前言现代化的大型板坯连铸机组为着适应生产断面大(170～300×1600～2200毫米)、生产率高(拉坯速度1.2～2.0米/分)以及长时间在高温下运转等特殊工艺条件,采用了一系列的新型机械装置,如钢包旋转台架,可调结晶器,液压夹紧的辊式二次冷却系统,多辊拉矫装置等等。这些新型机械装置的出现,不仅体现了连铸工艺的技术要求日趋严格,而且也体现了连铸技术向高效率
Preface The modern large-scale slab continuous casting unit is suitable for the special production conditions (170 ~ 300 × 1600 ~ 2200 mm), high productivity (1.2 ~ 2.0 m / min) and long time under high temperature , Using a series of new mechanical devices, such as ladle rotating gantry, adjustable mold, hydraulic clamping of the secondary cooling system, multi-roll straightening device and so on. The emergence of these new mechanical devices, not only reflects the increasingly stringent technical requirements of continuous casting process, but also reflects the continuous casting technology to high efficiency
