转炉生产的钢水在精炼炉中精炼后，需要将钢水浇铸成不同类型和规格的钢坯。连铸段是将精炼钢水连铸成钢坯的生产过程。主要设备包括转盘、中间包、模具和张力矫直机。
The non-sinusoidal vibration technology of the mold has significant effects in improving the drawing speed, improving the surface quality of the casting slab, and reducing the leakage rate. This technology can not only increase the drawing speed of the continuous caster, increase the productivity, reduce the leakage of the continuous caster, and stabilize the production of the continuous caster, but also can provide high-quality cast slabs for rolling and improve the quality of the rolled material. To
The ladle containing refined molten steel is transported to the turntable. After the turntable rotates to the pouring position, the molten steel is injected into the tundish, and the tundish distributes the molten steel to each mold through the nozzle. The mold is one of the core equipment of the continuous casting machine, which makes the casting shape and rapidly solidify and crystallize. The tension leveler and the crystal vibration device work together to pull out the castings in the crystallizer, and cut them into slabs of a certain length after cooling and electromagnetic stirring.
Continuous casting automation control mainly includes continuous casting machine drawing roll speed control, mold vibration
控制技术，如动态变频控制和定长切割控制。连铸连轧要求连铸机能够生产出高温钢坯，并且所铸钢坯具有较高的表面质量和内部质量。同时，要求连铸机具有稳定的高生产率和高拉拔速度，以满足高速轧制的需要。结晶器非正弦振动技术是连铸连轧的关键技术。
轧机飞轮在轧制过程中承受冲击载荷。轧机通过飞轮和减速器带动轧机。一部分负荷由飞轮释放。轧机的主传动要求高动态响应和高过载能力。飞轮广泛应用于切割机、冲压机械等。飞轮辐条采用环形平面板结构，其厚度与飞轮相近。轧机飞轮工作在最佳状态，可以减少电机发热，节省功率。

当轧机处于负荷状态时，轧机飞轮减速并释放能量帮助电机克服峰值负荷。辐条与轮毂之间的厚度变化梯度小，消除了连接处容易产生应力集中和裂纹的结构缺陷。在变化条件下增加飞轮厚度，减小飞轮直径也有利于应力分布均匀，提高承载能力。当间隙内没有负载时，飞轮加速并储存能量，因此电机负载可以均匀。在拧紧螺母等时，严禁用锤子或淬硬钢件敲击，安装时还应检测飞轮的静平衡。

新型高产轧机设备配有在线多矫直机和冷床后冷切到长度的飞剪。轧制件经冷却床整个长度的多个长度进行拉直，然后使用切削刃。带孔型的飞剪机将轧制件切割成商业剪切长度。机架式步进式冷床用于均匀冷却轧制件，圆钢、螺纹钢等简单截面钢冷却后平整度好，无需矫直即可交货。对于槽钢、角钢、工字钢等异型材料，需经冷却床冷却后进行矫直。双尺冗余矫直，大大减少了咬头次数，事故少，效率高。采用该技术和设备，生产机械化，自动化程度高，大大减少了精加工面积和操作人员。
