0.70~1.10Alt)的生产工艺为90 t转炉-LF-VD-150 mm×150 mm方坯连铸-连轧。分析了成分、轧制温度、冷却速度对38CrMoAl钢组织的影响。通过将铸坯加热温度、开轧温度和吐丝温度分别由(1100±40)℃
(1020±20)℃(和(900±15)℃降至(1060±40)℃
(980±20)℃和(840±15)℃
同时降低冷却线辊道速度
盘条HB硬度值由284~353降至221~254
显著降低冷拔过程的断丝率。
The production process of Φ8 ~20 mm coil of steel 38CrMoAl (/% : 0.35 ~0.42C

0.70 〜1.l0Alt) is 90 t converter-LF-VD-150 mm X 150 mm billet casting-continuous rolling. The effect of chemical composition
rolling temperature and cooling speed on structure of steel 38CrMoAl has been analyzed. With decreasing the billet heating temperature
beginning rolling temperature and coil laying-off temperature respectively from (1100±40)℃
(1 020 ± 20 )℃ and ( 900 土 15)℃ to (1 060 ± 40)℃
(980 ±20)℃ and (840 ± 15)℃
the HB hardness scale of coil decreases from 284 〜353 to 221 〜254 obviously to decrease the wire breakage rate in cold drawing process of coil.
