阿维迪无头带钢生产保证低成本

钢铁生产总投资低​

由于设计紧凑，无头带钢生产(ESP)与其他薄板坯连铸连轧工艺相比生产线长度缩短50%之多，占地面积大幅减少。 与传统工艺相比，ESP使绿色钢铁生产节省了多达80%的面积。

除了减少土地占用，ESP 还大幅降低了投资成本(CapEx)，因为

• 减少了基础施工
• 减少了钢结构
• 减少了墙面覆层
• 减少了屋面铺设
• 减少了管道
• 减少了布线

轧钢的低生产成本

由于设计紧凑，第一步轧制充分利用了铸流的热量，加上感应加热效率高且只在实际铸轧生产时消耗能量，能源得以节省。
由于感应加热炉长度极短使维修工作显著减少，而且无头运行模式使工作辊使用寿命延长一倍，耗材得以节省。
由于无头运行避免了切头切尾损失，而且紧凑的布局缩短了氧化时间使带钢表面氧化皮显著减少，收得率得以提高。
由于采用单流运行和取消了板坯存，人力成本得以降低。

专门的无头生产线消除了其他生产模式(比如单卷轧制)的弱点，而它的诸多优点完全超过了多种生产模式所声称的灵活性。

阿维迪无头带钢生产(ESP)是一种在连铸和轧制过程中实现温室气体零排放的工艺。 2009年以来，阿维迪ESP线已经生产了超过1亿吨CO₂直接排放为零的绿色钢，与传统连铸连轧工艺相比CO₂排放总共减少了3,100万吨。

热轧工作辊寿命延长一倍

阿维迪无头带钢生产(ESP)的工作辊磨损较轻，因为无头工艺避免了板坯咬入对工作辊的冲击和损坏。 由于第一步轧制在铸流芯部尚软时直接进行，带钢能够在较小的轧制力下很好地成形。 后部精轧机架上采用能够实施磨损补偿的工作辊窜辊，使工作辊使用寿命比其他工艺延长了一倍。

无头带钢生产减少了合金需要量

HSLA或API钢种的热机轧制需要保持在非再结晶温度以下，还要通过过度合金化加以保证。 与这种策略相反，稳定的ESP无头运行和超早期强力冷却达到的极高冷却速度有利于取消这种过度合金化。 这样就能减少必需的合金化元素(比如铌、镍、铬或钼)的用量。
