所谓薄板坯连铸连轧技术,就是采用连铸机与轧机连接工艺生产尺寸接近最终成品的薄板坯(厚20～50mm)的技术。采用薄板坯连铸连轧技术不仅简化了生产工序(省去了板坯加热、剪切和粗轧)、降低了设备投资费用和减少了能源消耗,而且开辟了中、小型钢厂经济地生产板带材的新途径。采用薄板坯连铸连轧技术的主要前提条件为:(1)薄板坯应无缺陷;(2)连铸机、轧机等生产设备的生产 The so-called thin slab casting and rolling technology, is the use of continuous casting machine and rolling mill production process close to the final size of the thin slab (thickness 20 ~ 50mm) technology. The use of thin slab casting and rolling technology not only simplifies the production process (eliminating the slab heating, shearing and rough rolling), reducing equipment investment costs and reduce energy consumption, but also opened up the economy of small and medium-sized steel mills New way of board and strip. The main prerequisites for adopting the technology of thin slab continuous casting and rolling are: (1) the thin slab should be free of defects; (2) the production of continuous casting machines, rolling mills and other production equipment
