介绍了三机三流直弧型连续弯曲/矫直板坯连铸机核心装备技术，开发了大容量T型中间罐、重载高低轨式中间罐车、板坯内外弧液压振动装置和L形立式扇形段传动装置等。五年的生产实践证明了三流板坯连铸技术的可靠性与稳定性，实现了大型冶炼炉—连铸—热轧带钢生产节奏的合理匹配，可提高单台铸机产量至300万吨，进而减少铸机数量，从而降低钢厂的基建投资和后续生产的消耗；开发了一种新的连铸机型，实现了板坯生产的准高效化，符合钢铁工业绿色、低碳发展的趋势。

The core equipment technology of three-machine and three-flow straight-arc continuous bending/straightening slab caster was introduced. The large-capacity T-type tundish, heavy-duty high-low rail tundish, slab inner and outer arc hydraulic vibration device and L-shaped vertical sector transmission device have been developed. Five years of production practice has proved the reliability and stability of three-flow slab continuous casting technology, and realized the reasonable matching of production rhythm of large-scale smelting furnace, continuous casting and hot rolled strip steel. It can increase the output of a single casting machine to 3 million tons, thereby reducing the number of casting machines, thus reducing the infrastructure investment and subsequent production consumption of the steel mill. A new continuous casting model is developed to realize the quasi-high efficiency of slab production, which accords with the trend of green and low carbon development of iron and steel industry.
