摘要
钢丝预处理过程中,原进口空气喷嘴锥面磨损严重,喷吹效果差,残留酸液易进入后道工序。将陶瓷套前移到离吹风口较近的位置,但由于寿命不长,换成硬质合金套,吹风口锥面得到保护,喷嘴平均寿命由原来的10 d延长到3个月。初步改进后吹酸效果不稳定,将喷嘴锥角由60°改进为90°,可以达到清洁的效果,但钢丝易被刮伤,合金套与陶瓷套并用能够解决刮伤问题。改进后,每条生产线的喷嘴年平均消耗量从40个下降到3.1个。
In steel wire pretreatment process,conical surface of original imported blow nozzle worn seriously,blowing effect is bad,residual acid can be brought to next procedure.Ceramic bushing is moved to the position near blowing,but its lifetime is short,after it is changed into cemented carbide bushing,the conical surface of blowing is protected,average lifetime of nozzle was prolonged from 10 days or so to 3 months.The effect of acid blowing after initial improvement is unstable.It can get cleaning effect after changing nozzle cone angle from 60° to 90°.But steel wire is scratched easily,the problem can be solved by adopting cemented carbide and ceramic bushing.The annual average nozzle consumption of each production line is decreased from 40 to 3.1 after improving.
