly needs annealing heat treatment many times Decarbonisation is easy of occurring without protective atmosphere The problems in traditional production technology may be solved by adopting electric contact heating method to heat steel wire to rolling temperature and shape with one pass breakdown,which can improve rate of finished products 3%,cut down energy consumption 25%～40%
