    • Method to preheat billets, blooms or slabs, before rolling (14), as they arrive from a store of cold charges (10) or from continuous casting (11), such method involving a preheating furnace (12) and a heating furnace (13), the preheating (12) and heating (13) furnaces being connected in coordination, in which method:

      - material (15) arriving from the store of cold charges (10) passes through the preheating furnace (12) and the heating furnace (13),
      - material (17) arriving from the continuous casting (11) but momentarily halted due to work in progress in the rolling plant (14) is transiently stored in the preheating furnace (12) and is then passed through the heating furnace (13) when such work has ended and rolling can restart,
      - and material (18) coming from the continuous casting (11) passes through the heating furnace (13) before reaching the rolling process (14) during a normal cycle.
    • 在从冷藏库(10)或连续铸造(11)到达轧制(14)之前预热坯料,坯料或板坯的方法,包括预热炉(12)和加热炉(13)的方法 ),预热(12)和加热(13)的炉子协调连接,其中: - 从冷装料仓(10)到达的材料(15)通过预热炉(12)和加热炉 13), - 从连续铸件(11)到达但由于在轧制设备(14)中进行中的工作暂时停止的材料(17)瞬时储存在预热炉(12)中,然后通过加热炉 13)当这样的工作已经结束并且轧制可以重新开始时 - - 在连续铸造(11)中的材料(18)在正常循环期间在到达轧制过程(14)之前通过加热炉(13)。
