摘要
研究了南京钢铁集团公司炼钢厂 10 0 0mm× 180mm板坯连铸结晶器喂铝丝的工艺 ,结果表明 ,在铸坯拉速 1.0 9～ 1.2 2m/min、铝丝喂速 15～ 2 0m/min、喂铝量 167.2 6～ 2 49.61g/t时 ,铸坯Al含量均匀 ,改善了Q3 45q钢板材的机械性能。
The process of feeding aluminium wire in 1 000 mm×180 mm slab concasting mould at Nanjing Iron and Steel has been studied. The results showed that with concasting velocity 1.09～1.22 m/min, aluminium wire feeding rate 15～20 m/min and aluminium feeding amount 167.26～249.61 g/t, the Al distribution in concasting slab was homogeneous and the mechanical properties of Q345q steel plate were improved.
