对H08A焊接用盘条批量试制中出现的强度偏高、性能不稳定及组织异常进行了分析,优化了轧后控冷工艺。结果表明,采用吐丝温度(920±10)℃,风冷辊道速度0.30 m/s的控冷工艺,H08A盘条性能稳定、组织良好。
The high strength, unstable performance and abnormal structure appeared in the trial production of H08A welding wire rods were optimized, and the controlled cooling after rolling was optimized. The results show that the H08A wire rod is stable and well-knitted with a controlled cooling process with a spinning temperature of 920 ± 10 ℃ and an air-cooled roller speed of 0.30 m / s.
