转炉生产的钢水在精炼炉精炼后，需要将钢水铸造成不同类型、不同规格的钢坯。连铸段是将精炼的钢水连续浇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
动态频率控制、定长切割控制等控制技术。连铸连轧要求连铸机能够生产出高温钢坯，并且铸出的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、高的生产率和高的拉深速度，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受到冲击载荷。轧机通过飞轮和减速机驱动轧机。一部分载荷由飞轮释放。轧机主传动对动态响应和过载能力要求高。飞轮广泛应用于切割机械、冲压机械等。飞轮辐条采用与飞轮厚度相近的环形平面板结构。轧机飞轮工作在最佳状态，可降低电机发热，节省动力。

当轧机处于负荷时，轧机的飞轮减速并释放能量，以帮助电机克服峰值负荷。轮辐与轮毂厚度变化梯度小，消除了接缝处易产生应力集中和裂纹的结构缺陷。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，增加承载能力。当间隙无负载时，飞轮加速并储存能量，使电机负载均匀。、拧紧螺母等时，严禁用锤子或淬火钢件击打，安装时还应测试飞轮的静平衡。

新型高成材率轧机设备配备了在线多台矫直机和冷却床后的冷切长度飞剪。将轧后的工件经整个冷却床长度的多个长度拉直，然后使用切削刃。带孔型的飞剪将轧后的工件切成商用裁切长度。机架式步进冷床用于均匀冷却轧制件，简单截面钢如圆钢、钢筋等简单截面钢冷却后平整度好，无需矫直即可发货。槽钢、角钢、工字钢等异型材料，需经冷床冷却后进行矫直。双尺冗余矫直，咬头次数大大减少，事故少，效率高。采用该工艺和设备，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。
