Preparation method of high-cleanliness steel for hollow stabilizer bar of new energy automobile

The invention belongs to the technical field of steelmaking, and particularly relates to a preparation method of high-cleanliness steel for a hollow stabilizer bar of a new energy automobile. The aluminum content in the LF refining process is controlled at a low level by adding aluminum blocks behind a converter and feeding aluminum wires in an argon blowing station for deep deoxidation, the RH adopts a vacuum light treatment mode, the aluminum loss in the vacuum treatment process is reduced, and the aluminum content is adjusted to a target value in the final stage of vacuum. The steel produced through the technology is high in cleanliness, inclusions in molten steel are a small amount of small-size low-melting-point calcium aluminate, and oxide inclusions can meet the requirements that B fines, B coarseness, D fines and D coarseness are smaller than or equal to 1.0 grade, and Ds is smaller than or equal to 0.5 grade. 本发明属于炼钢技术领域，具体来说涉及一种高洁净度新能源汽车空心稳定杆用钢的制备方法。通过转炉炉后添加铝块及吹氩站喂铝线深脱氧，控制LF精炼过程铝含量在较低水平，RH采用真空轻处理模式，
